The G-type single-screw pump is a device used for transporting liquids, classified as a rotary vane positive displacement pump. It operates by utilizing the meshing of the screw and sleeve to create volume changes in the suction and discharge chambers, thus conveying the liquid. The main working components of the G-type single-screw pump include the sleeve (stator) with a double-headed spiral cavity and the single-headed spiral screw (rotor) that meshes with it within the stator cavity.

Working Principle

As the input shaft drives the rotor to rotate around the stator center through a universal joint, the stator-rotor assembly continuously engages to form a sealed cavity. These sealed cavities move axially at a constant speed with a constant volume, transporting the medium from the intake end through the stator-rotor assembly to the discharge end. Since the screw rotates at a constant speed, the flow rate of the liquid discharge is also uniform.

Application Scenarios

The G-type single screw pump is widely used in various industrial fields, including the petroleum industry, environmental protection, food industry, brewing industry, printing industry, industrial boilers, construction, mining, and the chemical industry. It is particularly suitable for conveying high-viscosity fluids, media containing hard suspended particles, or fibrous media. The G-type single screw pump boasts strong adaptability to media, stable flow rate, minimal pressure pulsation, and high self-priming capability.
