6 Commissioning/Shutdown
6.1 Initial commissioning
Normally, the pumps have already been test-run with water. Unless special agreements have been
made, there could still be residual amounts of water in the pump. This must be noted in view of a possi-
ble reaction with the medium.
The rolling bearings are greased for life. Regreasing is not possible and not necessary.

6.1.1 Filling the pump housing
Check to see whether the screws on the suction flange, discharge flange, housing flange and drain
flange are tightened. When retightening the housing screws, make sure that the support bracket is un-
done. Otherwise, the pump could be deformed. For screw tightening torques see
.
1.
Open the suction line fully so that the medium can flow into the pump.
2.
Open the discharge valve so that the air in the pump can escape.
If air cannot be vented into the discharge line, e.g. a drop in pressure in this line is not permitted,
venting must be performed upstream of the discharge valve.
3.
Monitor the venting operation until no air but only liquid emerges.
4.
Turn the pump shaft at the coupling several times.
5.
Monitor the venting operation again until no more air emerges.
6.
Close the discharge valve again until only the minimum flow rate is obtained after the motor has
been started.
6.1.2 Start-up
1.
Check to see whether the pump shaft can be readily turned by hand.
2.
Check the direction of rotation of the motor with the coupling disengaged.
3.
Engage coupling, check alignment and secure.
4.
Mount coupling guard.
As viewed from the motor, the direction of rotation of the pump is clockwise. See also the direction
of rotation arrow of the pump.
CAUTION:
The pump must not run dry during the check of the direction of rotation.
NOTICE:
The pump must be completely filled with liquid. The maximum admissible flow rate must not
be exceeded. Otherwise the plain bearings can run dry in both cases.
5.
Switch the motor on.
6.
Set the desired flow by opening the discharge valve.
