1401 Pump unit installation
5.6
WARNING
The designer of the installation that includes the pump unit is responsible for taking
the necessary measures to prevent an internal explosion and, in the event an
internal explosion nevertheless occurs, to stop it and limit the consequences.
5.6 Suction pipe
The suction pipe must meet the following requirements:
– Place the pump or pump unit as close as possible to the pumped liquid.
– The pipe must be as short as possible.
– Run the pipe so it slopes upwards toward the pump to prevent the formation of air pockets.
– If the pipe tapers, the pipe must slope downwards toward the pump. Place a shut-off valve between
the float chamber and MP to prevent overpressure on the MP.
