8.1 DISASSEMBLY

DIN Standard
4844-W8
Close all valves before performing any operation.
●
Disconnect the electrical installation (this must be carried out by an authorised installer).
●
Disconnect and release all the cables in the connection box.
●
Release the intake and discharge hoses.
●
Empty the pump by removing the drain plugs and their O-rings.
To disassemble and assemble the pump, see exploded view drawing
VIEW DRAWING). To separate the motor from the body, remove the four screws, then extract the
motor unit together with the diffuser and the turbine. To disassemble the turbine, remove the
diffuser and its seal, release the cover on the fan of the motor and then use a clamp to lock it in
place through the opening, whilst at the same time turning the turbine to the left with a no. 14
wrench to release it from the shaft.
ATTENTION: The turbine's metal insert is sealed to the motor shaft with an anaerobic
adhesive to prevent it from coming loose during normal starting, stopping and operation of
the pump. Special care must therefore be taken when performing this operation.
The moving part of the mechanical seal will also be released when this operation is carried out.

8.2 ASSEMBLY

ALL PARTS TO BE COUPLED DURING ASSEMBLY MUST BE CLEAN AND IN PERFECT CONDITION.
To assemble the pump:
●
Assemble the mechanical seal. Position the moving part of the seal on the shaft of the impellor,
pressing it down until it fits into the seat. You must have lubricated the moving part of the
mechanical seal with water beforehand.
●
Assemble the turbine on the motor shaft, using an anaerobic sealant to fix the metal parts in
position and screwing it onto the shaft. This will connect the two tracks of the mechanical seal
together.
●
Position the diffuser onto the connecting body, correctly lining up the fixing points. The diffuser
can only be mounted onto the body in one position.
●
Position the O-rings on both the diffuser and the body.
●
Mount the motor assembly on the pump body using four 30mm long DIN692 M8.
To request a spare part, you will need the name of the part, the number displayed on the
exploded view drawing and the rating plate details.
