1. 

Lightly grease o-ring (4) in the leakage drain.

2. 

Remove the two hexagon screws (A) and push the leakage 

connection (E) over the shaft pivot (B) against the shaft bearing (C).

Do not use grease containing mineral oil for EPDM seals!

3. 

With DN 25 to 65 tighten the shaft bearing (C) together with the 

leakage connection at the housing flange (D) by the hexagon 

screws (A).

4. 

With DN 80 to 125 use the hexagon screws (2) supplied with the 

leakage connection for fastening purposes.

As shown in the illustration, the leakage drain can be designed with 

weld end, optionally with round thread or other connections.
