In the UK, net energy consumption stood at 128.1 million tonnes of oil equivalent in 2024, with the industrial sector accounting for 19.5 mtoe – the lowest level in over 50 years – as efficiency measures and structural changes reduced energy use in industry. Even so, hydraulics remain a major power consumer in infrastructure and industrial equipment, and every inefficiency translates directly into wasted energy and operating cost.

Why every watt counts in hydraulic engineering?

When engineers focus on eliminating mechanical energy losses in fluid power, rather than adding complexity, measurable gains in efficiency and operating life can be realised. In this article, we look at where energy is physically lost within hydraulic systems and how engineering decisions can reclaim that loss without relying on digital intervention.

Cutting loss where it starts: reducing pressure drop through better flow paths

What is the biggest source of energy loss in any fluid power system? Pressure drop. In a commercial or industrial system, a high pressure drop means the pump must deliver more power to maintain performance, with the excess turning into heat. In construction plant and infrastructure applications, long runs of small-bore hose or poorly planned routing are common contributors to elevated pressure loss.

Specifying hydraulic hoses with larger internal diameters and designing flow paths that minimise abrupt directional changes will reduce frictional losses. Engineering models such as the Darcy–Weisbach relationship show that head loss decreases rapidly as diameter increases, which is why industry best practices emphasise selecting an adequate internal diameter to minimise pressure loss and the associated energy waste. In environments where the total system run length can reach hundreds of metres, smart design choices can clock up significant energy savings over years of service.

When valves become barriers: how component geometry affects flow efficiency?

Hydraulic valves are essential for motion and load control, but they can also be major contributors to wasted energy if their internal flow passages are not sized or shaped appropriately. Directional control, pressure relief and flow control valves all introduce resistance, and the resulting pressure drop across valves converts useful hydraulic power into waste heat. However, valves can also be used to create intentional restrictions within the system, safely dissipating excess energy as fluid passes through its internal passages.

The magnitude of this loss depends on your valve type, the internal geometry, and operating position. Valves operating continuously in throttling or partially open conditions dissipate more energy than those used primarily for on/off control. In construction equipment such as access platforms, lifting systems, or stabilisation circuits, sustained valve-related pressure losses are a common source of inefficiency.

To minimise unintentional energy losses caused by hydraulic valves, the key is to treat valves as engineered flow elements, and not just control devices. It’s a combination of the correct sizing, the correct selection, and the correct operating mode. Select your valves using manufacturer pressure –flow characteristics so that the required flow can pass with minimal pressure loss, avoiding continuous throttling wherever possible, and ensuring each valve type is used only for its intended function.

Valves should be sized and applied so they operate within their optimal flow range, with internal leakage kept within acceptable limits for the duty cycle. Your valve placements and circuit layout should shield the components from exposure to unnecessary differential pressures when control is not required.

Couplings, connections, and flow disturbance

Hydraulic couplings and fittings are often treated as secondary components in design engineering, but their influence on flow quality can be significant. Sharp edges or misalignments at connection points can disrupt flow and create localised turbulence. This turbulence increases resistance and contributes to pressure loss at each interface. In systems with multiple connections (common in mobile plant) these losses can accumulate. Selecting couplings with smooth internal profiles and maintaining the correct alignment during installation will help maintain a consistent flow profile and reduces unnecessary energy dissipation.

Heat as the consequence of inefficiency

All hydraulic energy losses ultimately appear as heat within the fluid, with a range of potentially damaging effects. Whenever pressure is lost through friction, throttling, leakage, or turbulence, the energy supplied by the pump is converted into thermal energy rather than useful mechanical work. This waste heat raises fluid temperature locally and, if sustained, across the entire system.

Elevated oil temperature has several compounding mechanical effects. For instance, as the temperature increases, fluid viscosity decreases, reducing the thickness and strength of the lubricating film between moving surfaces. This increases metal-to-metal contact within pumps, valves, and actuators, accelerating wear. At the same time, higher temperatures accelerate the chemical degradation of hydraulic fluid additives, reducing their ability to control oxidation, corrosion, and foaming. Seals and hoses may also be affected, as prolonged exposure to elevated temperatures hardens elastomers, reduces elasticity, and shortens service life.

In many industrial applications, hydraulic systems operate in confined spaces where airflow is limited and additional cooling capacity is impractical or undesirable. Under these conditions, managing heat after it has been generated becomes difficult and often inefficient. Larger oil reservoirs, heat exchangers, or forced cooling systems add complexity, cost, and additional failure points without usually addressing the underlying cause of the problem.

