11400 Enerpac P/11 Stainless Steel Ultra-High-Pressure Hand Pump, 40,000 psi, 45 in³, Single-Speed

11400 Enerpac P/11 Ultra-High-Pressure Hand Pump combines 303 stainless-steel construction with a 40,000 psi pressure rating. It is intended for specialized high-pressure systems where both fluid compatibility and extreme pressure capability are required.

Not a Standard 10,000 psi Hydraulic Pump

The 11-400’s pressure class changes the entire system around it. Enerpac directs ultra-high-pressure pumps to dedicated cone fittings, tubing, gauges and adapters designed for those pressures; ordinary 10,000 psi cylinder-system hardware must not be treated as interchangeable.

The pump uses single-speed operation with a small displacement per stroke at high pressure and carries 45 in³ of usable fluid. Its stainless-steel construction supports use with several compatible specialty fluids and provides strong corrosion resistance.

For stainless construction at the standard 10,000 psi range, 11-100 is the lower-pressure alternative. Select 11-400 only when the application and all connected components are specifically engineered for 40,000 psi service.
