2025 Top 10 oil free screw pump Factory in China

Introduction to Oil Free Screw Pump

Oil free screw pumps are advanced vacuum pumps that operate without the use of lubricating oil in the compression chamber. This design eliminates the risk of oil contamination in the pumped gas, making them ideal for applications where a clean and oil - free vacuum environment is required. They work based on the principle of two intermeshing screws rotating in opposite directions, which continuously suck in, compress, and discharge the gas. Oil free screw pumps offer several advantages, such as high pumping speed, low noise, long service life, and environmental friendliness. They are widely used in industries like semiconductor manufacturing, food packaging, chemical processing, and pharmaceutical production.
