With a variety of sizes and operating ranges, Gorman-Rupp’s extensive line of Prime Aire® priming-assisted (dry prime) pumps are hard-working, dependable and ready to tackle the toughest applications including large solids and slurries.
The Prime Aire system uses a venturi compressor priming chamber and priming valve which eliminates the leaks associated with traditional vacuum-assisted pumps. This unique system reduces environmental concerns on sewage bypass operations and also enables the pump to operate under flooded suction conditions without leaking. The positive priming capabilities of the PA Series make it the perfect choice for applications where a large volume of air is in the liquid being pumped, there are intermittent flows or there are long or oversized suction lines. All Prime Aire pumps are configured with EPA Tier compliant engines.
The modular design, featured on several PA Series pump models, enables the addition/removal of a lightweight, aluminum, acoustically-treated enclosure to the standard fuel base. The enclosure provides excellent corrosion resistance and offers a significant reduction in sound levels (68 dBA at 23’).
