FIELD: engines and pumps.
SUBSTANCE: invention relates to the centrifugal pump for supply of gas-containing suspension, in particular fibrous material suspension, which comprises the pump impeller (12), at least, with one hole (15) in the bearing plate and ribs (16) on the back side. The separator device (17) which comprises the separator housing (25) with the fixed disk (18) and the disk (22) rotating together with the pump shaft (21) is provisioned. The separator device (17) in the pump housing is located from the back side of the impeller (12) closely to it from the impeller (12) side in the axial direction. The separator (25) housing comprises the gas collector chamber (31) with the exhaust pipeline (28). The disk (22) rotating together with the pump shaft (21) has a continuous surface (23) without holes.
EFFECT: losses of material can be reduced and increase of stability of operation of the centrifugal pump at supply of gas-containing suspension, in particular fibrous material suspension is achieved.
