Assembling the pump
6 | 180R9121 | 521B1018 | DKCFN.PI.013.A6.02
WARNING:
Do not use silicone when assembling the
pump. Do not reuse disassembled O-rings;
they might be damaged. Always use new
O-rings.
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 50 mm.
1. Lubrication:
• To prevent seizing-up, lubricate all
threads with PTFE lubrication type.
• O-rings inside pump may be lubricated
only with clean filtered water.
• O-rings for port flange, mounting flange
and flushing valve must be lubricated.
• It is important to lubricate ALL parts to
be assembled with clean filtered water
(Especially all PEEK parts).
3. Mount O-ring.
4. Insert pin for positioning housing
on port flange.
Ensure that two screw holes can be
reached from below.
Important:
It is essential that the pump is serviced in
conditions of absolute cleanliness. All parts
must be absolute clean before mounting.
2. Place port flange with O-ring pointing
upwards.
5. Position housing alingning pin hole
over guide pin.
6. Gently press downwards. Be careful not to
squeeze O-ring. If O-ring is damaged, the
pump will leak.
7. Screw in at least two screws.
