Q-VAC Priming Systems

Q-VAC Priming Systems, a brand of Combined Fluid Products Company (CFP) based in Lake Zurich, Illinois, manufactures purpose-built vacuum priming systems for centrifugal and turbine pumps operating under non-flooded suction conditions. Unlike repurposed industrial vacuum pumps, every Q-VAC system is engineered from the ground up for pump priming reliability, with design choices that directly affect whether a system runs dependably or fails prematurely. Systems are available in simplex and duplex configurations using rotary vane or liquid ring vacuum pump technologies, with fully automatic controls providing continuous priming across every pump in the system while limiting vacuum pump run time. The product lineup includes complete simplex and duplex priming systems, priming valves and accessories, portable priming systems for temporary or field applications, and custom-engineered solutions with 2-D and 3-D CAD documentation. All products are Made in the USA. Q-VAC engineers help customers balance competing priorities including power consumption, maintenance requirements, initial cost, and redundancy. Applications span municipal water and wastewater treatment plants, commercial and naval marine vessels, desalination facilities, power generation plants, steel mills, irrigation systems, aquariums, fountains, landfill leachate, and siphon control installations. The company provides single-source responsibility for complete systems including priming valves and accessories, with customer service staff averaging over 20 years of experience.
