How to dismantle an MB centrifugal pump – LIP SEAL

19 September 2019

How is a Debem MB- TL centrifugal pump dismantled properly?

In a few easy steps, damaged or worn parts can be checked and, if necessary, replaced, or preventative measures taken.

Only after ensuring that the pump has been cleaned internally and there are no dangerous substances, proceed as follows. Debem Srl takes no responsibility for damage to property or injury to people, arising from the implementation of the following instructions in the absence of the obligatory environmental and operator safety requirements.

1) disconnect the electrical wires entering the electric motor cover

2) disconnect the circuit pump

3) remove the screws (1)

4) uncouple the pump unit (3) and o-ring (7)

5) unscrew the caps (2), making sure you secure the impeller using a soft belt, so as not to damage the paddles

6) extract the impeller (5) from the shaft (14), taking care with the seal o-ring (4 and 6)

7) Extract the ceramic cylinder (10) together with the spacer washer (11)

8a) In the case of MB 80/100 – TL pumps, uncouple the seal support flange (8) from the remaining elements

8b) In the case of MB 110/180 – TL pumps, uncouple the seal support flange (16) from the rear flange (18), removing the securing screws (15); the seal o-ring should also be removed together with this (17)

NB: only extract the lip seal (9) from its seat if it is damaged

9) remove the screw (12) securing the lantern to the electric motor

10) extract the lantern (13)

1) slacken the dowel (not visible in the image) used to secure the pump shaft to the electric motor shaft and proceed with extraction.
