Several measuring devices can prevent damage to a hydraulic system:
  • a filter maintenance indicator
  • a water content measuring device
  • a particle counter
See our article on HYDRAULIC CIRCUIT CONTAMINATIONS to learn more.
For manual filling, make sure the oil cap is clean and that you use a dry funnel (free of water or other fluids) and free of dust or particles. The use of a filter pump to transfer oil from the gallon to the tank is a useful method of preventing contamination and ensuring the protection of the hydraulic system. See our article on HYDRAULIC CIRCUIT CONTAMINATIONS to learn more
Tests are used to determine whether or not contaminants are present. This is most often done by analyzing the viscosity, water content, or solid content. See our article on HYDRAULIC CIRCUIT CONTAMINATIONS to learn more.
To clean a contaminated hydraulic system, there are equipments which allow a depollution of the fluid in a hydraulic circuit.
  • Mobile filtration units can be connected to the circuit, allowing the fluid in the circuit to be depolluted
  • The installation of fluid purifiers is a more complete system to clean up a fluid contaminated by particles, water or gases.
  • In some major cases, a complete emptying followed by a cleaning is necessary.
See our article on HYDRAULIC CIRCUIT CONTAMINATIONS to learn more.
There is a multitude of hydraulic fittings. They are differentiated according to several criteria:
  •       Male or female connections,
  •       Straight or angled fittings,
  •       Rigid or swivel fittings.
Hydraulic fittings are available in many sizes and depending on your needs, fittings should be selected according to the type of hydraulic hose (braided, spiral, high pressure, thermoplastic or other). For more information, see the TYPES OF FITTINGS AVAILABLE from HP Hydraulics.

An open system is one where the fluid flows from the pump through the valves and back to the tank. This means that the pump provides a continuous flow to the hydraulic system. In addition, an open circuit is a one-way circuit, which means that the fluid can only flow in one direction.  On the other hand, in a closed-loop hydraulic system, the fluid from the piston pump flows directly to a motor and back to the pump without passing through the reservoir. The special feature of this type of system is its bi-directional operation.  For more explanations, see our ARTICLE ON THE DIFFERENCES BETWEEN AN OPEN AND CLOSED HYDRAULIC SYSTEM.
