Hand Operated Hydraulic Pumps - CPS-LR, CPS-PL, CP-LR & CP-PL Series without Reservoirs

With Adjustable Overload Relief Valve
With Manual Pressure Release Valve
Without Reservoir

These 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.
