4. Assembling the pump
1. Lubrication
• To prevent seizing-up, lubricate threads on
screws.
• O-rings inside pump may be lubricated only
with clean filtered water.
• O-rings for port flange, mounting flange
and black O-ring on flushing valve may be
lubricated with a small amount of grease.
• It is important to lubricate ALL parts to
be assembled with clean filtered water
(Especially all PEEK parts).
3. Insert guide pin for positioning housing on
port flange.
Ensure that two screw holes can be reached
from below.
5. Position housing aligning 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.
4. Mount O-ring.
2. Place port flange with O-ring pointing upwards.
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 50 mm.
WARNING:
Do not use silicone when assembling the
pump. Do not reuse dismantled O-rings;
they might be damaged. Always use new
O-rings.
