A centrifugal pump (1, 110) includes an apparatus for the removal of particles, wherein the centrifugal pump includes an impeller (6, 106). A fluid (2, 102) can be conveyed by means of the impeller (6, 106) through a suction passage (5, 105) from a suction stub (3, 103) to a pressure stub (4, 104). The impeller (6, 106) is rotatable in a stator (7, 107). A gap (9, 19, 109) is arranged between the stator (7, 107) and the impeller (6, 106), wherein the gap (9, 19, 109) opens into a storage space (11, 21, 111) for particles. The storage space (11, 21, 111) communicates with the suction passage (5, 105) via a return line (12, 112) running through the stator (7, 107).
