Abstract
"PERFECTED PUMP" which is characterized by being constituted by a pump body in the form of a ring, from which the drive duct protrudes tangentially, whose ring is fixed to an upper cover provided with a central hole for passage of the impeller shaft and inlet of liquid aspirated, and has a lower cover, fixed by screws to the upper one; the impeller, housed inside the box thus formed, has its through shaft through the hole in the top cover and is coupled by plug to the shaft end of a vertical electric motor fixed to supports attached to the top cover, so that the axis of the impeller constitutes, without supports, the prolongation of the axis of the motor, placing the pump with its vertical axis submerged in the liquid to be pumped.
