4.1
Inspection of the pump
• Construction with stuffing box packing: Remove the guards (0270). Check whether
the nuts (1810) have not been over tightened. If necessary, loosen these nuts and
tighten them again by hand. Fit the guards (0270).
• Check whether the stub shaft turns freely. Do this by turning the shaft end at the
coupling a few times by hand.
4.2
Inspection of the motor
Check whether the fuses have been mounted.
4.3
Preparing the unit for commissioning
Proceed as follows, both when the unit is put into operation for the first time and after the
pump has been overhauled:
1 Fully open the stop valve in the suction pipe. Close the delivery stop valve.
2 Fill the pump and the suction pipe with the liquid to be pumped.
3 Turn the pump shaft a few times by hand and add more liquid, if necessary.
4.4
Checking the sense of rotation
Beware of possible non-screened rotating parts, when checking the sense of
rotation!
1 The sense of rotation of the pump is indicated by an arrow. Check whether the sense
of rotation of the motor corresponds with that of the pump.
2 Let the motor run for only a short time and check the sense of rotation.
3 If the sense of rotation is
not
correct, alter the sense of rotation. See the instructions
in the user manual belonging to the electric motor.
4 Fit the guard.
4.5
Start-up
1 Open the stop valves in the supply and return lines for flushing or cooling liquid, if the
pump is connected to a flushing or cooling system.
2 Start the pump.
3 As soon as the pump is under pressure, slowly open the delivery stop valve until the
working pressure is attained.
Make sure that when a pump is running, rotating parts are always properly
screened the guard!
