The utility model provides an install and to effectively reduce self priming pump from impeller mechanism of time of inhaling in pump chamber, includes the impeller, and the impeller includes back shroud, front shroud and between the two blade of certain quantity, the impeller outer lane is equipped with supplementary ring, and the annular has been seted up to supplementary ring bottom surface. The auxiliary circular ring plays a role in guiding water flow, so that the water flow can better enter the water outlet cover of the self-sucking pump. The ring groove has the functions of improving the elasticity of the auxiliary ring and reducing weight.

Preferably, a plurality of support columns are uniformly distributed on the top surface of the auxiliary circular ring in the circumferential direction. The support column offsets with the mechanism in the self priming pump, plays the spacing effect of avoiding axial displacement of support.

Preferably, the middle part of the rear cover plate is provided with an upward boss, the middle part of the front cover plate is turned upwards to form an opening ring, the side surface of the boss and the turning surface of the front cover plate and the opening ring form an arc-shaped curved surface, and the inner end of each blade is positioned on the curved surface of the boss. The shape of the mechanism accords with hydromechanics, and is beneficial to water outlet.

The beneficial effects of the utility model reside in that: the utility model discloses an impeller structure has good guide effect, thereby makes the air that is mixing in the rivers effectively discharge and improve out water efficiency, shortens the self priming pump and from inhaling the water time, improves user experience and feels, increases the satisfaction.
