To reduce assembling man-hours of a pump and a cost of the pump by decreasing the number of components.
In the pump 30 in which a casing of a pump section 15 and a motor section 20 for rotating the pump section 15 are united with each other, the casing and a load side bracket 2a of the motor section 20 are integrally formed and a counter-load side bracket 23 of the motor section 20 is fixed to the load side bracket 2a of the casing. The casing is formed of a first casing 1 and a second casing 2, wherein the first casing 1 has a water inlet opening 11, a discharge opening 12, a water inlet path 16 and a water supply path 17, the second casing 2 has a swirl chamber 10 which receives an impeller 7 mounted to a rotary shaft 26 of the motor section 20 through a partition plate 3 dividing between the swirl chamber and the first casing 1 and in the second casing 2 the load side bracket 2a is projected from an opposite side of the partition plate 3.
