Choosing a new pump for your hydraulic system can be confusing, with many options from which to choose, including; pump size, flow rate, hose inlet and outlet sizes. Selecting the wrong pump could lead to a poorly performing hydraulic system, premature wear of components, and endless hours to carry out repairs and upgrades while the system is out of action. So, when choosing a hydraulic pump, what are the main considerations?
If you have spare hydraulic cylinders that you need to store, it’s important that they remain in optimum condition and don’t deteriorate over time. Failing to prepare the cylinders correctly for storage, or storing them in inappropriate conditions, can be an expensive mistake; they may not function properly later and will probably need to be replaced.
In engineering, fluids (whether liquids/hydraulic, or gases/pneumatic) play a significant role in the design and construction of systems and machines. The study of fluids enables engineering applications in a variety of designs and structures, ranging from medical equipment to irrigation systems. Hydraulics and pneumatics focus on the mechanical qualities of liquids and gases respectively. How to decide the type of system most suited to your application at the design stage?
Every powered hydraulic machine generates ambient heat. Heat dissipates throughout the system, creating a broadly equivalent level temperature. It’s both a benefit and a hazard to engineers and designers working with volatile, sensitive mechanical systems. While the wasted thermal energy from moving hydraulics helps prevent freezing, rusting, and jams, hydraulic warmth also needs to be safely and quickly dissipated away when the machine’s fluid loop is deactivated.
Hydraulic systems use pressurised fluid to operate arms and pistons with extraordinary strength. While that’s great for industry and manufacturing, we shouldn’t forget their many other uses, too. One often-overlooked application is as a driving force for industrial-strength motors.
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.
Hydraulics offer excellent directional power and control when it comes to lifting, moving, and excavating heavy loads. However, hydraulic systems can also be highly dangerous if used incorrectly or handled carelessly.
Accidents, serious injury, or death can result from maintenance and tasks going wrong. This isn’t always the fault of an arm, or boom failure, or load drop – the fluid and mechanical parts used in hydraulics can also malfunction and break. Here’s a quick guide to the most common hydraulic faults and risks, and what you can do to avoid and limit them. Continue reading “What NOT To Do When Working On Hydraulics”
Hydraulic and pneumatic systems both use kinetic motion to move heavy loads. Hydraulics use confined water or oil, and pneumatics use a confined gas, typically air, to generate kinetic motion to drive cylinders and rams. Motion and pressure are converted and multiplied through confinement and precise direction into an intense push.
While the two processes may appear very similar, there are several important differences in how they operate in practice and the tasks they can be used for. Continue reading “Hydraulic & Pneumatic Systems – Understanding The Similarities & Differences”
Hydraulics is the art of using contained fluid to translate a small push into a big one. Through dissipating the force provided by a smaller ‘push’ cylinder through a pipe and reservoir network, trapped kinetic energy is transferred through oil or water to a larger one.
