• Single acting
  • Single air drive head
  • Pressures to 3,700 bar (53,660 psi)
  • Stainless steel body and wetted parts - which means they are optimally suited for use in water hydraulics
  • They are suitable for use in zone 1, category 2G/2D IIB TX explosion-proof areas (Temperature class depending on medium temperature).

Examples of application for the S...SS Series hydraulic pumps include:


  • Hydrostatic tests: Valves, tanks, pressure vessels, pressure switches, hoses, pipes & tubing, pressure gauges, cylinders, transducers, well casings, BOPs, gas cylinders and components from the Aerospace technology.
  • Burst and Cycle fatigue testing for parts mentioned above
  • Calibration: Pressure gauges and transducers
  • Water jet cutting and cleaning
  • Leak testing
  • Emergency shutdown systems for Oil & Gas Wells
  • Pressurisation of accumulators for testing numerous components
  • Operation and Control of well service and well head equipment

General Information
Technical Data

S...-SS Pumps


S...-SS pumps are single acting types with single air drive head. They are compact and lightweight for simple installation in both static and portable applications. They will operate at an air pressure as low as 1 bar (14.5 psi) due to minimal internal friction. S pumps are ideal for applications demanding fast response time.


  • Stainless steel bodies and plungers and polyurethane seals.
  • Pumps come standard with side inlet only
  • Ideal for portable power packs
  • For air drive pressure from 1 bar (14.5 psi) to 10 bar (145 psi) maximum.
