For NSL350-525, Secure the sealing ring (27) and
Guard plate (38) with Counter sunk screw (39).
10.1.2. Fitting shaft seal
For pumps with balanced shaft seal type ELK (=”-L” included in pump code on name plate) please
read appendix A.
1. Clean the recess in the rear cover or the motor
bracket (ø215/265).
2. Remove the protective coating of the seat
without scratching the lapped surface and
lubricate the outer rubber L-ring of the seat with
a thin layer of silicone grease. Use a brush and
ensure that no silicone grease ends up at the
slide surface.
3. Press the seat into place with the fingers and
check that all parts are correctly imbedded.
NOTE: If it is necessary to use tools for assembling, then protect the sliding surface of the seat
to prevent it from being scratched or cut. Lubricate inner surface of the slide ring rubber
bellows with a thin layer of silicone grease (ensure that no silicone grease ends up at the slide
surfaces) and push it over the shaft. The use of a conical fitting bush as shown on the
assembly drawing is recommended to avoid that the rubber bellows is cut.
