Enerpac ultra-high-pressure, hydraulic hand pumps are offered as single-stage or 2 stage manual pumps that can handle up to 40,000 psi (2800 bar). Typical industrial applications include lifting, testing, calibration, maintenance, and repair. The P2282 model provides two speed operation to reduce the number of handle strokes and is lighter than steel equivalents. The two-speed operation requires up to 78% fewer handle strokes than single-speed hydraulic hand pumps, and the handle locks into place for secure transport. The single-speed models, 11100 and 11400, are built using 303 Stainless steel construction. Ideal for use with many different fluids, such as distilled water, alcohol, diesters, silicones, soluble oils and petroleum. The 11100 model is rated up to 10,000 psi (700 bar) and the 11400 model is rated up to 40,000 psi (2800 bar) Both the single-speed and the two-speed models have a large release knob for improved control of pressure release.
