The unique Harben® radial piston diaphragm range of pumps are the best performing and most reliable high pressure pumps on the market today. Harben® pumps offer many benefits across different applications including the oil and gas industry, aerospace and drain and sewer cleaning:

  • Unrivalled reliability and low running costs
  • Pump can run dry without damage
  • Filtration to 150 microns
  • Pumps low lubricity fluids with ease
  • Has multi-cylinders therefore minimal pulsation
  • Unequalled continuous running capabilities
  • Compact and lightweight
  • Simple to pressure compensate

The Harben® high pressure pumps feature multi-cylinder design ensuring pulsation free operation, tubular diaphragm pumping chambers eliminating piston seals, all moving mechanical parts immersed in hydraulic oil bath – moving parts in contact with the pumped media are limited to the diaphragm, inlet and delivery valves. The nature of the pumps design allows the use of “dirty” water, filtered to only 150 microns, whereas conventional plunger pumps need filtering to 50 microns, and gives the ability to run dry without damage.
