The characteristics of the HLB series mixed flow pump vertical axial flow pump, the head is higher than the axial flow pump, and it can transport clean water with a temperature not exceeding 50 degrees and other fluids with similar physical and chemical properties. Small and medium-sized axial flow pumps are widely used in farmland. Drainage and irrigation, urban water supply and drainage, circulating water for thermal power stations, marine raising and lowering water levels, aquaculture, salt farm pumping pool water and other water conservancy projects. Large axial pumps are mainly used for large-area farmland irrigation and drainage, cross-basin water transfer and large-area drainage in low-lying areas and lake areas. .
