APP21 - 38 Water Pumps for Desalination

APP21 - 38 Water Pumps for Desalination

Danfoss APP 21-38 pumps are designed to supply low viscosity and corrosive fluids under high pressure, eg.in seawater reverse osmosis filtration applications and for high pressure salt water pumping.

The pumps are based on the axial piston principle enabling a very light and compact design, and they are designed so that the lubrication of the moving parts in the pumps is provided by the fluid itself. No oil lubrication is thus required.
The pumps are supplied with an integrated flushing valve that allows the salt water to flow from inlet to the outlet, when the pump is not running.
All parts included in the pumps are designed to provide long service life, i.e. long service life with a constantly high efficiency and minimum service required.
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.
