Pressure intensifiers

SITEC Pressure generators for simple and easy generation of high pressures in liquids and gases

Pressure max. 10.000 bar

Features and advantages

  • Simple and easy generation of highest pressures in liquids and gasses
  • Used for pressure testing and autofrettaging of pressure vessels, valves, tubings, fittings and complete systems.
  • In process engineering for the pressure generation in reactors, pressure vessels and isostatic com paction systems.
  • Intensifiers are manufactured in two basic models for producing pressures up to 7,000 bar (100,000 PSI) and 10,000 bar (150,000 PSI).
  • Reliability and safety with optimum stress distribution in the high-pressure cylinder.
  • The intensifier consists of a stepped-piston-cylinder arrangement with a fixed intensifier ratio of 1:16.
  • The low-pressure fluid is pumped into the large cylinder expelling the fluid from the small cylinder at a higher pressure, depending on the area ratio and friction.
  • Sturdy design and minimum wear at highest pressures.
  • External piston position indicator.
  • Safe operation with Bridgman high-pressure closures on the dynamic and static packings.
  • Material: Stainless steel 17-4 PH.
  • Intensifier systems: For each pressure range three typical models are available for gases and liquids.


  • Custom-made designs available on request.
