C04 mini power packs are equipped with high pressure variable displacement vane pumps with hydraulic pressure regulating 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 the outlet pressure (on the system) equals the pump setting pressure, the flow rate is adjusted to the values required by 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.

The integration of variable displacement vane pump and hydraulic block allows to realize extremely compact and energy-saving hydraulic systems where pressure and/or flow rate controls are needed.
