Abstract

PURPOSE:To reduce the thrust force by forming a plurality of small holes in the peripheral direction in the intermediate part of a Wesco impeller and forming a C-shaped annular groove having a nearly same shape to that of a pump chamber on the inside wall of a pump housing in correspondence with the small hole. CONSTITUTION:A small hole 10a is formed at the part where a gap S is formed by the intermediate part of an impeller and a housing 11. C-shaped annular grooves 11a and 11b are formed in correspondence with the small hole 10a on the inside wall of housing 11. Therefore, the part where no differential pressure is generated on the both sides of the impeller 10 can be formed nearly uniformly in the peripheral direction in the intermediate part, in the pressure distribution, in all the radial directions from a pump chamber R1 to a sealed chamber R2. Therefore, the thrust force generated by the differential pressure can be reduced.
