Venturi Powder Pump and Coating Installation Comprising Such a Powder Pump

A Venturi powder pump comprising a pump body, a drive gas injector and an ejector for a mixture comprising a powdered product, wherein:

• the injector and the ejector are mounted in the pump body when the powder pump is in the assembled configuration;
• the pump body defines a duct for circulating a mixture comprising the powder product, upstream of the ejector;
• the ejector is straight and extends along an ejector axis;
• the injector and the ejector are mounted directly on each other;
• the injector is straight and extends along an injector axis;
• the injector axis and the ejector axis coincide when the powder pump is in the assembled configuration;
• and
• the powder pump comprises means for indexing the position of the ejector within the pump body, in rotation about the ejector axis, which make it possible to align an inlet of a suction chamber with the mixture circulation duct defined by the pump body.
