Mounting distance (motor cooling)
The assembly procedure is standardized for various motor-pump combina‐
tions. Optional components are indicated in the assembly pictures with (x).
Use mounting screws (number, size, tightening torque) acc. to the tables
about motor-pump units to be mounted.
Assemble the components according to the drawing and observe all assem‐
bly steps. Tolerance of the specified tightening torque (M
For screw connections use screw lock, e.g. Loctite 243 when proceeding the
following working steps 1 to 4 and observe the specified tightening torques.
NOTICE
Do never beat onto the shaft end and do not exceed the allowed axial and
radial forces of the motor.
By heating the hubs (approx. 80 °C), it is easier to draw it on onto the shaft.
CAUTION
Wear protective gloves if you assemble heated coupling elements.
1. Assemble pump hub onto the pump shaft
Insert the pump hub 3.1 onto the shaft of the pump by considering the
adjustment dimensions and fasten the hub with the clamping screw
3.5b.
2. Assemble the motor hub onto the motor shaft
If provided, insert the distance sleeve 6.2 onto the shaft of the motor.
Insert the motor hub 3.3 onto the shaft of the motor by considering the
adjustment dimensions and fasten the hub with the clamping screw 3.4.
3. Screw on pump on bellhousing
Fasten the pump 1 with screws 1.1 and washers 1.2 onto the bellhous‐
ing 2. The leakage hole within the bellhousing must show down in the
case of horizontal assembly.