Minimising heat generation at source – by design – is therefore an important engineering objective. As we have seen, by reducing pressure losses, limiting internal and external leakage, and maintaining smooth, well-sized flow paths, you can directly reduce the amount of energy converted into heat within the system. This creates more stable operating temperatures, improves fluid condition, and reduces thermal stress on components.

The post Where Energy Is Lost (and Won Back) in Hydraulic System Design appeared first on Hydrastar.

In most hydraulic systems, the hydraulic gear pump usually gets the blame for any inefficiency! In many cases, however, the pump is often doing exactly what it was designed to do. The real energy losses (i.e. the ones quietly inflating your operating costs) typically occur downstream: in pressure drops, restrictive components, poor routing, and small leaks that go unnoticed for months. For maintenance engineers, this is good news. It means efficiency gains don’t always require new power units — just smarter component choices. Read on to find out more.

Undersized Hoses: Small Diameter, Big Losses

Hose sizing has a direct impact on pressure drop and energy efficiency. When your hoses are undersized, fluid velocity can increase significantly, and the higher velocity creates more friction between the fluid and the hose wall. That friction translates into pressure drop and heat generation, both of which represent wasted energy. The additional heat isn’t just a temperature issue, however; it also signals that the system is working harder than necessary. Every unit of pressure lost in a restrictive hose forces your pump to compensate by consuming more power. Selecting correctly sized hose assemblies reduces velocity, stabilises temperatures, and lowers frictional losses. In many systems, moving up just one hose size can meaningfully improve efficiency and extend oil life.

Restrictive Hose Couplings & Fittings

Even when the hose diameter is correct, restrictive hose couplings & fittings can often undermine system performance. Some quick couplings, adapters, and threaded connections reduce the internal flow area compared to the hose bore. Others introduce sharp internal transitions that disturb the flow and increase turbulence. Each of these small restrictions adds incremental pressure loss. When multiplied across multiple fittings and valves, the cumulative effect on your application becomes substantial. Specifying full-flow fittings and ensuring proper alignment between components helps maintain consistent internal diameter throughout the circuit. These seemingly minor upgrades can reduce system resistance and energy demand without changing the pump itself.

The Hidden Cost Of Poor Hose Routing

Hose routing is often treated as a layout convenience, but it also plays a measurable role in energy efficiency. Tight bends, unnecessary elbows, and excessive hose length increase flow resistance and create turbulence. Over time, this added friction not only wastes energy but also accelerates hose wear and contributes to localised heating. Optimised routing minimises directional changes and respects proper bend radius limits, allowing fluid to move more smoothly through your system. Cleaner routing also reduces friction losses and supports longer component life; a design improvement that pays dividends long after installation.

Leakage: The Silent Power Drain

Leaks are one of the most overlooked sources of energy waste in fluid power systems. While external leaks are visible, internal leakage often goes undetected, especially if fluid loss is negligible. Worn seals, improperly torqued fittings, and degraded bonded washers allow fluid to bypass pressure zones, reducing volumetric efficiency. When this happens, the pump must move more fluid to achieve the same output, increasing overall energy consumption. Over time, even small leakage points can lead to higher operating costs, greater oil contamination, and more frequent maintenance cycles. Regular inspection of connection points and sealing components helps prevent efficiency losses before they escalate.

When Is The Best Time To Review Your System Layout?

Scheduled maintenance intervals give you the ideal opportunity to review your overall system layout. Rising oil temperatures, unexplained increases in energy consumption, or components that seem to wear prematurely often signal hidden pressure losses. Rather than simply replacing parts as and when they fail, evaluating hose diameter, fitting selection, routing efficiency, and sealing integrity can uncover long term structural improvements you might otherwise have missed.

In 2024, the UK fluid power sector was worth an estimated £1.1 billion, with hydraulics accounting for around 80% of the total market. This is a buoyant market, and reflects growth conditions in fluid power around the world. According to Allied Market Research, the global hydraulic cylinder market was valued at (US)$14.07 billion in 2020 and is projected to reach $21.24 billion by 2030, representing steady long-term expansion (approx. 4% CAGR).

Challenges And Opportunities From A Growing Sector

This concentration matters for OEM procurement teams because it signals where utilisation pressure is highest: hydraulic cylinders, industrial hose couplings, and hydraulic hose fittings are central to maintenance and new-build activity across the manufacturing, construction, and mobile plant sectors. A growing market brings its share of challenges as well as opportunities, and in engineering procurement, long-term growth usually means three things:

1. Higher asset utilisation
2. Increased demand for spare parts, and
3. Potential lead time volatility

When equipment runs harder and longer, wear rates on hydraulic cylinders increase, seals cycle more frequently, and hose assemblies operate closer to their design limits. This is why some organisations are moving away from reactive purchasing strategies, and instead classifying hydraulic components by their downtime impact — ensuring critical cylinders are supported with planned seal kit stock and that high-volume hose fittings and couplings are standardised to reduce SKU complexity.

