US 2017/0248141 A1 · CROSS-FLOW WAVE MAKING PUMP

Abstract

This invention relates to a cross-flow wave making pump comprising an impeller shell forming a water intake and a water outlet, an impeller assembly pivotally connected to two ends of the impeller shell, and a motor used for driving the impeller assembly; wherein, the impeller assembly comprises an impeller used for driving a liquid flow, a first turntable and a second turntable respectively fixed at two ends of the impeller, wherein the first turntable is provided with a shaft rotatably mounted in the impeller shell, the second turntable is provided with a cavity used for receiving a rotor shaft of the motor. The embodiments of the present invention can provide a sufficient liquid-circulation in a container, and significantly reduce the dead zone where the liquid flows extremely slowly. Other embodiments are disclosed.
