The Prime Aire pumps from Gorman-Rupp use a venture and a compressor to eliminate the leaks associated with traditional vacuum-assisted pumps. The system reduces environmental concerns on sewage bypass operations and other environmentally hazardous liquids, but it also enables the pumps to operate under flooded suction conditions without leaking. The positive priming of the Prime Aire is well suited for applications involving long suction lines, intermittent flows or large volumes of air in the liquid being pumped. In addition, dry run capability is designed into the Prime Aire system.
