Vooner FloGard VG7C-M Single Stage Liquid Ring Vacuum Pump

The Vooner FloGard VG7C-M is a robust single-stage liquid ring vacuum pump designed for industrial applications requiring reliable vacuum generation, such as in paper mills, chemical processing, food and beverage, and wastewater treatment. Utilizing a liquid ring principle, it creates a vacuum by rotating an impeller within a cylindrical casing filled with sealing liquid, typically water, which forms a ring and compresses gas. Key features include high efficiency in handling wet or contaminated gases, low maintenance due to its simple design with no internal metal-to-metal contact, and the ability to achieve deep vacuum levels up to 29 inches Hg. Advantages over similar products like Nash or SIHI pumps include superior corrosion resistance in the cast iron model (indicated by 'C'), compact footprint for easy integration, and enhanced durability for continuous operation. Drawbacks may include higher water consumption and the need for a consistent sealing liquid supply. This model, with a 2023 test date, appears in excellent used or refurbished condition, offering cost-effective performance for medium-capacity vacuum needs (around 150-250 ACFM). It excels in humid environments but may require additional filtration for abrasive particles.