Pricing pressure is another feature of market growth cycles. The U.S.-based National Fluid Power Association (NFPA) – sister organisation to the BFPA here in the UK – reported that the Producer Price Index (PPI) for fluid power equipment rose 15% year-over-year in November 2025, reflecting strong inflationary and supply-side pressures within the industry. While this is American data, many hydraulic components are globally traded, meaning that similar cost trends can influence UK and European supply chains.

Procurement teams can respond by designing cost out of systems rather than negotiating unit price alone. For example, standardising hose fitting families, reducing one-off specifications, and clearly defining pressure, temperature, and corrosion requirements reduces the need for expensive substitutions later. Specification discipline, including adherence to recognised dimensional standards such as ISO 12151 (Hose fittings with ISO metric threads), further lowers the risk of mismatched threads and leakage failures: standardised couplings lower the risk of mismatch failures, and cylinders selected for the correct duty cycles reduce premature rebuild frequency. These are controllable variables, even in inflationary conditions.

However, demand signals can be uneven. NFPA shipment data from December 2025 showed overall fluid power shipments down 2.1% year-on-year, while hydraulic shipments were up 2.1% year-on-year; a reminder that hydraulics may remain strong even when other fluid power segments soften.

How Should Your Business Respond?

To navigate growth effectively, procurement teams must move from reactive purchasing to a more structured control strategy. This begins with visibility: identify high-consumption hydraulic hose fittings and apply clear min/max stock levels to prevent shortages during demand spikes. For repeat-use industrial hose couplings, blanket orders or scheduled call-offs can stabilise your supply levels and protect pricing.

Risk mitigation should follow close behind. Pre-approve technically equivalent alternatives so that maintenance teams are not forced into last-minute substitutions, and maintain tight technical specifications aligned with recognised dimensional standards to minimise compatibility errors and leakage risk.

What Next?

For our Hydrastar trade customers, the message is clear: growth increases opportunity but also your exposure to downtime risks. This is why a good trade supplier should do more than ship parts. They also have a strong role to play in reducing risk and simplifying your procurement channels.

With technical guidance to reduce compatibility issues, reliable availability on high-turnover components, rapid hose assembly support, and structured account management to simplify procurement, Hydrastar helps engineering and supply chain teams protect uptime, control cost, and avoid the disruption that comes from rushed substitutions or inconsistent supply.

The post Navigating Fluid Power Market Growth: Insight for Engineering Procurement and Supply Chain Teams appeared first on Hydrastar.

Historically, hydraulic systems have used mineral oil-based hydraulic fluid because of its lubricity, energy density, and stable operating characteristics under pressure. However, there are numerous reasons for OEMs to be uncomfortable with hydraulic fluid – not least the risk of environmental toxicity, and the workplace safety implications should a leak occur. These concerns have fuelled a search for water-based or sustainable hydraulic technology; one of the most interesting developments emerging in the sector in recent years. Read on to find out more.

What is water-based hydraulics?

Water hydraulics is not a new concept. The word hydraulic itself is derived from the Greek words hydro (water) and aulos (pipe or tube) – so, literally ‘water pipe’, with no oil required. Over time, however a ‘hydraulic system’ has grown to mean any fluid power network that uses a pressurised fluid to generate force, motion, or power, and in modern systems this fluid is typically a petrochemical oil.

So, water-based systems existed long before oil-based systems came to dominate, and modern materials and fluid conditioning methods have started to make them viable once more. As sustainability becomes a stronger priority across the heavy machinery, offshore engineering, and manufacturing sectors, water, or a water-glycol mix, is re-emerging as a realistic medium for power transmission.

Why use water as a hydraulic medium?

Water is clean, abundant, and non-flammable. Unlike mineral oil, there is minimal environmental impact if leaked, and in many cases, water requires a less complex containment infrastructure. These benefits have attracted attention in several sectors, including:

• Marine and offshore environments
• Food and pharmaceutical production facilities
• Forestry and environmentally sensitive land applications
• Fire risk areas such as foundries and underground mines

However, there are several challenges to water-based hydraulics. Firstly, water lacks the lubricity of oil and also causes a higher corrosion risk to metal components. Modern systems must compensate by using stainless steel components, corrosion-resistant coatings, and specialised water-glycol or seawater-compatible formulation to maintain equipment life.

Secondly, water-based hydraulics doesn’t always have the same power differential as oil-based applications, and this comes down to how the fluid behaves inside the system. Both systems rely on Pascal’s law, meaning that either fluid can generate high force when pressurised. So, in theory, a water-based hydraulic circuit could deliver equal mechanical output to an oil-powered alternative if the system pressure was comparable and the flow rate sufficient. However, in practice water-based systems have a lower power density in most applications, and also struggle to achieve the same operating pressure. This means that that oil-based systems generally perform better at high loads.

