3.2. USE FOR WHICH PUMPS ARE DESIGNED
The pumps can be used for lifting and distributing clean
water or water with a sand content not exceeding the limit
given in chap. 4.
The submersible motor-driven pumps are used:
– for industrial water supply systems;
– Pressure boosting systems;
– Medium-capacity sprinkler systems for fire fighting;
– jet or flood irrigation systems;
– for any applications involving drawing water from a well.
Use the motor-driven pumps based on their technical speci

The submersible motor-driven pumps must not be made to
work without water.

lowering to a point where the pump will be exposed, you will
need to install a minimum-level sensor as a safety measure.
