For more information on the importance of
proper ltration, please consult our data sheet
“Filtration” (521B1009), which also will provide
you with an explanation of ltration denitions
and a guidance on how to select the right lter.
Monitoring
It is recommended to continuously monitor the
following conditions:
tlter clogging
tpressure (inlet- and outlet side of the pump)
3. Building up the
pump unit
3.1 Mounting
1. Mount the coupling ush or maximum
1 mm oset from the pump shaft end.
Ensure an air gap between coupling and
pump ange of min. 4 mm (0.16 inch).
2. Mount the bell housing on pump. Secure
nuts with the right torque.
3. Measure the longest distance “A” from top
of bell housing to the button of coupling
claw.
4. Mount the coupling on motor shaft. Ensure
the coupling and motor ange are not in
contact with each other.
5. Measure from motor ange to the top of
the coupling. That measurement “B” shall
be 3-5 mm (0.12 - 0.2 inch) shorter than the
measurement “A”.
6. Adjust respectively, verify the measure-
ment, and secure both couplings with the
right torques on the locking screws (see
coupling operation & mounting instruc-
tion).
7. Mount the elastic gear ring and mount the
bell housing/pump on the motor. After
mounting it must be possible to move the
elastic gear ring 3-5 mm (0.12 - 0.2 inch)
axial “C”. The check can be done through
the inspection hole of bell housing. Secure
ange bolts with the right torque.
