3.2.3 Positioning the pump
The pump can be used in vertical or horizontal
position. See fig. 3.
During continuous operation, the motor and the
pump inlet must always be completely covered by
the pumped liquid.
During intermittent operation, the motor must always
be half submerged into the pumped liquid.
Fig. 3
Position of the pump
When the pipe or hose has been connected, place
the pump in its operating position.
Position the pump so that the pump inlet will not be
blocked or partly blocked by sludge, mud or similar
materials.
In the case of permanent installation, the pit must be
cleared of sludge, pebbles, etc. before the pump is
installed.
3.2.4 Pipe connection
For permanent installation, we recommend that you
·
fit a union, a non-return valve and an isolating valve
in the outlet pipe.
3.2.5 Installation on auto coupling
See figs A and B in Appendix.
Pumps for permanent installation can be installed on
a stationary auto coupling and operated completely
or partially submerged in the pumped liquid.
1. Drill mounting holes for guide rail bracket on the
inside of the pit and fasten the guide rail bracket
provisionally with two screws.
2. Place the auto coupling base unit on the bottom
of the pit. Use a plumb line to establish the
correct positioning. Fasten with heavy-duty
expansion bolts. If the bottom of the pit is
uneven, the auto-coupling base unit must be
supported so that it is level when being fastened.
3. Assemble the outlet line in accordance with the
generally accepted procedures and without
exposing the line to distortion or tension.
