The EVANAIR range of Liquid Ring Vacuum Pumps is designed for performance, reliability, and long-term efficiency in the most demanding industrial environments. Unlike other vacuum technologies that can fail when exposed to moisture, vapour, or liquid carry-over, our liquid ring pumps thrive in these conditions, maintaining continuous and stable vacuum performance even in wet and dirty applications. With a Standard Stainless Steel 304 impeller on all models and minimal maintenance requirements, they are a trusted choice for industries that cannot afford downtime or contamination risks. For applications requiring even greater resistance to corrosion and harsh process conditions, EVANAIR also offers a full stainless steel construction option across the liquid ring range.

One of the defining features of the EVANAIR Liquid Ring Vacuum Pump is its simplicity and practicality. Built with a mono-block, close-coupled design, these pumps are compact, robust, and supplied as plug-and-play units, making installation and integration quick and hassle-free. Whether operating in high-humidity environments, saturated gas handling, or continuous-duty cycles, they deliver reliable suction without efficiency loss. While most of our stock models are single-stage units, we also provide two-stage configurations on special order, extending vacuum levels and application possibilities. The range covers a wide selection of flow rates and operating pressures, ensuring there’s a pump to match nearly any industrial requirement.

With rugged construction, compact design, and proven efficiency, EVANAIR Liquid Ring Vacuum Pumps deliver dependable performance where other technologies fall short.
