3.5.3 Fitting the Motor
At the pump’s flange the respective studs have been preassembled, the
washers and nuts which must be used have been enclosed with the pump.
Check to ensure that the touch protection (Fig. 3.6) has been correctly fitted
in the pump’s flange.
Insert the coupling star into the coupling half on the side of the pump.
Align the coupling halves and push the motor on making sure that the flange
surfaces run in parallel.
Any tilt between motor axis and impeller axis can give rise to increased wear
on the coupling star.
Fit washers and nuts, and tighten according to the torque levels given in Fig.
3.9.
3.5.4 Electrical Connection
Connect the motor according to Section 3.3 and to the information of the
manufacturer of the motor.
