Gorman Rupp Prime Aire Series

Self-Priming Centrifugal Pumps


With a variety of sizes and operating ranges, Gorman-Rupp’s extensive line of Prime Aire® and Prime Aire Plus priming-assisted (dry prime) pumps are hard-working, dependable and ready to tackle the toughest applications including large solids and slurries. The Prime Aire and Prime Aire Plus system uses a venture 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 and PAH 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. Pump Size: 4” (100 mm), 6” (150 mm), 8” (200 mm), 10” (250 mm), 12" (300 mm), 14" (350 mm), 16” (400 mm) Max. Capacity: 946.4 lps Max. Solids: 101.6 mm Max.
