APP 1.5, APP 1.8, APP 2.2, APP 2.5, APP 3.0 and
APP 3.5 pumps are designed to supply low
viscosity and corrosive fluids under high
pressure, e.g. in seawater reverse osmosis
filtration applications and for high-pressure
saltwater pumping.
The pumps are based on the axial piston
principle enabling a very light and compact
design. The design ensures that lubrication of
the moving parts in the pumps is provided by
the fluid itself. No oil lubrication is thus required.
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 of
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, regardless of any counter- pressure.
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.

1) Typical average flow at 80 bar (1160 psi).
2) For lower pressure, please contact
Danfoss RO Sales Organization.
3) For higher pressure, please contact
Danfoss RO Sales Organzation.
4) Intermittent pressure is acceptable for less than
10 seconds per minute.
5) For speeds above 3000 rpm the pump must be
boosted at a pressure of 2-5 bar (29.0 - 72.5 psi).
