Pumps in this series are used to develop hydraulic fluid flow for the operation of Mobile equipment. The positive
displacement pumping cartridges are of the rotary vane type with shaft side loads hydraulically balanced. The flow
rate depends on the pump size and the speed at which it is driven.
All units are designed so that the direction of rotation, pumping capacity and port positions can be readily changed
to suit particular applications.

1. Basic Pumps: The pump illustrated in Figure 1 is representative of all double pumps in this series. The pump
consists principally of an inlet housing, two outlet bodies, a drive shaft and two pumping cartridges. The
principal components of a cartridge are an elliptical cam ring, a slotted rotor splined to the drive shaft, an inlet
and outlet support plate fitted with four special seal pack subassemblies, two flex side plates, and ten vanes
and inserts fitted to the rotor slots. Fluid enters the cartridge through the inlet port and is discharged through
the outlet of flex side plate and support plate to the outlet ports.