How water-based hydraulic systems work?

Water hydraulics operate on the same fundamental principles as traditional oil-based systems: pressure applied at one point is transmitted through the fluid to generate mechanical force elsewhere. The main difference lies in component design and fluid handling strategy.

A typical water hydraulic circuit may include:

• Stainless steel pumps, pipe clamps, diverter valves, and cylinder components designed to reduce corrosion
• Ball valves and control valves engineered for low viscosity fluids
• Additive-treated water glycol blends to improve lubrication
• High-pressure seals compatible with water glycol mixtures
• Monitoring systems to manage temperature, cavitation, and fluid quality
• Ceramic-coated plungers, pistons, and valve surfaces
• Precision-finished bores to minimise frictional losses
• In-line filtration to remove dissolved solids and corrosion debris from the fluid

Because water is less compressible than oil, response speed can be faster and positional accuracy can improve. However, materials and tolerances must be carefully selected to prevent wear under poor lubrication conditions. Some water-based systems also incorporate diverter valves to shift flow between low-pressure cooling circuits and high-pressure working circuits, allowing water to serve dual functions without additional media.

What next?

Oil-based hydraulic systems generally remain superior for high pressure and high torque workflows, and systems that require long-interval lubrication stability. However, for environmentally sensitive applications and plant used in high hygiene environments, water driven systems could be a good alternative.

The post Water-Based Hydraulics: Exploring the Shift Towards Cleaner Fluid Power Solutions appeared first on Hydrastar.

Fluid power systems in 2026 are operating under higher cumulative loads. As installed bases expand and equipment utilisation increases, the engineering challenge is shifting from specification to durability management. Recent market research projects fluid power equipment growth of approximately 6.42% compound annual growth rate (CAGR) up to 2035, indicating a decade of global system expansion. What does this mean for your maintenance planning strategy in 2026 in the coming years?

The main implication of the growth in fluid power is increasing aggregate load rates on installed systems. More operating hours mean more switching cycles through each hydraulic solenoid valve, more pressure pulses through every industrial hose assembly, and greater vibration exposure across pipe clamp support systems. In this environment, calendar-based servicing may fall short of your genuine maintenance needs. Maintenance planning in 2026 must account for duty cycle intensity, fatigue progression, and dynamic system behaviour, not just elapsed time – particularly around hydraulic solenoid valves, industrial hose, and pipe clamps.

Hydraulic Solenoid Valves: Control Points Under Load

One of the first lessons we learn in fluid power engineering is that hydraulic solenoid valves are not simple switching devices; they are critical control elements governing flow paths, actuation timing, and safety interlocks. As equipment utilisation rises, therefore, solenoid valve cycles increase proportionally, exposing coils, plungers, and seals to greater thermal and mechanical stress.

For maintenance teams, this growth translates into higher aggregate switching cycles per installed valve. Coil insulation degradation, armature sticking due to contamination, and seat wear become more probable failure modes under extended operating hours. Inspection routines in 2026 should therefore include:

• Coil resistance testing to detect thermal fatigue
• Monitoring response time deviations
• Contamination analysis in pilot circuits
• Verification of voltage stability under load

With predictable load cycles, most hydraulic solenoid valves were replaced at fixed intervals. However, under variable loads and increased utilisation, predictive maintenance and usage-based replacement is a more cost-effective strategy for businesses that want to avoid unnecessary downtime. To facilitate this, smart valve variants are now being developed that integrate sensing, electronics, and communication capabilities into the valve body or manifold — allowing them to provide diagnostic data, closed-loop control, and condition monitoring beyond basic on/off or proportional flow control functions. For example, integrated position feedback linked to a PLC control system can verify that a commanded movement equals actual movement. Deviations may indicate contamination, spool sticking, or mechanical wear, triggering a smarter replacement or maintenance cycle.

Industrial Hose: Fatigue Accumulation Under Elevated Duty Cycles

Industrial hose assemblies experience multi-axis stress: internal pressure cycling, axial tension, torsion, vibration, and external abrasion. As duty cycles increase, therefore, fatigue life – the number of stress cycles a component can withstand before failure occurs due to repeated loading – shortens non-linearly. However, the main engineering concern is stress intensity. Increased pressure pulses amplify:

• Wire braid fatigue
• Inner tube micro-cracking
• Heat-related elastomer degradation
• Coupling interface stress concentration

Maintenance planning must therefore focus on the actual stress exposure of each component, such as:

• Audit bend radius compliance under operating movement
• Inspect abrasion zones at support interfaces
• Monitor for outer cover hardening or blistering
• Measure pressure fluctuation amplitude where possible

Replacing your hose assemblies solely based on time-in-service is insufficient in high-utilisation environments. ‘Fatigue life’ is governed more by pressure amplitude, frequency, and temperature, rather than calendar age.

