Application case A, preassembly of the pump casing
To preassemble the pump casing
(I)
:
1. Glue the cylindrical pin
into the mechanical seal
chamber
Note: Glue the cylindrical pins into the mechanical seal
chamber so that they do not touch the shaft when the unit is
fully assembled. Ensure that the cylindrical pins are fully en-
gaged in the bores of the stationary seal ring
. If the
stationary seal ring does not feature holes, the cylindrical
pins must engage in the longitudinal recesses in the station-
ary seal ring (see "Sectional drawing of shaft seal").
and
into the mechanical seal
chamber.
3. Guide the preassembled mechanical seal chamber into the
pump casing
4. Place the thrust collar
cure with snap ring
.
Preassembly of the pump casing is now finished.
5. Equip the stationary seal ring
with an O-ring
.
6. Guide the stationary seal ring into the mechanical seal cham-
ber.
Note: Guide in so that the cylindrical pins of the mechanical
seal chamber engage in the slots on the stationary seal ring.
Preassembly of the mechanical seal chamber is now fin-
ished.
7. Mount the preassembled pump casing
on the shaft as
described in
Chapter 9.10.3, "Mounting of the Pump Casing"
.
8. Place the thrust collar
cure with snap ring
.

To complete assembly on the shaft
(II)
:
9. Equip the rotating seal ring
with an O-ring
10. Equip the seal driver
and
11. Slide the rotating seal ring with the thrust collar
,
the spring
, and the seal driver onto the shaft. Let
the folded end of the spring snap into the rotating seal ring.
12. Finish the assembly of the shaft seal by attaching the impel-
