APP 5.1, APP 6.5, APP 7.2, APP 8.2 and APP 10.2
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 salt water pumping.
The APP pumps are based on the axial piston
principle enabling a very light and compact
design, and they are designed so 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 APP 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.
