Dry Screw Vacuum Pumps

  Dry screw vacuum pumps are essential vacuum equipment used in various industries. These pumps operate using a pair of screws that rotate synchronously in opposite directions at high speeds within the pump casing. The rotating screws create suction and discharge, allowing the pump to achieve effective vacuum levels. This article provides an overview of the key features and extensive application range of dry screw vacuum pumps across different sectors. 1. Key Features of Dry Screw Vacuum Pumps High Reliability: Dry screw vacuum pumps have fewer components and no consumable parts, making them highly reliable with a long service life. Ease of Operation and Maintenance: The straightforward design ensures easy operation and maintenance. Excellent Dynamic Balance: With no unbalanced inertial forces, these pumps can run smoothly at high speeds, ensuring stable operation. Strong Adaptability: Due to their forced gas transmission characteristics, dry screw vacuum pumps can main...

 Solvent recovery is a critical process in industries such as chemical, pharmaceutical, petrochemical, and environmental protection. It involves recovering solvents from process streams or waste products for reuse, which helps in reducing costs and minimizing environmental impact. Screw vacuum pumps have become a preferred choice in solvent recovery systems due to their reliability, efficiency, and ability to handle various types of gases and vapors. This article discusses the application of screw vacuum pumps in solvent recovery, In the production of active pharmaceutical ingredients (APIs), the solvent crystallization process involves several critical steps: filtration, washing, and vacuum drying after crystallization. The moisture content of the material is generally around 20%, and the drying temperature should not exceed 80°C. After drying, the moisture content of the API must be reduced to below 0.5%. To remove the solvent from the material effectively, the pressure inside th...
