SEQUENTIAL FLOW TYPE CENTRIFUGAL PUMP

摘要

PROBLEM TO BE SOLVED: To provide a low flow rate high lift type centrifugal pump.SOLUTION: A sequential flow type centrifugal pump is provided in which an inner circumferential portion of a housing 3 includes a plurality of flow-in flow passages 6 and an outer circumferential portion of the housing 3 includes flow-out flow passages 7 of the same number of the flow-in flow passages. The pump includes: one impeller 4 having a part that applies a centrifugal force to liquid and that is rotated between the flow-in flow passage 6 and the flow-out flow passage 7; and a passage 8 through which liquid flowed in from the flow-in passages 6 and driven out to the flow-out flow passages 7 flows into another flow-in flow passage.
