Liquid ring vacuum pumps AWS, AWD & AWL series

Thanks to a tough construction and proven operating principle, AWS, AWD & AWL liquid ring vacuum pumps from Atlas Copco are used in the most demanding environments across all sectors from food processing to petrochemical to construction.

AWS, AWD & AWL series – Suitable for a wide range of applications

The new AW series of standard liquid ring vacuum packages are perfect for use in humid, dusty and dirty environments commonly found in industrial processes. The pumps, which have a simple and study design, reliably deliver vacuum to a whole range of industries including food & beverage, dairy, mining, chemicals, oil, steel, cement, plastics, textiles and food processing. Liquid ring pumps are equipped with a fixed blade impeller located eccentrically within a cylindrical casing. As the impeller rotates, liquid (usually water) is thrown out by centrifugal force to form a liquid ring around the circumference of the casing, sealing the tips of the impeller and creating separate enclosed gas chambers between each blade. As a result of the eccentric position of the impeller, these chambers vary in volume as the shaft rotates, having the effect of drawing in and compressing process gas. The AW liquid ring vacuum pumps are available for both single and two stage pumps. AWS single stage liquid pumps are optimized for operation above 200 mbar(a), making them perfect for applications such as filtration or wet conveying, with an ultimate pressure of 30 mbar(a). Our liquid ring vacuum pumps are offered as plug & play modules or engineered systems for complex duty applications in a number of configurations and are suitable for operation in once through, partial recirculation or total recovery. For partial or total recovery systems the pump package components are offered with stainless steel wetted parts as standard, irrespective of the materials of construction of the pump. The AW liquid ring vacuum pumps are available for both single and two stage pumps. Our liquid pumps are optimized for operation above 200 mbar(a), making them perfect for applications such as filtration or wet conveying, with an ultimate pressure of 30 mbar(a). They are the perfect solution for cyclical pump down applications such as evacuation, impregnation or sterilization. AWD dual stage pumps are finely tuned machines dedicated to providing consistent high performance at operation pressures below 200 mbar(a). The two synchronized pumping chambers work in series to enable optimal performance on continuous critical process applications such as bottling, degassing, & solvent recovery.

Liquid ring vacuum pumps deliver sustainable productivity in the harshest environments including:
