QZ submersible axial-flow pump and QH submersible mixed-flow pump of Shanghai Liancheng (Group) Co., Ltd. are a new generation of axial-flow pumps and mixed-flow pumps based on digesting and absorbing the advanced technology of similar products at home and abroad, combined with our company's many years of design experience, which are specially designed for large flow and low lift occasions. The hydraulic models have reached the leading level in China. Compared with the old models, the flow rate is increased by 20%-30%, the efficiency is increased by 3%-5%, and the cavitation resistance is excellent. The lift of QZ submersible axial-flow pump is generally less than 10m, and that of QH submersible mixed-flow pump is generally less than 20m. This product is the best replacement of traditional axial flow pump and mixed flow pump.
