Vacuum dry screw pumps are positive displacement pumps that are designed to operate in rough application conditions. These products do not use any lubricant in the pumping mechanism to seal therefore they are defined as dry compressing machines. Offering a high pumping speed, these pumps can handle a wide range of gases and vapors, ideal for applications in the industrial, chemical, pharmaceutical, and semiconductor industries, among others, where oil-free and contamination-free vacuum is required. They have a compact design and require minimal maintenance, making them a reliable and cost-effective solution for many vacuum applications.
