Gorman-Rupp’s integrally mounted diaphragm priming assembly is an option on select 4-inch, 6-inch, 8-inch,10-inch and 12-inch Prime Aire and Prime Aire Plus pump models. An alternative to Gorman-Rupp’s venturi/compressor priming system on its priming-assisted pump models, the diaphragm primer delivers up to 60 CFM, a vacuum to 30 feet and is rated for temperatures as low as 15° F (-9.4° C). With fewer components, the new primer offers increased efficiency as well as higher lifts. Reversed air flow and thinner values help any liquids entering the primer to escape.
The new primer’s single bearing housing has fewer leak paths and alignment issues compared to dual bearing housing.
