Gorman Rupp

Vacuum assist pumps

VACUUM ASSIST

The Prime Aire system uses a venturi and a compressor, which eliminates the leaks associated with traditional vacuum-assisted pumps. This unique system not only reduces environmental concerns on sewage bypass operations and other 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.

Gorman Rupp Vacuum assist pump benefits

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

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. This means fewer clogs and more productivity on tough jobs. For clean water pumping applications, pumps are available with high-efficiency enclosed impellers.

And, model PAV3B60 features our patent-pending Staggerwing® impeller. The Staggerwing technology enables higher pump efficiency and the ability to pass a 3" spherical solid.

STANDARD AUTO-START CONTROLS

This feature allows you to start and stop the pump in response to a liquid level. The pump starts only when there is water to pump and turns itself off when the water reaches the desired level. There is never any need to waste fuel and add to costly engine overhauls.
