Abstract

Viene descritto un gruppo di pompa a motore autoadescante con motore di azionamento elettrico, con una pompa azionabile dal motore, e una girante solidale in rotazione sull'albero motore, e con un eiettore posto funzionalmente a monte della girante. Un alloggiamento comune contiene il motore, la girante e l'eiettore ed è, inoltre, dotato nella sua zona superiore di manicotti di aspirazione e di mandata. Per produrre un gruppo di pompa a motore compatto e silenzioso, il motore presenta un albero verticale, che porta inferiormente la girante, e uno statore raffreddato lateralmente, a forza dalla mandata della girante. L'eiettore è disposto eretto e lateralmente allo statore. L'alloggiamento è di materiale sintetico e il manicotto di aspirazione e quello di mandata sono previsti nella zona terminale dell'alloggiamento opposta alla girante.A group of self-priming motor pump with electric drive motor, with a pump that can be driven by the motor, and an impeller rotated on the motor shaft, and with an ejector functionally located upstream of the impeller, are described. A common housing contains the motor, the impeller and the ejector and is also equipped in its upper area with suction and delivery sleeves. To produce a compact and silent motor pump unit, the motor has a vertical shaft, which carries the impeller below, and a stator cooled laterally, by force from the impeller delivery. The ejector is placed erect and laterally to the stator. The housing is made of synthetic material and the suction and delivery sleeves are provided in the terminal area of the housing opposite the impeller.
