The unique Harben radial piston diaphragm pumps are the best performing and most reliable high-pressure diaphragm pumps on the market today. Harben pumps offer many benefits across different applications and industries. These include;

• Unrivalled reliability and low running costs
• The 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 radial piston diaphragm pump features a multi-cylinder design and can operate at speeds up to 1,300 rpm; this ensures pulsation-free operation. Its tubular diaphragm pumping chambers are ideally suited to high pressures, and the seal-less pistons never require repacking.

All the moving parts are immersed in hydraulic oil; moving parts in contact with the pumped media are limited to the diaphragm, inlet, and delivery valves. This gives the Harben radial piston pump has the unique ability to run dry without damage.

This pump design means fluids filtered to only 150 microns can be successfully pumped, whereas conventional plunger pumps require filtration to 50 microns.

Our Harben high-pressure pumps are used in numerous applications where their unique operating advantages have earned them an enviable reputation for reliability.

Some of these applications include:

• drain jetting
• cable duct desilting
• hydrostatic testing
• umbilical flushing
• water blasting
• water hydraulic systems
