Single Speed Pumps
Single - acting pumps are available with or without reservoirs and control valves.

Two Speed Pumps
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 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. The foot operated model has a release pedal. Built-in reservoirs of any size may be specified. The adjustable overload will be set at the maximum pressure at the factory unless a lower pressure is specified by the customer. The overload can be adjustedby the customer in the field, if required. Also available without reservoirs.

Manifold Mount Pumps
These pumps provide a low cost efficient means for manually developing or increasing pressure in a hydraulic system.
Whether used as the primary pump for a hydraulic system, or a standby pump for emergencies they furnish reliable hydraulic power to operate presses, valves, doors, safety locks and other devices.
They are complete pumps with suction and pressure check valves but without release and overload valve. They are made to mount in your manifold block in a standard SAE O-ring port and they eliminate the need for a costly valve body.
The handle socket is free to rotate 360° allowing the pump to be operated from any position around the axial centerline.

Stainless Steel Pumps
Star pumps with wetted parts made of brass and stainless steel are available in the following models:

P1A-LR-SC
P4A-LR-SC
SP1A-SC
SP4A-SC

The P1A-LR-SC and SP1A-SC models have one wetted brass part while the P4A-LR-SC and SP4A-SC have all wetted parts made of stainless steel. Lever handle, base plate, socket and links are not stainless steel. Select the required model.
Star will manufacture other models in stainless steel to your requirements. All models also available in 100% stainless steel.