Pipe Clamps: Vibration Control And Load Distribution

Pipe clamps are effectively structural components within many hydraulic systems, controlling vibration amplitude and maintain alignment, and preventing the mechanical transfer of dynamic load to fittings and valve bodies. Increased machine intensity elevates vibration energy, particularly in mobile plant and high-speed automation, causing several potential defects:

• Hose chafing due to micro-movement
• Increased bending stress at coupling interfaces
• Thread loosening from vibration propagation
• Accelerated fatigue at hydraulic solenoid valve mounting points

In response, your maintenance and inspection regimen should include:

• Torque verification of clamp fasteners
• Inspection of elastomer insert condition
• Review of clamp spacing relative to line diameter and pressure class
• Assessment of dynamic loading in high-vibration zones

Where vibration amplitudes exceed the design assumptions, upgrading clamp configuration or adding intermediate supports may significantly extend your hose and fitting life.

The post Rising Demand in Fluid Power: What It Means for Your Maintenance Planning in 2026 appeared first on Hydrastar.

Hydraulic systems should always be initiated under controlled conditions, with clean oil, predictable valve positions, and secure line routing. Skipping essential checks may increase the risk of contaminants circulating around your hydraulic fluid, as well as cavitation and overheating. Fortunately, a structured pre-start procedure prevents most start-up-related damage before it can occur. Read on to find out more.

Step one: confirm oil level and condition before engaging the pump

Check the reservoir and verify that the fluid is still within the recommended fill range. If not, top it up. Next, inspect the fluid for clarity, colour, and odour. Dark, cloudy-looking or metallic-smelling oil could indicate contamination, water ingress or oxidation, which could damage your system. If the contamination is visible to the naked eye, it will already be at a harmful level. For mild to moderate contamination, run an off-line/kidney loop filtration process to clean the fluid, or increase the filter rating (lower micron) if swarf or other metallic debris is present. However, if the fluid has turned acidic, or large metallic particles are found, you may require a full system flush to remove trapped debris from your hoses, valves, cylinders, and pipework.

Step two: check filtration status and differential pressure indicators

Your filters protect the system most during the initial circulation of fluid, where settled debris becomes mobile, so if the filter is already partially blocked, it may bypass or fail to catch the debris; pushing contamination directly into the actuators, pumps, and valves. Check the differential pressure gauges or clog indicators: an elevated reading means that the element is nearing restriction. If the filter is close to its limit or overdue for replacement, we recommend changing it before the first pressurised cycle.

Step three: inspect the hoses, lines, and connections

Visually inspect the system for surface wear, cracking, or blistering along your hose runs, making sure that all hydraulic hose fittings are tight, undamaged, and fully supported to prevent vibrations. Line failure under load is often preceded by small signs, and start-up is your best chance to catch them early.

Step four: verify all valves in their correct start-up position

The relief, flow, and directional valves must return to neutral or their designated safe start position. Incorrect configuration – e.g. a mis-set relief or fully closed Webtec valve – may restrict flow and generate dangerous pressure spikes. This makes valve position one of the most critical pre-start checks.

Step five: bleed air where necessary and stabilise system pressure

Systems that have been idle, serviced, or drained often contain unwanted air pockets. This is a problem because air, like any fluid, compresses under load, potentially causing unstable pressure and cavitation. During warmup, therefore, use diagnostic equipment or manual bleed points to purge the air gradually. Pressure should rise smoothly; any pulsing or ‘sponginess’ suggests that there is still air in the system.

Step six: confirm pump rotation, alignment, and coupling condition

We recommend starting in ‘jog mode’ to verify rotation direction – i.e. that the pump shaft and motor are aligned along the same plane. This allows power to transfer smoothly without side-loading the bearings. When the alignment is correct, the system will build pressure with less friction and less mechanical stress during start-up, improving efficiency. Misalignments or loose couplings, on the other hand, can create excess vibrations and heat, putting the bearings and shafts under strain.

Step seven: apply load gradually

Once circulation begins, it’s important to increase system pressure gradually, in stages. Do not accelerate to full pressure instantly. Instead, allow the fluid viscosity to stabilise, the filters to settle, and heat to distribute evenly. This gradual rise is especially important in systems that use brake cylinders, where sudden pressurisation may cause shock loading or unpredictable movements.

The post 7 Things to Check Before Starting a Hydraulic System appeared first on Hydrastar.

