11. Installation 11.1 Mounting
The gure below illustrates how to mount the
pump and connect it to electric motor/combus-
tion engine.
A: Flexible coupling
B: Bell housing
C: Motor shaft
If alternative mounting is required, please
contact Danfoss Sales Organization for further
information.
To ensure easy mounting of the exible coupling
without using tools, the tolerances must be
dimensioned accordingly.
Note: Any axial and/or radial loads on the shaft
must be avoided.
The pump should be connected to the rest of the
plant with exible hoses.

11.2 Open-ended system with direct water
supply
In order to eliminate the risk of cavitation, a
positive inlet pressure is always to be main-
tained. Please see technical data (part 3.) for
specic pressure values.
1. Place the lter (1) in the water supply line in
front of the pump.
2. Place a monitoring pressure switch (2) - set
at min. inlet pressure - between lter and
pump inlet. The monitoring switch must
stop the pump at pressures lower than min.
inlet pressure. Please see technical data
(part 3.) for specic pressure values.
11.3 RO system with APP pump
1. Dimension the inlet line to obtain mini-
mum pressure loss (large ow, minimum
pipe length, minimum number of bends/
connections and ttings with small
pressure losses).
2. Place an inlet lter (1) in front of the APP
pump (2). Please consult section 9,
“Filtration” for guidance on how to select
the right lter. Thoroughly clean pipes and
ush system prior to start-up.
3. Place a monitoring pressure switch (3) set
at min. inlet pressure between lter and
pump inlet. The monitoring switch must
stop the pump at pressures lower than
minimum pressure.
4. Use exible hoses (4) to minimize vibrations
and noise.
5. In order to eliminate the risk of damage
and cavitation, a positive pressure at the
inlet (5) is always to be maintained at min.
inlet pressure and max. inlet pressure.
6. For easy system bleeding and ushing, a
bypass non-return valve (6) is integrated in
the APP pump.
7. A non-return valve (7) in outlet can be
installed in order to avoid backspin of the
pump. The volume of water in the
membrane vessel works as an accumulator
and will send ow backwards in case of the
pump stops momentarily.
8. A safety valve (8) can be installed in order
to avoid system damage as the Danfoss
APP pump creates pressure and ow
immediately after start-up, regardless of
any counter-pressure.
