7 Servicing/Maintenance
NOTE
The submersible motors, with the exception of the 14D type series, are designed
with a CrNi steel shaft end and do not need to be protected against corrosion.
The 14D submersible motor is supplied with a sealed sleeve coupling that protects
the motor shaft from contact with the fluid handled.
If a submersible motor is supplied without a pump, a sealed sleeve coupling must
be used for mounting the pump on the motor.
Make sure this protection is also maintained when the pump is dismantled or
replaced.
ü Lifting equipment of sufficient load-carrying capacity is available.
(ð Section 5.2.6, Page 30)
ü A mounting flange or mounting bracket and lifting straps are available to aid
assembly.
ü Loctite 242 has been prepared.
ü The cleaning agent (e.g. acetone made by Rhinix or similar) has been prepared.
ü Grease (approved for drinking water) is available.
ü A torque wrench is on hand.
ü Common assembly tools are on hand.
ü The general assembly drawings are on hand.
1. If already assembled, remove the suction strainer and cable guard from the
pump.
2. Clean all locating surfaces, contact surfaces and threads with a cleaning agent.
Thoroughly remove any residues of the preservative.
3. Grease the shaft stub of the motor and the sleeve coupling of the pump.
4. Apply a thin layer of grease to the locating surfaces and contact surfaces.
5. On new motors, remove the transport lock from the shaft.
Fig. 43: Transport lock
ð UMA 300 and 14D submersible motors: Remove the screw (1) and strap (2).
ð UMA 150, UMA-S 150, UMA 200, UMA-S 200, UMA 250 and UMA-S 250
submersible motors: Remove the transport support from the shaft. Pull off
the protective cap.
6. Position the motor vertically and secure it against tipping over.
7. Suspend the pump from the crane and align it so that the cable recess, coupling
sleeve and screws/bolts are in the correct position.
8. Centre the pump, fit the sleeve coupling around the shaft end, and lower the
pump.
9. Fit nuts on pump/motor assembly studs. Apply Loctite 242 and tighten the nuts
by hand.
