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.
