(54)	Modular centrifugal pump casing

(57) The invention is a new modular centrifugal pump comprising a disc (P) that joins the various parts and connects them with the motor part, to which a single scroll (V) containing the impeller (G) is applied, and a further external shell (C) having different shapes and characteristics according to the different uses for which the pump is destined. The connection disc (P), the impeller (G) and the scroll (V) constitute the common hydraulic part for the various types of pumps. The various external shells (C), suitable for being coupled with the scroll (V) and/or the connection disc (P), have different shapes and/or unions (Ca, Cm) according to the final use for which the pump is destined.
