per hour
and so that the volute and seals are always submerged

The level regulation should be intrinsic save with safety level of a least SIL1
.
Check that the motor is adequately cooled.

This installation represents a dry installation where the pump is equipped with a cooling system.
Points of attention:
The discharge- and suction flanges should be exactly in line with the piping system.
This installation may not create forces on the discharge- and suction flanges.
Check the cooling system regularly for blockages.
To do this, therefore the cooling jacket must be taken off.
The bolts ad nuts on top of the cooling jacket, or suspension bracket must be reconnected.
Prior to inspection, close the valves in discharge and suction pipelines!
