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.
1. Slide the pump casing (49) and the shims (50) over the shaft
to the flange (51) and screw on.
Fig. 33 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-
ances," page 18 ).
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
attached 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
following sections with the application cases A to F. The version
for your order can deviate from this.
