Hi-Q (High Pressure Diaphragm Pump)

The Harben Hi-Q high pressure diaphragm pump is capable of pressures up to 4,000 psi and flows to 25 gpm. It is available in a 4 cylinder format requiring up to 75 hp depending upon the pressure and flow configuration chosen.

Drive power can be diesel or electric and we have a range of gearbox ratios to suit all requirements5

The Hi-Q has a unique mode of operation that keeps all the moving parts inside the pump separated from the pumped fluid. The video below clearly shows the simplicity of operation which delivers some significant advantages over more traditional direct acting pumps.

  • No packings or seals to wear out
  • Pump can run dry without damage
  • Suitable for a large range of low viscosity fluids
  • Pumps low lubricity fluids with ease
  • Has multi-cylinders therefore minimal pulsation
  • High power to weight ratio
  • Simple to pressure compensate
  • Frost tolerant
