Double-suction pump horizontal split centrifugal clear water pump, S-type double-suction pump is suitable for industrial and urban water supply and drainage pumps, can be used as a drainage or water supply pump for factories, cities, power stations, water conservancy projects, etc., and can also be used for farmland irrigation. The "S" series pump is a high-efficiency and energy-saving product, with the characteristics of simple structure and excellent performance. For the transportation of clean water without solid particles or other liquids similar to water in physical and chemical properties, the temperature of the medium to be conveyed is 0 °C ~ 80 °C, and the allowable inlet pressure is 0.6MPa As an important form of centrifugal pump, double-suction pump has been widely used in engineering because of its high head and large flow rate. This pump-type impeller is actually a combination of two back-to-back impellers, and the water flowing from the impeller flows into a volute. Tianhong brand double suction pump has the following characteristics: it is equivalent to two single suction impellers of the same diameter working at the same time, the flow rate can be doubled under the same impeller outer diameter; the pump casing is horizontally opened, easy to inspect and maintain at the same time, the inlet and outlet of Tianhong brand double suction pump are in the same direction and perpendicular to the pump shaft, which is conducive to the layout and installation of the pump and the inlet and outlet pipes; the impeller structure of the double suction pump is symmetrical, there is no axial force, and the operation is relatively stable. In China, the irrigation pumping stations along the Yellow River have a large flow rate and a high head, and most of them use Tianhong double-suction centrifugal pumps. The Huinanzhuang Pumping Station on the middle line of the South-to-North Water Diversion Project also uses double suction pumps for water supply
