Machinery & Equipment Co. offers used Liquid Ring Vacuum Pumps designed for reliable vacuum generation in chemical, pharmaceutical, food, power, and industrial processing applications. These pumps use a rotating liquid ring—typically water or another compatible fluid—to create vacuum, making them well-suited for handling wet, corrosive, or vapor-laden gas streams with minimal wear and stable performance. Common configurations include single-stage and two-stage designs with a wide range of horsepower and capacity options. Inventory may include manufacturers such as Siemens, Nash, Travaini, SIHI, Flowserve, Kinney, and Croll Reynolds, with units available for applications requiring consistent vacuum levels and robust operation. Contact M&E to review current availability or to source a Liquid Ring Vacuum Pump suited to your specific process and performance requirements.
