AZPS Gear Pumps With Integral Valves

Short Description:

In order to reduce external pipework it is possible to incor-porate a flow-control valve or pressure-relief valve in the rear cover of the gear pump. A typical application of this is in the supply of hydraulic oil in power steering systems.

The pump delivers a constant flow irrespective of the speed at which it is driven. The excess flow is either returned internally to the suc-tion port or distributed externally to other items of equipment.
