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). |

1. A pump, comprising:
a stator; a suction conduit comprising a suction stub and a pressure stub, wherein the pressure stub is disposed downstream of the suction stub along a flow direction of the suction conduit; an impeller, rotatably disposed within the stator, wherein the impeller is configured to convey a fluid through the suction conduit from the suction stub to the pressure stub; a gap disposed between the stator and the impeller; a storage space for particles, disposed in the stator, wherein the storage space is in fluid communication with the gap; and a return line, disposed in the stator, providing fluid communication between the storage space and the suction conduit, wherein the suction conduit is downstream of the storage space along a flow direction of the return line such that, in use, the particles are conveyed from the storage space to the suction conduit through the return line. |
