The screw pump is a device with more applications in the food, pharmaceutical and other industries, and is divided into single screw pumps, double, three and five screw pumps according to the number of screws. The characteristics of the screw pump are stable flow, small pressure pulse, self -absorbing ability, low noise, high efficiency, long life, and reliable work. Transfer high viscosity medium.
