A fire engine pump is provided to improve the pumping force and reduce the time and cost for the manufacture of the pump housing by integrally forming a spiral impeller. A fire engine pump comprises a pump(32) which pumps the water with the driving of an engine. The pump includes a cylindrical housing(33) in which a chamber(34) containing the water is formed; a rotary shaft(36) which is connected to a driving shaft of the engine within the chamber and is extended in the longitudinal direction of the housing; and an impeller(38) which is formed along the rotary shaft in a spiral shape and is formed close to the inner wall of the housing.
