Assembling the pump
20. Remove the remaining screws in port
flange using the 13 mm combination
wrench.
21. Carefully separate house and port flange.
Ensure that the guide pin for the position-
ing of the house is not lost. For further
disassembling of flush valve, see page 14.
Important:
It is essential that the pump is serviced in
conditions of absolute cleanliness. All parts
must be absolute clean before mounting.
Note: Place the pump on a pallet or other
stable surface above the ground. Ensure that
the pump cannot roll. It must be possible to
place the pump vertically with the shaft
pointing downwards. This can be done
between two pallets or between two boards on
a pallet provided that the distance is minimum
100 mm (3,94 inch) – see photo page 4 para-
graph 7.
WARNING:
Do not use silicone when assembling the
pump.
Do not reuse disassembled O-rings as they
might be damaged. Always use new O-rings.
Do not reuse the shaft seal, due to risk of
leakage.
1. Lubrication
•
To prevent seizing-up, lubricate threads on
screws.
•
O-rings inside pump must be lubricated
only with clean filtered water.
•
O-rings for port flange, end flange and
black O-ring on flushing valve must be
lubricated.
•
It is important to lubricate ALL parts before
and during assembling with clean filtered
water. (Especially all PEEK parts)
2.
Place port flange as illustrated.
3.
Insert guide pin for positioning housing on
port flange. Ensure that two screw holes
can be reached from below.
