Abstract: A water pump for a spa or the like has a pump water inlet, a pump water outlet and an impeller driving water from said inlet to said outlet. The impeller provides the water axially introduced at the pump water inlet with a radial component which delivers the water to a large plenum chamber surrounding the impeller and which plenum chamber has an increasing cross sectional area as the water moves from the pump water inlet to a plenum chamber outlet thereby reducing backpressure in the water. The plenum chamber terminates with the plenum water outlet located closely to the impeller and a smooth transition area defines the area extending from the plenum chamber outlet to the pump water outlet. The water outlet preferably extends so that the water has a directional component which is generally parallel to the direction of the water entering the pump through the pump water inlet.

Abstract translation: 用于水疗中心等的水泵具有泵入口，泵出水口和从所述入口驱动水到所述出口的叶轮。 叶轮提供在泵入口处轴向引入的水，其具有径向部件，该径向部件将水输送到围绕叶轮的大的增压室，并且当水从泵入水口移动到增压室时，该增压室具有增加的横截面积 从而降低了水中的背压。 增压室终止于紧邻叶轮的集气室出水口，平滑的过渡区域限定从增压室出口延伸到泵出水口的区域。 出水口优选地延伸，使得水具有大致平行于通过泵水入口进入泵的水的方向的方向分量。
