Single-screw pump The rotor-type volumetric pump that transports liquids by creating volume changes in the suction and discharge chambers through the intermeshing of the screw and the liner. G-type single-screw pump is an internal meshing rotary positive displacement pump that relies on the interlocking of an eccentric screw (rotor) and a fixed liner (stator) to create volumetric changes in the suction and discharge chambers for liquid transportation. This pump features a compact structure, minimal parts, and easy maintenance, enabling it to transport high-viscosity fluids as well as media containing solid particles or fibers. It boasts stable flow rates, consistent pressure, and strong self-priming capabilities, with flow directly proportional to rotational speed for convenient adjustment. It can operate at temperatures up to 120°C, with an output pressure of approximately 0.6 MPa per stage and a head of 60 meters. Widely used in environmental protection, shipbuilding, petroleum, pharmaceuticals, food, chemical, and paper industries, it is often referred to as the "MONOPUMP" in international markets. The G-type single-screw pump features a compact structure, fewer components, small size, and easy maintenance. Its rotor and stator are wear-prone parts with simple structures, making them convenient for assembly and disassembly. This pump exhibits strong adaptability to media, capable of handling high-viscosity substances (up to hundreds of thousands of centipoise or higher) and media with high solid content (40% to 70%). It can also transport media containing particles or fibers, with particle diameters up to 30 mm and fiber lengths reaching 150 mm. Additionally, it is suitable for conveying sensitive or shear-sensitive media. The pump operates smoothly, characterized by steady flow, stable pressure, no pulsation, and low noise. Its flow rate is directly proportional to the rotational speed, ensuring excellent variable regulation capability. G-type single-screw pump has strong self-priming capability, with a suction lift exceeding 6 meters of water column, and can be installed at any angle. It operates within a wide temperature range, with the standard model capable of reaching up to 120°
