7.8.5 Final assembly
♦ Deposit the housing
100
on a workbench, for ex-
ample, with the suction nozzle facing downwards.
Protect the plastic working strip against damage
with a suitable support.
♦ Insert housing gasket
401
into the centering of the
housing
100
.
♦ Mount pre-assembled slide-in unit concentrically
onto the shaft spider
338
.
♦ Press outer wear ring
502/1
into the housing
100
.
♦ Insert pre-assembled can unit. The lip of the can
insert
158
must rest on the housing gasket
401
.
Press shaft 222 carefully through the
bearing bushes 545 into the shaft spider
338. (risk of the silicon carbide breaking)
♦ Mount bracket
344
and tighten hex. screws
901/3
to the required torque, see Section 1.1 .
♦ Check whether the rotating unit has the necessary
axial play. For this purpose reach through the suc-
tion nozzle and move the rotating unit axially. The
axial play can be determined through the dis-
charge nozzle. See Section 7.7.1 .
♦ If the minimum axial play is not achieved, insert
another housing gasket 401 .
♦ Insert the pre-assembled drive unit into the center-
ing of the lantern
344
.
When inserting the unit, high axial
magnetic forces occur which decrease
abruptly after reaching maximum (up to
max. 400 N without weight).
Only hold the bearing pedestal in front
of the flange (on motor side).
(Risk of injury from being squeezed)
♦ Alternatively, the unit can be mounted using a
crane. A thread is to be provided in the drive shaft
to accommodate a crane plug for this purpose.
♦ Tighten screws
901/5
.
Tightening torque group 1.1 + 1.2 = 40 Nm
Tightening torque group 1.3 = 55 Nm
♦ Check whether the drive shaft can be easily
turned.
♦ Screw the threads for the jacking screw in the lan-
tern with the plug.
♦ Attach support bracket
183,
align and tighten.
7.8.6 Fill bearing pedestal with oil
Oil quantities:
For group 1.1 appr. 400 ml
For group 1.2 appr. 600 ml
For group 1.3 appr. 1000 ml
Groups see Section 1 .
Type of oil:
See Section 7.2.2 .
Procedure for filling with oil:
♦ Tilt constant level oiler
638/1
.
♦ Fill the oiler with oil.
♦ Swing the constant level oiler into the vertical
position.
♦ If the oil level still falls too much, pour more oil
into the oiler.

7.9 Tests
On request , the pumps are tested with water at the
manufacturer's.
The operating data measured are then documented
in a works test certificate.
If, during a test after repairs, discrepancies com-
pared with the works certificate are discovered, the
following people can be called in:
1. in-house pump office
2. The manufacturer Richter
or its local agent
The following conveying data can be checked using
the pump performance curves :
♦ Flow rate
♦ Head
♦ Power requirement
♦ NPSHR
