5.
Rotate the rotor slowly in a direction to feed the hose
onto the taper.
6.
Tighten all 4 bolts fully to clamp the hose and ensure
the hose can be seen through the aperture in the side
of casing formed between the flange and the casing.
7.
Run the pump forward and stop when the hose
protrudes from the other end by about 30mm
8.
Repeat the sequence for installing the flange (refer
points 1-6)
5.6.3
Fitting the port flange (Split flange assembly)
Hose in position and protruding about 30mm on the
inlet side
(the side through which the hose had been
inserted)
1.
Place both halves of the steel flange assembly around
the appropriate hose insert.
2.
Screw the halves together with the screws provided
and tighten with a screwdriver, use a smear of grease
on the screw threads to help avoid seizure.
3.
The flanges are then assembled into the hoses on the
pump as per the standard solid flange assembly.
(Refer 5.6.2)
4.
It is recommended the flange bolts be installed with a
small amount of grease smeared on the thread.

5.6.4
Filling the pump with lubricant
The safety data sheets for both Verderlube and
Verdersil are available from the manufacturer for
compatibility check
.
1.
Provide a suitable container to collect split lubricant.
2.
Ensure compatibility of lubricant with the pumped
liquid.
Fill the pump casing with lubricant to the lowest bolt hole of
the inspection window (→ 10.1.6 Lubricants).
5.7
Connecting the pipes
NOTE
Contamination of pumped media due to impurities in the
pump!
Care should be taken to avoid ingress of contaminants
into the pumped media.
1.
Clean all piping parts and fittings prior to assembly.
2.
Ensure that the flange seal do not protrude inwards
occluding the flow path.
3.
Remove flange covers on both the suction and
discharge side prior to installation.
5.7.1
Installing the piping
1.
Check all fasteners are tightened (→ 10.1.3
Tightening torques)
2.
Remove the transport and sealing covers from the
pump.
3.
Before connecting any piping to the pump: Ensure that
the hose is properly secured by running the pump dry
for 10–20 revolutions in both the directions.
4.
Run the pipes in a continuous upward or downward
slope to avoid air pockets
5.
Connect the piping
