.

For tightening torques, see table below:

11. Screw the sealing water tube 

(701.60)

 into the mechanical 

seal chamber and seal it.

12. Mount the pump casing on the shafts and slide it onto the 

gearbox.

CAUTION

The pump casing does not lie flat on the gearbox. Material 
damage from warpage of pump casing.

►

Screw the pump casing to the gearbox. The fixture depends 
on the pump size:

– Pump size 25-580: Socket screws in pump casing

For tightening torques, see table below:

13. Subsequently mount the shaft seal of the rotor; for details, 

see 

Chapter 10.9.2, "Mounting of the Rotors," page 24

.
