Abstract

A centrifugal pump (1) having a pumping assembly (2) provided internally with a rotary supporting shaft (4) and with at least one centrifugal impeller (3) fitted to the supporting shaft (4); the centrifugal impeller (3) having a central hub (16), front (18) and rear plates (17) rigidly to the central hub (16) coaxial with the longitudinal axis (B) of the hub, and a number of angularly spaced radial blades (19) which extend from one plate (17, 18) to the other, and project from the periphery of the gap towards the central hub (16) along a predetermined trajectory; the outside diameter (d1) of the front plate (18) being greater than the outside diameter (d2) of the rear plate (17), and the diameter (d3) of the cylindrical surface enclosing the radial blades (19) being less than or equal to the outside diameter (d1) of the front plate (18).
