Abstract

A centrifugal pump comprises a pump body or casing (2), a rotor (5) connected to a shaft (4), an upper removable cover (3), with the seal between the pump body (2) and the rotor (5) being ensured by rings (10, 11), attached to the casing (2), facing rings (25), attached to the rotor (5), which are made to rotate with it. According to the invention, both the fixed sealing rings (10, 11) and the bearings for supporting the rotating part of the pump (8, 9; 8bis, 9bis) are assembled on two removable side covers (6, 7) arranged at the two sides of the pump body (2).
