Discover the epitome of efficiency with our stationary screw vacuum pumps, engineered to deliver high vacuum performance coupled with exceptional energy and cost savings. These state-of-the-art pumps feature variable frequency capabilities, making them ideal for a diverse range of industries including foam, ceramics, and brickworks. Available in 11kW, 15kW, 37kW, 45kW, and 55kW models, our innovative technology serves as a superior replacement for traditional water ring pumps, ensuring enhanced operational productivity and reliability.
Working Principle
The Sanzhi Stationary Screw Vacuum Pump harnesses the power of dual screws, which rotate synchronously and at high speeds in reverse directions within the pump casing. This innovative design facilitates both suction and exhaust functions. The screws undergo meticulous dynamic balance correction and are supported by robust bearings, ensuring they are securely mounted within the pump casing. Given the precise clearance between the screws, the pump operates seamlessly with no internal friction, resulting in smooth functioning and minimal noise. This vacuum pump excels in environments where it is essential to extract substantial amounts of water vapor and small quantities of dust-laden gases. It boasts a high vacuum limit, reduced power consumption, and energy-saving features. Additionally, it is maintenance-free, making it an ideal choice for industries such as pharmaceuticals, chemicals, semiconductors, and food packaging, where a clean and efficient vacuum is paramount.
