Topping up the hydraulic reservoir is a vital piece of routine maintenance, because – if it is not done correctly – the ramifications are severe. A sure sign of a leaking system is one that requires make-up fluid regularly. Identifying where the system is leaking and repairing it is essential, to ensure that the system runs smoothly.
Generally speaking, hydraulic oil pollutants are classed as substances that prevent the fluid from working properly. Air is one such substance, so when it finds its way into the oil, remedial action is needed to keep the fluid and other parts of the hydraulic system protected.

The UK lockdown to combat Coronavirus (COVID-19) has affected the hydraulic and pneumatics industry as much as any other. Nevertheless, there are some great, positive news stories breaking through in the world of hydraulics despite all the gloom elsewhere during the pandemic.
Here are our favorite uplifting stories about engineering, hydraulics, and pneumatics from the past few months.
Despite having been around for centuries, Hydraulic engineering is still dynamically evolving. Innovations and improvements emerge all the time. New products make hydraulic equipment smarter, smoother, and more powerful. The rise of digital technology and automation is changing the way industrial hydraulics work rapidly, too.
Here are the three emergent hydraulic trends that we’re most excited about this year.
A ball valve is a simple, two-part, chambered control valve commonly used in hydraulic, pneumatic, and liquid plumbing systems. Ball valves are used to shut off the flow of liquid or gas, adjust it to a limited level, or redirect flow on a two-forked connector (when used in conjunction with another ball valve). A ball valve is omnidirectional (and can be used as such) but is usually used to control a one-way liquid or gas flow.
A service plug is a resistant device that can be placed in an open hydraulic pipeline or chamber inlet or outlet to stop leaks, spillages, and unintentional drainage. They are used when a machine has stopped and is being maintained and should never be used on a running hydraulic system, or one that is cooling after having recently been shut down.
Service plugs come in many different shapes and sizes to fit different types of hydraulic pipe and nozzle. They are usually a simple, high-resilience piece of moulded rubber shaped into a wedge, with a broad top ridge for easy removal. They’re used in industrial, plumbing, and catering machines, but are most popular for use in hydraulic control and maintenance.
A leak from a hydraulic hose spells danger. The highly pressured liquids used in hydraulic systems can pose a significant risk to personnel and property in the workplace, producing spillages that can cause slips and falls, creating a fire danger that could be potentially devastating. Chemical or corrosive liquids can cause life-changing injuries, such as severe burns, damage to eyesight or impaired breathing, and may also be carcinogenic.
Fortunately, leaking hoses are easy to spot, but administering repairs, as well as cleaning up spilled hydraulic fluids, is time-consuming and logistically difficult. Repairing damaged or worn hoses also means taking equipment out of service, affecting production and damaging profitability. As with many problems in industry, prevention – rather than the cure – is the best answer. Continue reading “How To Prevent Dangerous Leaks In Hydraulic Hoses”
High quality hose assemblies are vital for the efficient and safe operation of hydraulic machinery. Incorrect hose assembly increases the potential for components to separate under extreme pressure, spraying hot fluid around the working environment. At the very least, this causes disruption to the production line while equipment is taken out of service and hydraulic fluid is cleaned up. In the worst case scenario, line operatives may be severely injured by hot or corrosive fluid, or hose whips.
Hydrastar supplies the full range of Gates crimping equipment to help you create robust and safe hose assemblies for your production line and minimise the possibility of hose lines separating – and the Gates eCrimp app will make your workshop even more efficient. Continue reading “What Is E-Crimp?”
If you’re assembling hydraulic equipment, or need to upgrade components in an existing system, you must use high quality, durable and reliable hydraulic fittings. Components need to withstand excesses of pressure and temperature and any failure in the system could cause potentially catastrophic results, leading to damage to the equipment and serious injury to operators.
Consequently, it is important to have absolute confidence in the hydraulic fittings you use so you can contain, control and direct the flow of the hydraulic pressure while guaranteeing consistent and reliable service. Continue reading “Where Can I Buy Reliable Hydraulic Tube Fittings?”
In any hydraulic machine, the hoses are key components. While the pumps, actuators, valves, and fluid mechanisms are also central parts of the machinery, they would be unable to perform their roles without appropriate and operational hydraulic hoses. Hoses must be selected correctly because they should be durable enough to tolerate extremes of temperature and strong enough to withstand the movements of highly pressured fluids.
Hoses that are incorrectly chosen are liable to premature failure, which can damage equipment, cause extensive delays to the manufacturing process and inflict serious injury on machinery operatives.
When selecting the correct hydraulic hose for your machinery, make sure you consider these key factors: Continue reading “How To Select The Right Hydraulic Hose For Your Application”
