3.8.3.2.
Discharge Side

Put a new O-Ring Diaphragm [23] properly greased over the hose into the groove.

Put the Medium Flange [15] on the discharge side over the hose and fix it with the nuts
tightened by hand.

Cut the diaphragm with a sharp knife so that 2 mm are remaining over the medium
flange.

Grease the hose bush discharge and put the O-Ring [52] over the hose bush. (Only
metal pumps)

Press the hose bush into the hose. Make sure that the hose does not slide into the
medium flange. Fix the hose with a screwdriver from the side if needed. Make sure that
the balance tube is inside the hose bush. When the hose bush is pushed completely in
the medium flange, Assemble (1, 24, 16,19, 20, and 11) and tighten the Screw with Nut
(38) and then the nuts on the medium flange.
3.9. Filling of Hydraulic Liquid
There are two different methods of filling the pump. This depends on the local circumstances:
3.9.1.
Pump is flooded from the suction side
When the suction side of the pump is flooded, follow the instructions here. Otherwise, when
the pump has to suck from a tank below the pump level, see chapter 3.10.2. The pump is
flooded, when the level of the slurry in the tank is over the discharge manifold of the pump. If
this is not the case, the pump can be flooded by a water connection on the suction side.

The advantage with a flooded pump is the fact, that the pressure of the slurry opens
the diaphragm in the manifold.

The pump has to be assembled complete and installed in the plant with all
connections.

The valve from the slurry tank has to be opened, so that the slurry flows into the
pump

to open the hose diaphragm.

Switch on the control power and leave the air supply open.

Close the drain nozzle on the downside of the housing.

Open the oil filling nozzle on the top of the housing

Remove one sensor cable, pump will make one stroke and stop. Fill opposite side
with hydraulic liquid.

Screw out the ventilation screw (4 mm) from the side of the lower flange on the top
of the pump.

Fill in the oil, till it comes out of the ventilation hole.

Screw in the ventilation screw.

Close the filling nozzle. Single acting pump (FP25) is now ready for operation. At the
double acting pumps remove other cable from sensor then put first cable back, pump
will make one stroke, so that the piston moves to the left side. Attention! Piston
moves only, when the valve on the discharge is opened. Now the right side can be
filled like described above.

Put all cables back and pump is ready.
