10.5 Mounting the mechanical seal according
to the diagram below
Mounting the counter-ring
– A very high level of cleanliness is essential.
– In particular, the sliding surfaces must be clean and
completely undamaged.
– Neither of the two sliding surfaces may be lubri-
cated or wet.
1. Carefully clean and degrease the counter-ring hole,
shaft, shaft sleeve, mounting aid and counter-ring
(with spirit and clean fibre-free cloth).
2. Push the shaft sleeve with O-ring onto the shaft.
3. Wet the counter-ring collar and counter-ring seat
with water. Do not use oil.
4. Place the counter-ring flat in the centring bevel and
mount the mounting aid.
5. Mount the impeller and push the counter-ring
to the end position. Do not hammer.
6. Remove impeller and mounting aid.
7. Check the seat of the counter-ring, i.e. it should
have a good axial fit in the hole and be exactly
perpendicular to the shaft.

Mounting the mechanical seal:
8. Carefully clean and degrease the shaft seat, shaft
sleeve, counter-ring sliding surface and mecha-
nical seal (with spirit and clean fibre-free cloth).
9. Place the mechanical seal flat on the shaft
chamfer of the shaft sleeve (use only clean water
as lubricant).
10. Push the mechanical seal into the end position
with the aid of the impeller. Do not hammer.
11. Secure the impeller axially with a nut.
Note:
Mineral oils and greases must not be used since
the elastomers of the standard mechanical seal
are not oil-resistant.
