For almost 40 years, Hydro-Pac has designed and manufactured a complete line of high-pressure liquid pumps and gas compressors. If you are looking for a pump or compressor to incorporate into your system; we can help. If you want a turn-key system with compressors, PLC based controls, valves and piping; we can help. If you need a one-of-a-kind pump, gas compressors or system; we can help with that too. We welcome the chance to work with you on your application.


Compressors for supply of clean, high-pressure hydrogen gas. Units available for discharge pressures of 1,000 to 20,000 psi (7 to 140 MPa). Higher pressure units also available.

Compressors and compressor systems for argon, helium and gas mixtures. Discharge pressures up 20,000 psi (140 MPa). Systems include PLC control, gas storage, valves and piping.

Production and laboratory scale compressors. Discharge pressures of 10,000 to 60,000 psi (70 to 420 MPa).

Reliable, low-maintenance, hydraulically driven compressors for supply of nitrogen gas. Units available for discharge pressures of 1,500 to 10,000 psi (10 to 70 MPa).

Gas compressors and systems to fill stationary storage and gas cylinders. Gases include argon, nitrogen, helium and hydrogen. Units used to recover boil-off from cryogenic storage.

Production and laboratory scale high-pressure pumps. Discharge pressures of 10,000 to 100,000 psi (70 to 700 MPa). Units available for various process fluids. Units for W.I.P. also.

Pumps, compressors and turnkey systems for pressure testing applications. Including autofrettage, fatigue testing, hydrostatic testing, impulse testing and pnematic leak testing.

High-pressure gas compressors for CO2 and nitrogen supply.

Custom made high-pressure pumps. Abrasion resistant, all stainless steel wet end components. Discharge pressures of 10,000 to 45,000 psi (70 to 300 MPa).

Hydro-Pac designs and manufactures custom equipment for special applications. Examples include light weight intensifiers, subsea intensifiers and on-board units.
