Berarma 01 PHPK 2-50 Pump - 01 Phpk 2 50 Pump

PHPK pumps are high pressure variable displacement vane pumps equipped with hydraulic horse power limiter device that allow you to instantly adjust the flow rate accordingly to circuit requirements.

Variable displacement vane pumps are volumetric type so they deliver a maximum flow rate equivalent to its displacement for their speed of rotation. Operating pressure is due to pressure loads encountered by the fluid within the system.

When this value is achieved, pump reduces its flow rate to zero, keeping the pressure almost constant. In zero flow conditions, pump delivers oil only to compensate any possible drain and piloting. In addition, the horse power limiter device allows to optimize power consumption.

The operating principle is based on maintaining the flow-pressure product (q x p) practically constant, so that when the pressure increases, the flow decreases and vice versa, according to a characteristic hyperbolic-type curve.
