Assembly and adjusting the diffuser and impellers (two
impellers).
Please note that the second impeller, 353477, is adjusted by washer
03176 and locked by a distance sleeve, having the same length as the
hub of the first impeller, 03016.
The guide vane, 03174, is screwed together with the diffuser, 03210,
by three screws, 03189, + Loctite in the treads. Nuts, 03031, are placed
between the diffusor and the guide vane. Partly mounted details are
put down on the stud bolts, 03249. Then put six pcs of washer 03121
and six pcs of nuts, 03031, on the guide vane.
Adjust the diffuser, 03210, against the impeller. After this the nuts are
slacked loosen (opened) a quater of one turn. It is important that the
impeller is close to the diffuser in order for the pump to give the pro-
mised high head.
That the diffuser is correct installed (parallell) can be checked by
measuring the distance from the guide vane up to the motor. The
distance between the upper side of the impeller and the guide vane is
adjusted by shims, 00179, to about 1 to 1,5 mm. Please note that the
shaft key, 03149, should be fitted after the shims.
The washers, 03121(six pcs), are placed on the stud bolts and
thereafter the diffuser, 03172. The distance between the impeller and
the diffuser are adjusted by one or several adjusting shims, 03235. It
has to be the same amount on each stud bolt. The distance should be
about 0,1 to 0,2 mm. Two nuts on eachother are then locking it all.
After this there are only the rubber sleeves, 03179, on the nuts, the
outer casing and the bottomplate left to mount and the pump is ready
to use again.
It is advisable, to save time, that the pump is always started for a
few seconds to check that the impellers are rotating while still in the
workshop. If the nuts are screwed on too tight the impellers are too
close tho the diffusers.
