Hand Pumps-Single Stage
7250 or 3000 psi max. For Single-Acting Systems. Manually-operated hydraulic power source for moderate-size fixtures. Compact and portable. Totally self-contained. Easily adjustable pressure setting. Pump and release with the same lever-choose either a knob handle for hand operation, or a rubber pedal for foot operation. Excellent service life because internal components are virtually wear-free. Hand Pumps are suitable for smaller clamping fixtures and assembly operations where automatic pressure control is not required. Hand operation is ideal when extra "feel" is required for assembly and/or test fixtures.
Operation
Turn pressure-adjustment knob to set desired operating pressure. To clamp, move pump lever downward to pump fluid, through a 40° stroke. Lever returns upward by spring force after each stroke. Repeat until you reach the set pressure, where the lever declutches. To unclamp, lift pump lever 10° upward, against spring force, to release clamping force instantly.
Mounting & Setup
Mount unit upright, using one of the three optional mounting bases. Unit is ready to operate after you fill the reservoir with clean, approved Hydraulic Fluid. Do not use NPT fittings for hydraulic connections.
