G type screw pump for high viscosity to reach 80% fluid conveying and containing hard particles suspended granular medium or containing fiber media delivery, there is a general pump can not be competent for the characteristics of. Its flow rate is proportional to the speed, widely used in food metallurgy, paper, printing and dyeing, chemical industry, chemical fertilizer and other industrial sectors of the use of. Transmission can be used for direct transmission of coupling, or the use of high-speed motor, triangle, gearbox and other devices. The G type screw pump has the advantages of less components, compact structure, small size, simple maintenance, and the rotor and the stator are easy to wear parts of the pump, and the structure is simple.
