Cold isostatic pressing (C.I.P.) is a high-pressure manufacturing process used to compact metal, plastic, composite or ceramic powders uniformly. C.I.P. parts are enclosed in a flexible, sealed container and immersed in a pressure vessel filled with a liquid at ambient temperature.

Our experience includes manufacturing pumps, valve racks and high-pressure vessels at pressure ranges from 10,000 to 60,000 psig (69 to 414 MPa). The process liquid is typically a non-corrosive water and soluble oil mixture. However some C.I.P. applications, such as food C.I.P. use water. Hydro-Pac pumps can be offered for both non-corrosive fluids and water.



  • Robust, reliable, low-maintenance design.
  • FC-SERIES pumps for productions class applications.
  • Li’l Critter™ pumps for laboratory usage and test applications.
  • Standard FC-SERIES and Li’l Critter™ pumps are double ended intensifiers with electro-hydraulic power units.
  • Double ended pumps are typically used for filling large volumes.
  • Single shot pumps used for smaller volumes. Single shot pumps eliminate the requirement and cost of let down valves.
  • Custom control and piping systems can be quoted for any machine.
  • Standard operating ranges for this line are:
  • Discharge pressures: 10,000 to 200,000 psig (70 to 1400 MPa)
  • Frame sizes: 10 to 200 HP (7.5 to 150 kW)
  • Non-corrosive fluids with options for water and other fluids.
  • The FC-SERIES pumps are production class units and is ideal for high pressure, larger flowrate applications.
  • Standard operating ranges for this line are:
  • Discharge pressures: 10,000 to 100,000 psig
  • Frame sizes: 3 to 5 HP (2.3 to 3.8 kW)
  • The Li’l Critter™ is ideal for small scale production and test applications
  • Standard discharge pressures: 10,000 to 30,000 psig
  • Standard ID: 6 to 52 inches (152 to 1321 mm)
  • Closure types: Full thread, breach thread (quarter turn) and pin.
  • Designs: Monobloc, Tie-rod, Multi-Wall and other special designs.
  • Codes: ASME section VIII, Division 1, 2, or 3; PED (Europe); KHK (Japan); or non-code designs.
  • Machined from forgings or bar stock.
  • Speciality vessel designs
