This paper reviewed lots of the excellent hydraulic models of non clogging double channel impellers, gave the values of inlet speed coefficient K D1 and outlet speed coefficient K D2 , and introduced the ways of calculating radius R 1 of front cover board, radius R 2 of back cover board, and the width b 2 of impeller outlet. A mutable, isogonal logarithm spiral line is used as the midline of impeller plan channel, because it allows the inlet and outlet angles of fluid changed, and makes the design more reliable. This paper adopts isogonal logarithm spiral line to the equation of impeller plan out channel, that makes the channel gain an appropriate thickness and a good change rule of thickness. The change rule of section area is an arc. It is not only adapted to all specific speed, but also increases impeller non clogging performance. At last, an example of design and its test is given, the test shows that the method used in the paper is completely right.
