Abstract
A pond pump comprising an impeller (2) which rotates about an axis of rotation (X) within a pump housing (1). The pump housing (1) comprises a suction inlet (11) that is coaxial to the impeller (2), a pressure outlet (14) for the water that is to be conducted, the pressure outlet (14) being disposed in a radial to tangential direction relative to the impeller (2), and a counterflow plate (12) between the suction inlet (11) and the pressure outlet (14). The impeller (2) is fitted with a radially disposed disk (22) with vanes (21) that are arranged on one side thereof. The counterflow plate (12) is on the impeller side encompassing the vanes (21) while channels (23) that are formed between the vanes (21) have a cross-section which tapers from the inner radial face to the outer face.
