7.3 Assembly
7.3.1 Preparations for assembly
CAUTION
Improper assembly results in aggregate damage!
►
Assemble the pump in accordance with the principal rules
of mechanical engineering.
►
Use original spare parts only.
►
For aggregate assembly, consult the corresponding cross-
sectional drawing.
►
Assemble the pump/aggregate in a clean and level assem-
bly area.
The following must be observed during assembly:
−
Replace seals.
−
Install only clean parts.
−
Install only inspected and flawless parts.
−
Make sure not to enter foreign bodies into the pump.
−
Keep the sliding surfaces of the mechanical seal free
of dirt and grease.
−
Observe the required tightening torques
(

Tightening torques, page 28).

1. Installation of mechanical seal, stationary unit
−
Moisten the auxiliary seal of the stationary unit of the
mechanical seal (047) with lubricant (alcohol, water).
−
Manually force the stationary unit into the casing (101).
−
Position the motor on the fan hood.
−
Slide the splash ring (507) onto the motor shaft.
−
Push the casing over the motor shaft, centre it on the
motor flange (IM B5) and adjust it.
2. Installation of mechanical seal, rotating unit
−
Moisten the auxiliary seal of the rotating unit of the
mechanical seal (047) with lubricant (grease containing
PTFE).
−
Push the rotating unit onto the motor shaft by a screw-
ing movement in the sense of winding of the spring.
−
Slide the washer (550.1) and the locking ring (932)
onto the motor shaft and slip it into the groove of the
motor shaft.
3. Installation of impeller
−
Insert the fitting key (940) into the motor shaft.
−
Push the impeller (230) onto the motor shaft.
4. Installing casing cover
−
Insert the O-ring (412) into the groove on the casing
cover (161).
−
Force the casing cover into the casing (101) and ad-
just.
−
