The motor drives the hydraulic unit. The electronic module takes over the control of the
motor.
The hydraulic unit is not a ready-to-install assembly due to the continuous motor shaft.
It is disassembled for most maintenance and repair work. For information on mainten-
ance and repair work, see "Maintenance" [} 197] section.
Motor impeller unit
The impeller and lantern together with the motor form the motor impeller unit (Fig. 4).
The motor impeller unit can be separated from the pump housing for the following pur-
poses:
ƒ
The motor with the electronic module must be turned to a different relative posi-
tion to the pump housing.
ƒ
Access to the impeller and mechanical seal is required.
ƒ
The motor and hydraulic unit must be separated.
The pump housing can remain in the pipe.
Observe "Permitted installation positions and change of the arrangement of compon-
ents before installation" [} 124] section and the "Maintenance" [} 197] section.
