Desalination Pumps
High Pressure Pumps
Superfoss develops high pressure pumps (HPP) for Seawater Reverse Osmosis (SWRO) and the Brackish Water Reverse Osmosis (BWRO) applications.The product line is based on the efficient Axial Piston Pump principle.
The pumps are designed and produced in Denmark and manufactured from Duplex and Super Duplex stainless steels ensuring a product of highest quality.
They come in 4 different sizes ranging from 4,9 m^3/h to 11,1 m^3/h at 1800 rpm. The pumps are suitable for speed regulation in the range of 650 - 1800 rpm.
Below is an overview of various speeds/flows/pressures and the recommended motor sizes.

Benefits:
The super numbers
Efficiencies up to 90%
Minimum flow resistance through the pump is achieved with a valve plate design instead of check valves. This combined with low friction sliding pairs and hydrodynamic main bearings results in a highly efficient pump.
Affordable
Using the latest developments tools and modern 5 axis machining makes the pumps affordable to buy. High efficiency and low maintenance makes them affordable to run.
Corrosion resistant
With the casing made of Duplex and internal parts made of Super Duplex stainless steel. We are confident to allow a seawater inlet temperature up to 50 °C.
Integrated flushing valve
When the pump is not running a integrated one way flushing valve allows flow from the pump inlet to the outlet.
Port connections according to ISO-6149
For minimum leakage and maximum vibration resistance. Superfoss pumps are designed with metric M42x2 thread and a o-ring seal according to ISO-6149
9 pistons and low pulsations
No need for pulsation dampers. 9 pistons have a kinematic non-uniformity grade of 1,5% compared to 14% for a 3 piston design.
Compact design and small footprint
Axial piston pumps have a high power density. With a diameter of ø178mm, length of 320mm and a weight og 35Kg, it is easy to transport and can be installed where space is limited.
Water lubricated – no oil changes
The seawater acts both as a lubricant and as a coolant. You need to prefilter your water carefully, but no need for oil changes.
Up to 1800 rpm and direct drive
The pumps have a speed range of 650 rpm to 1800 rpm. They are designed to mounted directly to the electric motor by means of a standard bellhousing and claw coupling. No need for belt drives or gearboxes.
