AHP Range

The Hi-Force AHP series of air driven hydrostatic pressure testing pumps offers a choice of eight models with output pressure capacities ranging from 87 psi (6 bar) to 42500 psi (2931 bar). All models are suitable for use with various fluids, including water and are supplied with a 6” diameter glycerin filled hydraulic pressure gauge (calibrated on request), inlet airline filter, lubricator and pressure regulator unit, lightweight fluid reservoir, pump start/stop valve and a robust stainless steel skid mounted framework. Optional extras include stainless steel reservoir, stroke counter system and pressure isolation valve.

  • Output pressures up to 42500 psi
  • Suitable for use with various fluids
  • 6" dual scale vibra pressure gauge
  • Infinitely variable output pressure and fluid displacement speed
  • Airline regulator for easy setting of input air and output hydraulic pressure
  • Maximum air consumption 28 scfm (0.79 m3 / minute) at 7 bar
  • 2 gallons reservoir capacity
