The flow is initially directed to the priority port until the priority setting is satisfied. At that time any additional flow is directed to the excess flow port. Priority divider pumps are typically used in steering circuits, brake circuits or any circuit where a primary flow needs to be satisfied first. • RELIEF VALVES Various styles and configurations of relief valves can be provided in the rear cover. The relief return flow can be either ported external to the pump or internally ported back to the inlet. Caution must be used so that the duration of the internally ported flow does not cause excessive heat build up. • CUSTOM DESIGN VALVE PACKAGES Prince Manufacturing offers custom designed integral valve packages. Configurations are developed based on customer specifications. • SOLENOID VALVES Various configurations of controlling pump flow by using solenoid cartridge valves are available. • SPECIAL REAR PORTING A wide variety of port types as well as port locations can be accommodated with the extruded rear cover. • DOUBLE PUMP CONFIGURATIONS Integral valve configurations can easily be integrated into double pump configurations. Valves in the rear cover typically control flow from the rear pump section, however valves can also be incorporated into the center section of the double pump for additional control options. • HIGH-LO PUMPS (Horse power limiting pumps) A high-lo configuration is available based on the SP20 series pump. The typical configuration provides 28 gpm low pressure flow and 7 gpm high pressure flow (at 3500 rpm). Typical horsepower requirements are 19 hp at 3000 psi and 3500 rpm.
