UDi 4-16 Highly Reliable Vacuum Pumps for Harsh Environment

The UD i Series is a vacuum pump with high reliability and easy maintenance for cutting-edge scientific experiments. Its core components are treated with anti-corrosion technology to prevent the product from being eroded by corrosive substances. It adopts shielding technology and magnetic drive technology to achieve static sealing. This solves the oil leakage problem caused by traditional dynamic sealing structures for users and ensures the reliable operation of the vacuum pump in environments with high water vapor and highly corrosive gases. Equipped with a gear pump with forced lubrication, an automatic anti-oil return structure, and a built-in high-quality oil mist filter, it provides you with a clean, quiet and comfortable vacuum environment. Meanwhile, the CE-certified DC brushless motor and one-touch ECO function enable high-efficiency energy conservation. The UDi Series vacuum pump is especially suitable for fields such as scientific research, laboratories, medical and phar