The fluid power sector may be built on pressure, flow, and mechanical strength, but its future is likely to be driven as much by efficiency, data assets, and smarter design. As we move into 2026, we look at three emerging trends that reflect where hydraulic design and applications could be heading. Each one contributes to longer service life, more predictable maintenance cycles, and better energy use in industrial and mobile machinery.

1) Condition monitoring becomes standard practice

Fluid power systems have historically been serviced on a fixed schedule, with faults identified only after performance decline or failure. However, modern condition-monitoring technology is changing this approach. Engineers now have access to a wider range of operational data, allowing emerging issues to be identified at an earlier stage and resolved before they lead to downtime. Condition monitoring generally involves smart sensors installed at strategic points, such as your return lines, filter housings, actuator ports, and pump outlets, where performance anomalies are most indicative of wear.

These sensors track variables such as pressure and flow deviations, thermal loading and oil temperature, duty cycle behaviour under varying load, and even contamination levels within the hydraulic fluid. Using this information, your engineers can detect increased restriction, pump fatigue, or valve damage before any external symptoms appear. When combined with integrated filtration analytics (from market leaders such as MP Filtri), maintenance becomes evidence-based rather than standardised, extending component lives and leading to safer systems. This trend is expected to accelerate throughout 2026 as monitoring hardware becomes more compact, affordable, and widely adopted in OEM system design.

2) More efficient system architecture and component weight reduction

Space and energy consumption are perennial concerns in fixed plant and mobile hydraulic applications, but materials science and design engineering have not always managed keep pace with the performance requirements of manufacturers. Recent advantages have changed this landscape, however. Many manufacturers are now putting out smaller form components, optimising flow paths, and reducing mass without having to compromise strength or pressure rating. For example, some compact valve assemblies, engineered from composites or lightweight alloys, have both a smaller footprint than earlier generation components and higher-pressure capability. Advances in hydraulic fittings and hose technology now allow tighter installation radii, lower permeation rates, and better temperature stability – enabling more efficient circuit designs. Similar improvement in hydraulic cylinder metallurgy and seal compounds are enabling higher duty cycles with less heat loss, and a lower leakage risk. This is a positive direction of travel, with future systems promising to deliver equal or greater performance using less energy and material.

3) Greater automation in testing, commissioning, and verification

Commissioning and troubleshooting have traditionally relied heavily on engineer experience, with performance verified manually through portable gauges or flowmeters. Make no mistake, expertise will play a central role in 2026 as it always has. However, automation technologies are improving consistency, accuracy, and recordability at all stages of the process, supporting engineers to make better diagnoses, and improving warranty traceability. Software-assisted commissioning and performance sign off saves valuable time and money at the implementation stage, with notable effects on safety and performance. Some of the latest testing approaches also involve standardised test point integrated during the system build, and digital data logging that allows extended performance reviews throughout the system’s service life.

The outlook for 2026

The new technologies shaping the fluid power sector are not so much a replacement of what has traditionally worked, but an advance in how these systems perform. It’s an interesting crossroads point for hydraulic design, with fluid systems becoming more predictable, sustainable, and cost efficient.

The post Hydraulics in 2026: 3 Emerging Trends Shaping the Next Generation of Fluid Power appeared first on Hydrastar.

Hydraulic and pneumatic systems power some of the world’s most demanding industrial processes; lifting, clamping, driving, pressing, excavating and positioning with force beyond what mechanical drives alone could deliver. And as the economy strives toward net zero goals, fluid power is more important than ever, with applications being redesigned and reshaped to be leaner, cleaner, and produce more power from the same footprint.

‘Sustainable fluid power engineering’ seeks to maximise the power a system can deliver, but also to do so in the most efficient way, and at the least environmental cost. In this article, we look at how fluid power technology is adapting to meet these aspirations.

1) Energy-responsive control for reduced power consumption

Traditional fluid power systems often ran continuously at fixed pressure, regardless of the load requirements. This gave operators performance headroom, at the expense of consuming energy unnecessarily during idle or partial-duty operations. More efficient systems can now adjust their flow and pressure according to demand. For example, variable speed pump drives are increasingly replacing constant speed motors, and some pneumatic systems have flow optimisation valves to reduce air wastage. Measurement and verification tools, such as digital pressure gauges, also make performance changes more visible to engineers, allowing operators to quantify their energy savings rather than assume them.

