Data sheet APP 16-22
APP 16-22 pumps are designed to supply low
viscosity and corrosive uids under high
pressure, e.g. in seawater reverse osmosis
ltration applications and for high pressure salt
water pumping.
The pumps are based on the positive displace-
ment principle (axial piston design) which
enables 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
uid itself. No oil lubrication is thus required.
The pumps are supplied with an integrated
ushing valve that allows the salt water to ow
from inlet to the outlet, when the pump is not
running.
