Gorman Rupp Prime Aire Series Pumps

Dry Run Capability

This is designed into the Gorman-Rupp priming-assisted system. An oversized, oil-lubricated mechanical seal allows the pump to run dry continuously without damage. For positive, reliable priming time after time, Gorman-Rupp Prime Aire® and Prime Aire Plus® pumps are the ones you can count on.

Compressor Over Pump Arrangement

Several popular Prime Aire and Prime Aire Plus models are available in a “Compressor-Over-Pump” arrangement. This innovative configuration option offers a self-contained, compact, flexible design while allowing ease of operation and servicing when needed.

Impeller Selection

Priming-assisted pump models are available with a variety of impeller types depending on your specific application. Many pumps feature rugged open-type, two-vane ductile iron impellers that are specifically designed to handle solids and debris up to 3" (76.2 mm) in diameter, meaning fewer clogs and more productivity on tough jobs.

Elsewhere, for clean water pumping applications, pumps are available with high-efficiency enclosed impellers. Finally, the PAV3B60 model features our patent-pending Staggerwing® impeller, which enables higher pump efficiency and the ability to pass a 3" spherical solid.

Auto-Start Controls

Auto-start controls automate the pump’s operation in response to liquid levels. The pump starts only when there is water to pump and turns itself off when the water reaches the desired level, so there is never any need to waste fuel and add to costly engine overhauls.
