6.3 Dismantling the impeller
If stubborn blockages form in the spiral housing, the spiral housing and the impeller can be dismantled via
the following steps:
Caution: Work may only be carried out on it when the pump is shut down and secured
against restarting.
1. Remove the four hexagonal screws with washers (M5) and the
suspension eyelets on the stainless steel housing between the
spiral casing and the engine.
2. Remove the stainless steel cover.
3. Loosen the suction cover and place this to the side on the
support frame, so that you can work without any hindrance
from the suction cover
4. Remove the four cylindrical screws with the hexagon socket
(M12), inside the pedestal, from the motor flange to the spiral
casing.
(The picture only shows the two bottom screws; the other two
screws are positioned above.)
5. Remove the spiral casing. With
stubborn blockages, it may be
necessary to remove the spiral
casing with the help of two
screwdrivers. To do so, place
the screwdriver on the two
designated slots on the spiral
casing and lift the spiral casing
out. To remove the supporting
frame, you have to turn the
spiral casing by 90 - 45 and
take it out.
6. Remove the countersunk screw with torx (M8) from the impel-
ler.
7. Pull the impeller out of the shaft. After the impeller is removed
from the shaft, the polygon connection has to be checked for
damage.
