Pressure Compensator

Definition - What does Pressure Compensator mean?

Pressure Compensator is a device which aims to balance the internal pressure of hydraulic systems under the ambient pressure of surrounding sea water. The product is made up of high tensile strength enforced between neoprene materials. It is essential because it can prevent water intrusion due to its high pressure and can protect the internal equipment from water damage. Pressure Compensators eliminate rod seals and pistons to offer reliability. They are manufactured from hard anodized 6061-T6 aluminum and are available in diverse pressure control differentials.

Petropedia explains Pressure Compensator

Pressure Compensator offers compensated pressure while the excess oil passes over the relief valve. It is a restricted style compensator which is used to maintain the preset pressure that influences the pressure variation on the flow rate. Some of its advantages are:

  • It offers excellent dynamics
  • It offers stability overflow range and pressures
  • It minimizes the effect of eccentricities in cavity
  • It maximizes the reliability in operations

The compensator is used to unload the pump when the pressure reaches a certain level. Besides, it offers maximum mounting flexibility during cartridge construction.
