APP Pump animation

Danfoss APP pumps are based on the axial piston principle offering long life and high efficiency.

The pumps are fixed displacement pumps in which the flow is proportional to the number of revolutions of the input shaft and the pump displacement, regardless of any counter-pressure.

The most compact high-pressure pump for seawater RO on the market

All parts are designed to provide long service life, i.e. long service life with a constantly high efficiency and minimum of service required.

More design options that with any other RO pump: no need for frames, belt drives or gear boxes. APP pumps can be installed horizontally and vertically. 
 
Lubrication of the moving parts in the pumps is provided by the fluid itself. No need for oil lubrication is thus required. Ever!

Wide flow range, with one APP covering the range of several centrifugal pumps.

All parts are made of Duplex or Super Duplex.

8.000 hours maintenance free operation.
