Installation of the mechanical seal, single-
acting with throttle ring
!
Press the throttle ring (234) with the O-ring (235)
concentrically into the mechanical seal cover
(215).
Note:
Observe even pressure distribution.
!
Drive in the locking pin (236) with a spike into the
mechanical seal cover (215). The locking pin may
not protrude on the inside.
!
Slide the mechanical seal cover (215) across the
drive shaft (118).
!
The subsequent installation of the mechanical
seal takes place as described in Chapter “Installa-
tion of the single-acting mechanical seal”.
!
Pull the O-ring (218) onto the mechanical seal
housing (214).
!
Slide the mechanical seal housing (214) with the
mechanical seal counter-ring (219) across the
drive shaft (118) and attach with the hexagon
screws (245) on the mechanical seal cover (215).
•
Installing the double-acting mechanical seal
!
Drive the locking pin (236) into the mechanical
seal cover (215).
!
Press the mechanical seal counter-ring (219) with
the O-ring concentrically into the mechanical seal
cover (215).
Note:
Observe even pressure distribution and the
locking pin. The locking pin may not protrude on
the inside.
!
Slide the mechanical seal cover (215) across the
drive shaft (118).
!
The subsequent installation of the mechanical
seal takes place as described in the Chapter “In-
stallation of the single-acting mechanical seal”.
!
Pull the O-ring (218) onto the mechanical seal
housing (214).
!
Slide the mechanical seal housing (214) with the
mechanical seal counter-ring (219) across the
drive shaft (118) and attach with the hexagon
screws (245) on the mechanical seal cover (215).
7.2.2.3 Installing the drive shaft with shaft seal
!
Slide the thrower (114) onto the drive shaft (118).
!
Press the drive shaft (118) with the mounted stuff-
ing box casing (204) or mechanical seal housing
(214) and installed stuffing box packing (207) re-
spectively mechanical seal (219) through the
bearings (104) and (103) into the bearing bracket
(110).
Note:
Observe the installation position of the
spacer ring (113) and the spacer sleeve (102).
When pressing in the
inner bearing ring
of the
groove ball bearing (193), support this with a suit-
able tool respectively press against.
Note:
With the pump sizes AE1N 380, AE2N 380,
AE4N 380, AE1E 750, AE2E 750, AED2N 560,
AED1E 1200, AE.H 200 and with all larger
pumps, the drive shaft (118) can also be pulled
through the bearings (104) and (103) into the
bearing bracket (110) with a suitable assembly
tool consisting of a guide sleeve, drawing-in
sleeve and thread bar with washer and nut. You
can purchase the assembly tool from us.
Figure 9: Drawing in the drive shaft
!
Turn the self-locking bearing nut (116) with a hook
spanner onto the drive shaft (118) and tighten.
Once the bearing nut is place without fitting toler-
ance, tighten it with about 1/16 of a turn.
Note:
In order to ensure the self-locking of the
bearing nut, replace this after loosening and tight-
ening it approx. 5 times.
!
With pumps with horizontal alignment, turn the
bearing cover (131) with the seal (132) prior to in-
stallation in such a way that the grease emer-
gence boring in the bearing bracket is closed
(110).
With pumps with vertical alignment and bearing to
the top, turn the bearing cover (131) with the seal
(132) prior to installation in such a way that the
grease emergence boring in the bearing bracket
(110) is aligned with the spare in the bearing
cover (131) and the seal (132).
!
Attach the bearing cover (131) with the seal (132)
with the hexagon screws (139) on the bearing
bracket (110).
!
Insert the feather key (101) in the drive shaft (118)
and secure it at the end with two puncher blows.
7.2.2.4 Installing the rotor and the rotor-side joint
!
Drive the sleeve for the joint bolt (303) halfway
into the rotor (401) with the brass spike.
!
Press the joint bush (302) into the joint shaft (307)
in such a way that the longitudinal axis of the oval
boring (marked by 2 notches) aligns with the
longitudinal axis of the joint shaft and that the joint
collar protrudes evenly on both sides of the joint
shaft (see figure 10). Joint bush (302) not avail-
able with:
