Gorman-Rupp highlights new diaphragm priming system for Prime Aire pumps
By Jenny LescohierFebruary 01, 2023

Gorman-Rupp plans to introduce an integrally mounted diaphragm priming assembly as an option on select 4”, 6” and 8” Prime Aire pump models in its exhibit at CONEXPO-CON/AGG, this March 14-18 in Las Vegas.
An alternative to the venturi/compressor priming system on priming-assisted pump models from Gorman-Rupp, the diaphragm primer delivers up to 60 CFM, a vacuum to 30’ and is rated for temperatures as low as 15° F.
With fewer components, the new primer is designed to offer reliability and increased efficiency, as well as higher lifts. Reversed air flow and thinner valves help any liquids entering the primer to escape easily. The new primer’s single-bearing housing has fewer leak paths and alignment issues compared to dual-bearing housing alternatives.
