QG series cutting sewage pump is made of alloy 20 chromium-molybdenum steel, which is combined with the main impeller and the cutterhead, ensuring the hardness of the cutting knife and strengthening the cutting ability. The sewage passage ability is particularly strong, and it can shred and discharge impurities such as long fibres, plastics, paper, tapes, cloth strips, straw, and ropes in the sewage. It is an updated product that cannot be compared with the traditional cutting sewage pump on the market.
