10.1.3. Fitting impeller
1. Mount the pump shaft on the motor shaft and
check if run-out is OK within tolerance 0.07 mm.
2. For Ø215/265, mount the motor bracket and
shaft seal (10) to the electric motor with shaft.
NOTE: Push the slide ring over the shaft with the hand. If the rubber bellows is tight, use a
fitting tool and take care that the slide ring is not damaged. If the carbon ring is not fixed, it is
important to check that it is fitted correctly, i.e. the chamfered/lapped side is to face the seat.
The carbon ring can be held by a little grease.
NOTE: When using silicone grease on the shaft, the bellows will settle and seat in about 15
minutes, and until then tightness should not be expected. After start, check by viewing the leak
hole that there are no leaks.
