The single screw pump design is a revolutionary advancement in pumping technology, offering a unique solution for various fluids' transfer in numerous industries. Recognized for its ability to handle different fluids, including those that are viscous, shear-sensitive, or contain solids, this type of pump ensures a smooth and continuous flow. Its compact design and efficient operation make it a popular choice in sectors such as chemical processing, food and beverage, and oil and gas.
Single screw pumps can be used in all industries to convey a variety of media or perform high-precision metering. From low-viscosity media to non-flowing media, with or without solids, shear-sensitive, viscous, or abrasive - direct coupling can be used to achieve smooth and low-pulsation conveying of the media.



The G single screw pump consists of suction, discharge, working parts (Rotor and Stator), driving part, universal joint part seal assembly, and bearing seat. The working part is composed of a rotating eccentric rotor and stator. The rotor and stator have two contact points in every transverse section. These contact points form two sealing lines along the working parts of the rotor (or stator).
Thus comes into one or a few sealing chambers when the rotor rotates. The media entering the sealing chamber move smoothly from the suction end to the discharge end along the sealing chamber. During the whole running, the pressure pulsation is very low which has no effect upon the intrinsic construction of pumped media.