2) Cleaner hydraulic fluids for lower environmental risk

Fluid loss and leakage is a significant sustainability concern in hydraulic systems. Even a minor leak of certain fluids can contaminate the surrounding ecosystems and water sources should it escape, as well as increasing wear on the system itself. The industry is responding to this challenge in several ways, including:

• Higher quality lubricants with longer service intervals: engineered oils and synthetics, such as Fuchs lubricants, provide better thermal stability and oxidation resistance, allowing systems to run longer between changes, and generating less waste throughout their life-cycle.
• Non-toxic and biodegradable fluids: these fluids reduce ecological risk in applications where leaks are difficult to contain, minimising environmental harm in construction, offshore, mining, and farming environments.

3) Lightweight components and efficient materials

Reducing component mass is an effective way of lowering the net energy use of mobile platforms, as well as reducing the carbon footprint associated with manufacturing. Recent developments include aluminium manifold blocks and compact cylinder housings, as well as lightweight seals and valve bodies. Efficient routing also plays a role. Modern hydraulic hose fittings with improved flow geometry reduce the pressure drop across the circuit, helping systems deliver the same output using less energy. Even marginal efficiency savings can scale significantly across large fleets, factories, and continuous-duty applications.

4) Regenerative and hybrid power strategies

Regeneration, the process of capturing energy instead of dissipating it, is becoming an important driver of sustainable actuation. In hydraulic applications, this often involves accumulator-based energy recovery, in which the excess force or fluid movement is stored and reused rather than throttled through a relief valve. Pneumatic systems can achieve a similar effect using exhaust air recapture loops that allow compressed air to be recycled rather than vented. Hybrid electric/hydraulic drives are also gaining in popularity, particularly in variable load applications where power demand fluctuates. This allows the system to draw energy only when needed. In heavy plant such as excavators and cranes, regeneration can even be applied to downforce recovery, using the weight of the machine itself to re-pressurise fluid power circuits and feed the stored energy back into the system.

5) Designing for full life-cycle value

Designing fluid power systems for a longer service life is becoming just as important as improving day to day working efficiency, because extending the life of equipment reduces material usage, replacement frequency, and its overall environmental impact. This shift is driving the adoption of more durable seals, for example, as well as higher quality hydraulic hose fittings and advanced surface treatments that resist wear over long duty cycles. Contamination control is another major factor: in-line and off-line filtration systems help to maintain fluid integrity, reducing abrasive damage and slowing down the rate of component fatigue. By prioritising longevity over peak output alone, modern hydraulic power design directly contributes to weight reduction, greater resource efficiency, and a more sustainable industrial life-cycle.

The post Fluid Power for a Low-Carbon Future: How Hydraulics and Pneumatics Are Evolving for Net-Zero Systems appeared first on Hydrastar.

To minimise or avoid unexpected downtime, it’s important to keep hydraulic systems operating at peak performance. ‘Peak performance’ doesn’t mean going hell for leather all of the time, but ensuring that the right processes are in place for all parts of the system to work optimally and smoothly. Not only does this prevent sudden disruptions to your operation, but can also extend component life, and increase safety across your plant and machinery environment.

In this article, we look at four core maintenance principles that can help you diagnose issues at an earlier stage, protect equipment, and avoid downtime.

1) Maintain clean hydraulic fluid to reduce wear and failure risk

Fluid contamination is one of the leading causes of hydraulic failure. This is because microscopic particles in hydraulic oil can accelerate friction-related wear and tear on pumps, valves, and fittings, particularly under high working pressures. Maintaining fluid cleanliness is, therefore, a critical requirement for long-term system reliability.

Using a high-quality filtration solution, such as the MP Filtri range, gives your engineers a proactive method of removing dirt, water, and sludge from hydraulic fluid. This helps maintain fluid integrity, reduce varnish formation, and protect your systems against premature component fatigue.

Key actions:

• Regularly inspect and replace your filter elements
• Track ISO cleanliness levels based on your equipment requirements
• Use return-line, pressure-line, or off-line filtration, depending on your application
• Sample your hydraulic oil regularly to detect degradation before failure occurs.

2) Monitor hydraulic pressure to identify issues before downtime occurs

Fluid power systems are designed to operate within consistent parameters, so unexpected pressure fluctuations should never be ignored. This is often one of the first signs of impending pump wear, valve damage, or seal deterioration. Accurately logging the system’s pressure ratings during routine inspections will let your engineers detect abnormalities before they develop into critical issues. Pressure gauges, compared with diagnostic access points, make ongoing monitoring relatively straightforward. When used as part of a routine maintenance schedule, they establish an objective performance benchmark from which deviations are easily recognised.

Key actions:

• Install pressure gauges at high value test points
• Compare your readings with system design tolerances
• Investigate abnormal pressure shifts immediately – don’t wait for the next maintenance cycle
• Consider using Webtec flow meters for advanced diagnostic insights

3) Use Minimess test hoses for controlled condition monitoring

Keeping track of performance on a live system can be challenging without the appropriate interface. Minimess test hoses give you a controlled and secure connection between hydraulic circuits and diagnostic instruments, enabling you to sample oil, bleed air, conduct pressure checks, or analyse system condition without having to power down. Their compact form also makes them perfect for installing on mobile plant.

