6.7 FITTING BEARING COVER AND SHAFT SEAL COVER
Place the gasket between pump casing and shaft seal cover on the shaft seal cover where it
can be held with a little grease. Fit and fasten bearing cover and shaft seal cover. Check that
the drain passage for the shaft seal faces downwards.
S32-25-110N:
Place the gasket (21) between pump casing and bearing housing on the bearing housing.
Check that the non-return flap is placed correctly in the pump casing. Lead the bearing
housing into place and fasten. Note that the drain passage for the shaft seal faces
downwards.
S50-32-135N:
Place the gasket (21) between pump casing and bearing housing on the bearing housing.
Lead the bearing housing into place and fasten. Note that the drain passage for the shaft seal
faces downwards. If the shaft cannot rotate freely, dismantle the bearing housing again, and
place an extra gasket (21) between bearing housing and pump casing.
6.8 FITTING COUPLING
Fit sunk key . If the coupling is fitted on the assembled pump, take care that you do not
damage the bearing by pressing the coupling too hard. The coupling might be heated to
facilitate the fitting. If the coupling is fitted before assembling the pump, the shaft is supported
at the opposite shaft end while the coupling is pressed into place. When the coupling bears
against the shoulder of the pump shaft, fit the pointed screw.
6.9 SHAFT
When the pump has been assembled, check that the shaft rotates freely.
7. FROST PROTECTION
Pumps which are not in operation during frost periods are to be drained to avoid frost damage.
Remove the plug in the inlet cover to empty the pump. Alternatively, it is possible to use anti-
freeze liquids in normal constructions.
