PURPOSE: A spiral pump having a multi-inlet and a single outlet is provided to decrease outlet noises and pump water with a high efficiency by sucking water by means of a strong suction force of a larger wing and operating the larger wing and a smaller wing at the same time. CONSTITUTION: A spiral pump having multi-inlets and a single-outlet includes a body(1). The body(1) includes a right camber and a left chamber installed an input port(10A) and an output port. A pump impeller(30) is made at a boundary line of an outer wall surface of a semi-conical and spiral type wing-shaped pump impeller. A motor supporting bearing(70B) is positioned at an upper part of the body(1). A boundary line of an outer wall surface is employed as an intake port of a smaller wing and a discharge port of a larger wing. The boundary line of the outer wall is employed as a fluid passage.
