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
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 pumps 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 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:
cable duct desilting
water hydraulic systems
