Water pump with impeller
By setting radial grooves between the impeller body and the top cover, the fluid flow in the flow channel is regulated, which solves the friction problem between the impeller and the volute casing, improves the operating efficiency and life of the water pump, and reduces noise.

AI Technical Summary
In existing water pumps, friction between the impeller and the volute casing leads to wear, reduced operating efficiency, increased noise, and shortened service life. The traditional wear-resistant plates have failed to effectively solve these problems and will continue to cause further friction after wear.
Multiple grooves are provided between the impeller body and the top cover. The grooves are distributed radially to regulate the fluid flow in the flow channel, reduce instantaneous pressure fluctuations, and reduce contact friction between the impeller and the volute.
It effectively reduces the frictional resistance and noise of the impeller, improves operating efficiency and flow rate, extends service life, and reduces wear on the wear-resistant plates.
