Fig. 7‐20
Turn the half shells (1) such that the diagonal surfaces of the pump shaft
(2) rest on those of the coupling half shells (Refer to Fig 7‐20).
The coupling half shells must be tightened such that the gaps are the
same size (Refer to Fig. 7‐20).
Extract from manufacturer's installation and operating instructions:
The drive shaft and output shaft should be parallel* to one another. If the
axes lean towards one another, excess load is applied to the edges of the
bearings, causing premature wear.
The coupling may not be twisted axially. The intermediate disk should
move freely.
The coupling should not be disassembled. Interchanging of coupling links
and disks, damaged sealing rings, polluted bearings, etc. can cause
premature malfunctioning.
All three coupling disks must be aligned to the dimension** of the shaft
offset. If the intermediate disk is extremely off‐center - meaning that the
coupling links are no longer parallel - the coupling may be destroyed
upon startup.
* = axially aligned
** = within the permitted shaft offset
