Abstract
Motor-pump assembly intended for handling treatment, harmful and/or smelly fluids that includes a hermetically closed casing that defines a pumping chamber and a motor chamber, primary fluid inlet and outlet ports formed in said casing and that communicate with said pumping chamber, secondary fluid inlet and outlet ducts formed in said casing and that communicate with said engine chamber, a tree of elongated shape inside said casing and which extends in said chamber pumping and in said engine chamber, a sealing device around said shaft to prevent the flow of fluid between said pumping chamber and said engine chamber, a driving device inside said pumping chamber and mounted on said shaft so that I can rotate with it; a hermetic motor inside said motor chamber to produce the rotation of said shaft and an auxiliary driving device inside said motor chamber, mounted on said shaft and which can rotate with it to produce the circulation of the fluid through of said engine chamber.
