Drainage pump
1 Impeller
2 Rotor
3 Stator
4 Pump housing
5 0-ring
The rotor consists of a permanent magnet which can rotate clockwise or anti clock-wise. The rotor can
rotate one quarter revolution without movement ofthe impeller.
Ifthe impeller seizes, the rotor can therefore make small movements in both directions until the impeller
is freed. An unusual sound may be heard at Start which is quite normal.
Function check
1 Check that the impeller can move freely.
2 Check the resistance of the Stator winding. This should be 170 Ohm.
Max. capacity = 20 l/mm.
Power consumptlon = 30 W
