Dismantling the pump
In most cases the entire pump is dismantled, to inspect respectively repair it in the work
shop, under clean conditions.
1 Ensure the shut-off valves are closed and the pump is drained.
2 Open the junction box and disconnect the wiring.
3 In case a foot/flange motor (IM2001 - B3/B5) is mounted: remove the fixation bolts
of the motor feet.
4 Disassemble the appropriate bolts and nuts and disconnect the discharge and
suction flanges from the piping system.
5 Remove the fixation bolts of the pump feet.
6 Remove the pump, using a hoisting device, and place it on a pallet for further internal
transport.
Place a warning sign close to the pump on the pallet, warning against the
hazards of the magnetic field!

Disassembly of the outer rotor
1 Place the pump vertically on a work bench, resting on the suction flange.
2 Disassemble bolts (0950) and nuts (0900).
3 Remove the fan protective cover of the electric motor and screw a lifting lug into the
threaded hole in the shaft end.
4 Fix a hook or a lifting belt to the lifting lug and pull off the motor and the outer rotor
from the pump casing, using a hoisting device. Initial resistance is experienced due to
the strong magnetic forces.
Be prepared for a sudden jolt of the load!