Key actions:

• Fit Minimess points during commissioning or retrofitting
• Use the components with gauges, loggers, and sampling kits for full visibility
• Verify the thread, seal, and pressure specification before selection (or contact one of our technical sales team if unsure)
• Inspect your assemblies routinely for hose wear or abrasion

4) Create a preventative maintenance schedule

If you haven’t already, it’s worthwhile implementing a bespoke preventative maintenance schedule for each hydraulic system. Unplanned breakdowns always reduce productivity, and often increase your lifetime repair costs too, making a strategic maintenance programme one of the most effective ways to reduce downtime.

A good maintenance schedule should include:

• Regular fluid sampling and MP Filtri element replacement
• Pressure and performance testing
• Flow validation with Webtec flow meters or another suitable component
• Joint inspection of piping, hoses and air brake couplings
• Lubrication and alignment checks where applicable
• Preventive replacement of seals, hoses and fittings before failure

What next?

Ultimately, hydraulic reliability depends on proactive maintenance, not reactive repair. Routine monitoring using Minimess test hoses, pressure gauges, filtration solutions, and additional diagnostic tools helps maintain a safe, continuous operation while minimising downtime. Supporting components such as Gates crimp fittings, air brake couplings, and Webtec flow meters also strengthen overall system efficiency when correctly specified and maintained.

All hydraulic systems are built to deliver power, but performance ability comes from how efficiently this power is used. When a hydraulic circuit runs efficiently, with minimal restriction and manageable heat levels, you get more power output from the same energy input. When it doesn’t, even a well-designed system can consume excess power, waste fluid and wear components faster than expected. Such a system is inefficient compared to one that generates less waste.

The best way to maximise efficiency is to design efficient processes into the system from the outset. However, with the right adjustments, any system can be made more efficient. For example, it is often possible to reduce a system’s energy consumption, improve its response speed, or extend the working life of valves, actuators, and hose assemblies.

In this article, we discuss five ways to optimise hydraulic performance, helping your systems run cleaner, cooler, and more reliably.

1) Improve your flow path design

Every restriction in a hydraulic circuit – such as a sharp bend, undersized hose, or inefficient connector – forces the pump to work harder for the same result. Optimising the route layout between valves, pumps, and actuators therefore helps to improve flow velocity and reduce turbulence. In applications where frequent line disconnections are required, using a quick release coupling with low resistance internal geometry can maintain flow efficiency without sacrificing ease of access.

2) Specify the right sized pump

Not many designers undersize their pump so there is too little power to drive their application, but oversizing is a common problem. Unfortunately, oversized pumps increase relief valve cycling, generate more waste heat, and demand more power than necessary simply to operate. By sizing your pumps to the average load instead of peak load, the system will consume less energy without compromising performance. Variable displacement units provide further efficiency gains by adjusting to changing system conditions in real time.

3) Keep your oil clean

Over time, hydraulic oil accumulates various contaminants drawn from atmospheric dust, leftover swarf from machining, dirt, grease particles, and everything in between. These contaminants increase friction inside the pump, valves, and brake cylinders, wasting energy and accelerating wear. The way to avoid this is simply to keep the hydraulic oil clean and free of contamination, such as by replacing filters on schedule and monitoring the oil condition. Clean oil also reduces the risk of internal leaks – the leading cause of premature component failure.

4) Control leakage

Internal leaks are bad news in any hydraulic system, but controlling them is easier said than done. While some fluid bypass is normal, excessive leakage lowers the actuator output and forces the pump to compensate, thereby expending more energy. The best way to control leakage is by using high quality seals and reliable hose assemblies, such as Gates fittings. Not only is the damage associated with leaks reduced, but your long-term energy overheads are lowered, too.

5) Use the appropriate viscosity fluid

Choosing the appropriate viscosity for your application is a tricky design question. Lower viscosity fluids reduce the energy needed to move oil through the system, particularly in cold start conditions. However, the viscosity must remain high enough to maintain film strength and lubrication. A widely accepted rule of thumb for hydraulic fluid viscosity is to choose a fluid thin enough to flow easily when cold, but thick enough to maintain an oil film under maximum operating temperatures in load. Getting this right reduces flow resistance within the system and prevents efficiency loss, while also protecting against wear.

Next steps

Incremental improvements can scale quickly in a hydraulic application, so that a single change in routing, filtration, or fluid viscosity can significantly reduce your lifetime energy usage over thousands of cycles, delivering long-term savings with no loss of capability.
