For more information on the importance of
proper filtration, please consult our data sheet
"Filtration" (521B1009), which also will provide
you with an explanation of filtration definitions
and a guidance on how to select the right filter.

1. Mount the coupling flush or maximum
1 mm offset from the pump shaft end.
Ensure an air gap between coupling parts
of 3-5 mm (0.12-0.2 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 flange are not in
contact with each other.
5. Measure from motor flange to the top of
the coupling. That measurement "B" shall
be 3-5 mm (0.12 - 0.2 inch) shorter than the
measurement "A".
Monitoring
It is recommended to continuously monitor the
following conditions:
•
•
A: Elastic coupling
B: Bell housing
C: Motor shaft
D: Pump flange

Adjust respectively, verify the measure-
ment, and secure both couplings with the
right torques on the locking screws (see
coupling operation & mounting instruc-
tion).
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
flange bolts with the right torque.
