Setup and connection
5 Setup and connection
For pumps in ex plosion-hazard areas (→ ATEX additional
instructions).
NOTE
Material damage due to distortion or passage of electrical
current in the bearing!
Do not make any structural modifi cations to the pump unit
or pump casing.
Do not carry out any welding w ork on the pump un it or
pump casing.
NOTE
Material damage caused by dirt!
Do not remove the transportation locks until imme dia te ly
before installing the pump.
Do not remove any covers or transport and sealing covers
until immediately before connecting the pipes to the pump.
5.1 Preparing the setup
5.1.1 Determining the setup type
NOTE
Damage to the bearings and shaft seal due to incorrect
setup type!
Set up t he pump accord ing to the order-based setup type.
Determine correct setup type (→ order data she et).
5.1.2 Checking the ambient conditions
Make sure the required ambient conditions are ful
filled
(→ 9.2.1 Ambient conditions, Page 47).
5.1.3 Preparing the installation site
Ensure the installation site meets
the following conditions:
– Pump is freely accessible from all
sides
–Sufficient space for the install
ation/removal of the pipes
and for maintenance and
repair work, especially for the
removal and in stallat
ion of the pump and the motor
– Pump not ex posed to e
xternal vibrations (damage to
bearings)
– Frost protection
5.1.4 Preparing the foundation and surface
Setup options:
– With concrete foundation
– With steel foundation frame
Make sure the foundation and surface m eet the fo llowing
conditions:
–Level
– Clean (no oil, dust or other impurities)
– Capable of bearing the weight of the pump unit and all
operating forces
– Ensure the pump is stable and cannot tip over
– Ensure base plate makes conta ct over entire surface
– With concrete foundation: standard concrete of
strength class B 25
5.1.5 Removing preservative
If the pump is to be put into operation immediately after
setup and connection: Remove the preservative prior to
installation (→ 4.4 Removing preservative, Page 14).
5.1.6 Installing the heat insulation (optional)
Only necessary to maintain the temperature of the pumped
liquid.
NOTE
Material damage on the bearing or shaft seal due to over-
heating!
Install heat insulation only on the pump casing.
Install the h eat insulation properly.
