necessary that the pump is only put into operation when it is completely submerged in water, avoiding any
dry running of the pump. The engine is fitted with a special seal fitted on the shaft to protect the internal
components from pollutants or abrasive substances. Cable connections below the water level must have a
vulcanized joint to ensure tightness.
