Star Hydraulics, LLC - Hand Operated Hydraulic Pumps - CP & CPS Series with Reservoirs

With Oil Reservoir
With Adjustable Overload Relief Valve
With Manual Pressure Release Valve

Star two-speed Hi-Lo 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 automatically at approximately 300 PSI. Star's unique valving allows a single 24" lever to be used for both high pressure and low pressure pumping so there is no need to interrupt pumping to move the lever to another socket. The hand operated model has a choice of screw or cam release. Built-in reservoirs of any size may be specified. 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: CPS04-80-7500)
All CP04 pumps have a unique port to handle the high pressure requirements. See the CP04 port drawing for detailed information on thie port configuration.
