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.
