The invention relates to a biogas liquid non clogging pump group pumping motor, solves the clogging, high cost and low efficiency of gas production problems of the existing charging equipment. The pump body is provided with a circular ring outer ring cutting knife, cutting outside the first impeller wear knife, the first impeller comprises a first steel sleeve, the first steel sleeve is uniformly fixed with a helical blade, spiral blade and the axis of the first set of vertical steel ring, outer cutter on the upper surface of a spiral groove, and the rotating shaft there are second impeller, impeller second including second steel, second steel sleeves are evenly fixed with discharging blades in close contact on the surface of the lower end of the outer ring and the blade material cutting knife, the upper end of the discharge blade is provided with a fixed plate, annular outer cutting knife is provided with a clamping surface of the central groove. The structure of the invention is reasonable and reliable, the flow is more fluent, the gas production period is shortened through two cutting, the gas production efficiency is improved, and the utility model has the advantages of simple structure, convenient operation and low cost.
