High pressure
pumps
Harben diaphragm pumps that can run dry, and Aqua and HPP triplex plunger pumps for the highest pressures — used around the world for numerous cleaning and pumping tasks.
The only pump of its kind — and it runs dry
The Harben radial piston diaphragm pump is the only such diaphragm pump available on the market today. Separating the pump’s moving parts from the fluid has massive benefits — particularly when that fluid has poor lubrication qualities, such as water.
Methanol, deionised water and most subsea control fluids present similar pumping challenges. No other high pressure pump can run dry — an advantage wherever inlet conditions cannot be guaranteed, including drawing water from header tanks.
- Runs dry — where inlet conditions can’t be guaranteed
- Poorly lubricating fluids such as water, methanol and subsea control fluids
- P Type and Century from 140 bar up to 700 bar
Honed to rugged perfection in heavy industry
A proven product whose design has been refined over many years of use in heavy industry. The Aqua is used around the world in steel mills, chemical plants and offshore, where it provides supremely reliable performance.
Maintenance is very simple, needing no specialised tools or techniques.
- Steel mills, chemical plants, offshore
- Simple maintenance — no specialised tools
- Up to 3,000 bar (43,000 psi)
A modern triplex range up to 2,800 bar
The HPP is a modern triplex plunger pump range with working pressures up to 2,800 bar.
- Tungsten carbide plungers — robust
- Forced crankcase lubrication with oil cooling
- Horizontal or vertical mounting options
