5.1 Mounting the product

SE1 and SEV pumps are designed for two installation
types:
• submerged installation:
- vertically on an auto coupling
- vertically, free-standing on a ring stand.
• dry installation:
- vertically on a base stand
- horizontally with brackets secured to a
concrete floor or foundation.
For WIO-sensor versions, the outlet pipe must be
directed upwards to ensure proper operation of the
sensor.
All Ex pumps are equipped with a WIO
sensor.
In case of dry, horizontal installation, the
outlet pipe must be directed upwards to
ensure the proper operation of the WIO
sensor.
5.1.1 Submerged installation
Pumps for permanent installation can be installed on
a stationary auto-coupling guide rail system. The
auto-coupling system facilitates maintenance and
service as the pump can easily be lifted out of the pit.
Before beginning installation procedures,
make sure that the atmosphere in the pit is
not potentially explosive.
Make sure that the pipes are installed with-
out the use of undue force. Do not allow
loads from the weight of the pipes to be
carried by the pump. Use loose flanges to
ease the installation and to avoid pipe ten-
sion at flanges and bolts.
Do not use elastic elements or bellows in
the pipes. Never use these elements to
align the pipes.
The guide rails must not have any axial
play as this would cause noise during op-
eration.
