4” ELECTRIC PUMP
Consisting of a vertical multistage pump and an immersion squirrel-cage motor, connected directly to the
pump and located underneath it. The pump and motor are equipped with shafts that run on plain bearings.
The well water is used to lubricate the pump bearings and to cool the motor. Therefore, it is absolutely
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.
USE

and distribution in civil and commercial water systems. Supply of autoclaves and tanks, washing systems,
hobby use and irrigation systems, gardening.
ELECTRONIC EQUIPMENT
All single-phase electric pumps must be connected to the electrical control panel which includes a thermal
overload protection with manual reset and capacitor (the electrical control panel can be ordered separately
or is supplied as standard with the pump in the kit versions).
For the three-phase versions, the protection is to be provided by the user.
HYDRAULIC EQUIPMENT
The electric pumps are equipped with a check valve located in the upper support. On all submersible electric
pumps it is recommended to install an additional check valve on the delivery line.
