Preparation
Clean all pump parts and check for damage and accuracy of
fit.
If necessary, rework or replace pump parts.
Assemble carefully and using little force in clean conditions.
The seals could be permanently deformed or break in part.
Replace all O-rings.
To reduce friction, wet the O-rings and the sliding faces with
water, alcohol, or silicone grease.
Clean the sealing surfaces of the mechanical seals with a de-
greaser, e.g., OKS 2610 Universal Cleaner. Do not allow the
sealing surfaces to come into contact with oil or grease and
do not touch with your fingers afterwards.
Tip: The joint retaining compound "Euro Lock A64.80," e.g., is suit-
able for gluing in bearings and bushings.
Tip: The screw retaining compound "Euro Lock A24.10," e.g., is suit-
able for gluing in set screws.
9.10.1 Clearance Setting for Flange Connection
Note: For pumps with flange connections, the clearance is set using
shims. To determine the exact number and thicknesses of shims
needed, first mount the impeller nut, the impeller, and the key as
follows and then remove again.
Procedure
1. Slide the pump casing
over the shaft
to the flange
and screw on.

Setting the clearance for the flange connection
2. Slide the seal driver onto the shaft.
3. Slide the key and the impeller onto the shaft.
4. Tighten the impeller nut.
5. Check the clearances. See
Chapter 9.9, "Checking of the Clear-
6. Remove the impeller nut, the impeller, and the key.
7. Remove the pump casing.
8. If the clearance is incorrect:
Adjust the clearance using the appropriate shims.
9.10.2 Mounting of Seals
The shaft seal built into the respective pump is given in the at-
tached documents in the
Order-Related Documents
in the form
of a
Sectional Drawing
and a
Replacement Parts List
.
The part numbers in this chapter correspond to DIN 24250.
The assembly of standard shaft seals is described in the follow-
ing sections with the application cases A to D. The version for
your order can deviate from this.
