部分をねじ状に延ばしたことを特徴とする一枚羽
根形羽根車ポンプ。 The pump casing has a conical inner circumferential surface that is formed to widen from the suction port toward the discharge casing, and the rotating surface formed by the outer edge of the single blade is conical so that the rotating surface formed by the outer edge of the single blade is close to the conical inner circumferential surface of the pump casing. In a single-blade impeller pump comprising an impeller having conical threaded blades formed on a conical hub, the axis of the conical hub or at least the apex of the conical hub is arranged eccentrically with respect to the rotational axis of the pump. A single-blade impeller pump is characterized in that the inlet portion of the blade starting from the eccentric apex is extended into a screw shape.
