Pressure Compensated Hydraulics


Definition - What does Pressure Compensated Hydraulics mean?

Pressure compensated hydraulics is a technology that automatically reduces flow based on system pressure. Unlike pumps with load sensing hydraulics, pressure compensated pumps only respond to system pressure. Pressure compensation is a key concept in hydraulic systems. Hydraulic equipment is commonly used in trenchless construction operations.

Trenchlesspedia explains Pressure Compensated Hydraulics

When the pressure on a pump rises above a pre-set limit, a pressure compensated pump reduces the system flow. This prevents a pressure overload on the hydraulic system. The pressure compensator is built into the pump at the factory.

Pressure compensating reflects a type of pump control. When the pre-set pressure is reached, the pressure compensating valves starts closing the orifice, restricting flow to the system. The valve opens and closes dynamically to calibrate the system.
