Application case C, preassembly on the shaft (I) and preassembly of the pump
casing (II)
To preassemble the pump casing
(II)
:
2. 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").
3. Install O-rings
and
rotary shaft seal
from the inside of the mechanical
seal chamber.
Note: Heed the installation direction for the rotary shaft seal.
See
Sectional Drawing
.
4. Equip the stationary seal ring
with an O-ring
.
5. Guide the stationary seal ring into the mechanical seal cham-
ber and install together in the pump casing
.
Note: The cylindrical pins on the mechanical seal chamber
must engage in the slots on the stationary seal ring.
6. Place the thrust collar
on the assembly in the pump
casing and secure with snap ring
Preassembly of the pump casing is now finished.
7. Mount the preassembled pump casing
on the shaft as
described in
Chapter 9.10.3, "Mounting of the Pump Casing"
.

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