The utility model discloses an impeller, high wear and easy to be jammed and the manufacturing cost of the existing impeller in the utility model, a front cover, back cover plate of the blade is made of stainless steel material and a plurality of blades radially distributed between the front cover and the rear cover and the three through hole before welding, the edge of the cover plate with plastic ring, plastic ring is larger than the center hole of the inner diameter of the guide vane wheel cover, made of plastic and assembled in the rear, front wheel extends to the plastic mouth band and plastic ring keep between the radial clearance is formed along the pump impeller entrance, structure the hole axis made of hub. The front end of the pump assembly when the plastic ring contact guide vane and impeller hub cover by the floating on the pump shaft to automatically adjust the axial gap size, which can solve the problems caused by sediment abrasion and impeller stuck to a certain extent; the impeller assembly structure reduces the processing difficulty and cost.
