The three bladed rotor pump is suitable for transporting liquids containing solid particles. The three blade rotor pump is especially suitable for conveying media with high viscosity, concentration and particles, which are easy to form foam in the conveying process. This type of pump can maintain the original quality of the transported material without causing any physical or chemical reactions. Its conveying flow can be accurately controlled and can be used as a metering pump. The product parameters of the three bladed rotor pump include a nominal diameter of DN25-DN108mm, a flow range of 100-50000L/h, a pressure range of 0.2-1.2MPa, and a motor power of 0.25-30KW. The structural characteristics of this pump make it particularly suitable for transporting liquids containing solid particles. Even when transporting materials with high viscosity and larger particles, it has certain advantages and can effectively transport particularly viscous materials while maintaining the original quality of the materials
