Abstract
A full-circumferential flow pump has a circumferential fluid passage between a pump casing and a motor provided in the pump casing. The full-circumferential flow pump comprises a suction-side casing having a suction nozzle, and an outer cylinder connected to the suction-side casing and accommodating the canned motor therein. The suction-side casing and the outer cylinder have flanges, respectively extending radially outwardly from an open ends thereof. The adjacent flanges of the suction-side casing and the outer cylinder are clamped by clamping flanges to connect the suction-side casing and the outer cylinder.
Claims9
A full-circumferential flow pump having a pump casing encasing a motor driving an impeller for pumping a fluid with a circumferential passage separating said pump casing and an outer circumferential surface of said motor, said pump casing comprising:
- a nozzle provided on said pump casing, said pump casing being made of sheet metal;
- a flange detachably mounted on said nozzle and having a rigidity greater than that of said casing;
- and
- a seal surface provided on an axial end of said nozzle for mating with another flange to be coupled to said detachably mounted flange.
