Accessory part prepared
Operating conditions for the accessory part checked
Tool and material:
–
Face wrench (125/6 AF)
1. Using the face wrench, unscrew the volute casing cover
clockwise from the volute casing (5). Note this is a left-hand
thread.
2. Using the face wrench, screw the adapter (6)
¿
nger-tight
into the left-hand thread of the volute casing (5). In doing
so, ensure the following:
–
The sealing ring is positioned correctly
–
Do not install the sealing ring dry
3. Depending on the installation situation, proceed as follows:
–
When installing the suction extension (8): screw the
suction extension (8)
¿
nger-tight into the adapter (6).
Note this is a right-hand thread.
–
If necessary, screw the suction strainer (7)
¿
nger-tight

À
ange adapter
Accessory part prepared
Operating conditions for the accessory part checked
1. Unscrew the union nut (3) from the discharge
À
ange (4). If
necessary, remove the insert from the discharge
À
ange (4).
2. Position the discharge elbow /
À
ange adapter (1) on the
discharge
À
ange (4) and align it.

À
ange
adapter (1)
¿
nger-tight to the discharge
À
ange (4).

Connecting the pipes
NOTE
Material damage due to excessive forces and torques on
the pump.
Ensure pipe connection without stress.
5.5.1
Keeping the piping clean
NOTE
Material damage due to impurities in the pump!
Make sure no impurities can enter the pump.
1. Clean all piping parts and
¿
ttings prior to assembly.
2. Flush all pipes carefully with neutral medium.
3. Ensure no
À
ange seals protrude inwards.
4. Remove any blind
À
anges, plugs, protective foils and/or
protective paint from the
À
anges.
5.5.2
Installing the pressure pipe
1. Remove the transport and sealing covers from the pump.
2. Fit the pressure line stress-free and sealed
3. Ensure no seals protrude inwards.
5.5.3
Inspection for stress-free pipe connections
Piping installed and cooled down
1. Disconnect the pipe connecting
À
anges from the pump.
2. Check whether the pipes can be moved freely in all direc-
tions within the expected range of expansion:
–
Nominal width < 150 mm: by hand
–
Nominal width > 150 mm: with a small lever
3. Make sure the
À
ange surfaces are parallel.
4. Reconnect the pipe connecting
À
anges to the pump.
5. If present, check support foot for stress.
