Abstract
The centrifugal electric pump comprises a tubular- shaped external casing configuring at least one suctioning opening and one discharge opening; a pumping unit axially inserted into the casing to suction a liquid through the suctioning opening and transfer the liquid flowing out through the discharge opening; a motor unit axially inserted into the casing and suited to be op- eratively connected to the pumping unit; closure means suited to insulate an accommodation compartment of the motor unit from the liquid supplied by the pumping unit and from the liquid present outside the casing.
