General
         S(SM, SF, SY) type pump is an upgraded new energy-efficient product, and its scope of application is wider than that of SA, SH. Designed by using national standard specifications,it has high degrees of serialization,standardization and generalization. This type of pump has advanced performance, smooth operation, safety and reliability with the use of new structure and new material in design, applicable to conveying of various media.
         S-type pump is available for conveying fresh water or liquids having physicochemical properties similar to water.
         SM-type pump as a new product designed with a new wear-resistant structure and materials against the characteristics of loaded stream and similar water quality based on S-type pump is used to convey silt-bearing media.
         SF-type pump as a new product designed with corrosion resistant materials and mechanical seal structure based on S-type pump is used to convey various corrosive media and oil products.
         SL-type pump of a vertical installation type of S-type pump can save the pump house area.It is only applicable to special occasions,and the specific installation type and requirements are to be determined in consultation with the company. 
         SY-type pump is provided with a mechanical seal and additional cooling system based on S-type pump,used to convey various oil products and allows use of various materials.
          S, SM, SF, SL, SY-type pumps are widely used for water taking, pressurization,farmland irrigation and drainage of urban water supply & drainage, power station and industrial process systems, as well as various water an petrochemical projects.
          Performance range: Capacity 50—15000m3/h Head: 8.6—140m Temperature≤80℃。

Design of performance parameters according to user requirements is also allowed:
          Overflow material: S-type pump: Castiron SY, SM-type pumps: Ductile castiron, cast steel and stainless steel.
          SF-type pump：NiCr castiron,  stainless steel. Use of different materials according to user requirements is also allowed. 
          Direction of pump rotation: The pump rotates clockwise when seen from the from the motor end(optionally designed according to user requirements)
