The spiral impellers are sandwiched between the top plate and the bottom plate to combine the top plate and the bottom plate together. Each spiral impeller has two wedges to complementary engage with another wedge of an adjacent spiral impeller. At least one male engaging element is formed on one wedge of each spiral impeller, and a female engaging portion is defined in the other wedge to engage with each respective male engaging element on the adjacent spiral impeller.
