Abstract

1299846 Centrifugal pumps S A LEHTINEN 25 Nov 1970 [3 Dec 1969] 55967/70 Heading F1C [Also in Division B2] In a centrifugal pump for liquids containing solids, comprising a pump housing 1 containing an impeller 2, the latter includes cutting blades 6 which extend through inlet opening 4 to the exterior of the housing and co-operate with blade bits 7 at the periphery of the opening 4 to cut up solids present in the incoming flow. Teeth 10 and an additional cutter 8 may be provided. Moreover, the impeller may have more than two cutting blades 6. The pump may be of the double-entry type with two sets of blades 6 attached to a single impeller.
