Star Manifold Mounting Hand 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 valves. Designed to mount in your manifold block in a standard SAE O-ring port, they eliminate the need for a costly valve body. The lever socket is free to rotate 360º allowing the pump to be operated from any position around the axial centerline.

These pumps, either base or flange mounted style, have only check valves. They have no reservoirs, overload relief, or release valves, and are used on equipment that has its own reservoir and control valves. These pumps provide a low cost efficient means for manually developing or increasing pressure in a hydraulic system. In emergencies they furnish reliable hydraulic power to operate presses, valves, doors, safety locks and other devices.

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 foot operated model has a release pedal. 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.

Pumps oil when lever is moved in either direction Compact size Lightweight Wetted parts are of aluminum, bronze, and stainless steel: can be used with water 100% O-ring seals: locally available Pistons are ground stainless steel, hard chrome plated Leak proof O-ring ports Mounts on horizontal or vertical surface 24" operating lever included This double acting pump delivers oil when the pump lever is moved in either direction. This feature provides a more even flow of oil than a single acting pump, which delivers oil in one direction of the lever travel.
