ABSTRACT:
The pump comprises a housing (1) in which are installed with a radial clearance an axial-flow suction wheel (5) and an axial-flow impeller wheel (6), which wheels are mounted on a common drive shaft (4) one after the other in the direction of flow. The inside diameter of the pump housing (1) in the zone of the suction wheel (5) decreases in the direction of flow. The inside diameter of the pump housing at the entry to the suction wheel (5) is calculated from the formula:
