With Adjustable Overload Relief ValveWith Manual Pressure Release ValveWithout ReservoirThese pumps, either base or flange mounted style without oil reservoirs, are used on equipment that has its own built-in reservoir. These 2-speed pumps provide rapid movement at low pressure for the part of a cylinder's stroke where no work is encountered. The pump automatically switches to high pressure when the cylinder must deliver maximum push or pull force. Changeover from high volume-low pressure to low volume-high pressure occurs at approximately 300 PSI and is automatic-no need to shift lever or interrupt pumping. Hand operated models have a choice of screw or cam release. The adjustable overload valve will be set at the maximum pressure at the factory unless a lower pressure is specified by the customer. The overload can be adjusted by the customer in the field, if required.

Design Notes:- Factory overload will be set at maximum unless a lower pressure is specified by the customer. To specify a pressure, add to end of the part number (ex: CPS13-LR-8000)
- PL pumps do not have threaded inlet ports. They must be gasket mounted to a reservoir
- All CP04 style pumps have a unique port to handle the high pressure requirements. See the CP04 port drawing for detailed information on this port configuration.
