4 Impeller clearance check
4.1 Dismantling base plate and strainer
Loosen the bottom nuts that secures the base plate
and remove the base plate and the strainer. (Figure
8)
Hint! Use an extension socket M16 (J 405), M20
(J 604) to dismantle base plate.
4.2 Clearance measure
Check the impeller for damage and that the impeller
runs free of the wear ring with a clearance of 0.1-
0.3mm (0.004”-0.012”). If not, adjust it or if the wear
is too high go on with “change of impeller”. (Figure 9)
Note!
A drop in capacity due to wear is compensated in a
few minutes. Just remove base plate and tighten nuts
below the wear ring to reestablish a clearance be-
tween impeller and wear ring of 0.1-0.3 mm (0.004”-
0.012”).
