Fitting the impeller
ü
The pump has been placed in a horizontal position on a wooden support and is
protected against rolling off.
ü
The impeller-end mechanical seal 433.02 has been installed.
1. Insert and fit two keys 940.02 into the keyway.
2. Coat all sides of the shaft seat and shaft thread with an assembly paste which
prevents seizure of the chrome steel parts.
3. Guide impeller 230 onto shaft 210 until it abuts against the shaft collar.
ð
This is as far as the impeller can move along the shaft. This position results in
the maximum possible clearance between bellmouth with casing wear ring
and impeller vanes.
4. Screw impeller nut 922 onto the shaft thread.
5. Align the holes of impeller 230 and impeller nut 922 and fasten them with
hexagon socket head cap screws 914.07.
