A spiral fluted wheel has a top plate, a bottom plate and multiple spiral impellers. 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. Accordingly, the spiral fluted wheel can be combined rapidly and precisely.

DETAILED DESCRIPTION The main objective of the invention is to provide a spiral fluted wheel for a pump that can be combined rapidly and precisely.
The spiral fluted wheel has a top plate, a bottom plate and multiple spiral impellers.
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 complementarily 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.
With the arrangements of the male engaging elements and the female engaging portions, the spiral fluted wheel can be combined rapidly and precisely.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
