|Gorman-Rupp is pleased to offer an integrally-mounted diaphragm priming assembly as an option on select 4” (100 mm), 6” (150 mm), 8” (200 mm), 10” (250 mm) and 12” (300 mm) Prime Aire® pump models. An alternative to the venturi/compressor priming system on Gorman-Rupp’s priming-assisted pump models, the diaphragm primer delivers up to 60 CFM (1700 LPM), a vacuum to 30’ (9.1 m) and is rated for temperatures as low as 15° F (-9.4° C).
With fewer components, the new primer offers reliability and increased efficiency, as well as higher lifts. Reversed air flow and thinner valves help any liquids entering the primer to escape easily compared to similar systems in the marketplace. The new primer’s single bearing housing has fewer leak paths and alignment issues compared to dual bearing housing alternatives.
