Less Integral Reservoir

The hydraulic pump is a non-submerged vane-type design. The housing and internal parts are separate from the reservoir and are not submerged in fluid.
There are two bore openings at the rear of the pump housing. The larger opening contains the cam ring, pressure plate, thrust plate, rotor and vane assembly, and end plate. The smaller opening contains the pressure line union, flow control valve and spring. the pressure relief valve inside the flow control valve limits pump pressure.
