2.5.7 Coupling
If one coupling half engages with the other, the claw section is normally to be mounted on the
pump shaft and the coupling half with the smooth end face on the motor shaft. Observe the oper-
ating manual of the coupling manufacturer.
WARNING!
A coupling with a valid ATEX certificate is to be used if deployed in zone 1 and 2.
Regulations exist, e.g. for the following details:
–
Arrangement of the coupling halves
–
Max. bore diameter
–
Max. transmitted power
–
Spacing of the coupling halves
–
Maximum values for offset and angular misalignment.
Should the pump housing and motor remain on the base plate for repair work, a spacer type cou-
pling is required.
2.5.8 Final check
Check alignment of the coupling according to
Chapter 2.5.3 “Alignment of pump - coupling -
motor standard version” on page 18
again. It must be possible to easily turn the unit at the coupling
by hand.
2.5.9 Coupling guard
The pump may only be operated with a coupling guard (certified component according
to UVV) in accordance with the accident prevention regulations.
WARNING!
It must be ensured that the coupling guard used is either made of spark-free material
or the impact test required by the EN 13463 is satisfied without any reservations.
Richter offers both versions.
HINWEIS!
The operator must ensure that, after the coupling protection has been mounted, the
requirements of the machine guideline are fulfilled.
