(54) Fluid circulation pump adapted for a household appliance


(57) The present invention is related to a circulation pump for a household appliance, comprising a motor body (1), a motor, a hydraulic body (3) attached to the motor body (1) and comprising an inlet (30) and an outlet (31), and closure means attached to the hydraulic body (3), a hydraulic chamber (6) where the fluid flows, which is delimited between the hydraulic body (3) and the closure means. The pump (100) comprises an impeller (4) housed in the hydraulic body (3) and rotating, causing a substantially circular flow of the fluid in the hydraulic chamber 6, and a stationary element adapted for aiding in discharging the fluid from the pump (100). The stationary element is attached to at least one of the elements delimiting the hydraulic chamber (6) and is arranged in the hydraulic chamber (6) such that it blocks or resists against the flow of the fluid.
