Pump PHP

Description

Berarma PHP Pumps

PHP pumps are variable-displacement vane pumps with high operating pressure and a hydraulic-type pressure regulating device that allow the flow rate delivered to be instantly adjusted according to the circuit demands.

Variable displacement vane pumps are positive displacement pumps; therefore, they deliver a maximum flow rate equivalent to its displacement times its rotational speed. The operating pressure is due to the pressure drops that the fluid encounters as it travels through the system.

When the discharge pressure (on the system) equals the set pressure of the pump, the flow rate delivered adjusts to the values required by the system; having reached this value, the pump reduces its flow rate to zero, keeping the pressure nearly constant. Under conditions of zero required flow rate, the pump delivers only oil to compensate for any leaks and piloting.
