Pump casing disassembly
1. Remove the hex. bolts (901.1) and drain plate (122.1) to
drain liquid out of the pump unit.
For the pump model without drain, neutralize the liquid
or flush the pump unit out. And then remove liquid by
dismantling the pump or pipework.
WARNING
If the hex. bolts are loosened at once, liquid may
fly off, resulting in personal injury.
2. Remove two mounting hex. bolts (901.7) on the foot
support.
3. Remove four pump unit mounting hex. bolts (901.5) on
the bracket (330).
4. Pull the motor backward by alternatively screwing in
the two bolts (M12×100: for back pull out). Screw in
the bolts by approximately 80 mm.
5. Pull out the motor with bracket, lifting it by the crane.
Draw the motor out straight so that the drive magnet
(858) does not come in contact with the rear casing
(158).
Keep the motor balanced when it is lifted up.
6. Unscrew the hex. bolts (901.4) which is fixing the rear
casing support to the cover (100.2) and then remove
the rear casing support.
NOTE: The rear casing and the rear casing
cover may be removed together with the
rear casing support.
Be careful not to drop the impeller (230)/
magnet capsule (859) unit from the rear
casing.
