Gorman-Rupp PA Series Priming Assisted Pumps

Gorman-Rupp's priming assisted pumps are the perfect solution for sewage bypass operations, construction site dewatering and other applications where intermittent flow can be a problem. These units feature a patented positive priming system that virtually eliminates leaks, reducing environmental concerns and giving the unique capability to operate under flooded-suction staging conditions.

Prime Aire® Pumps feature Gorman-Rupp's patented priming system. The system uses a venturi and compressor, eliminating the leaks associated with traditional vacuum-assisted pumps. 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 pumps are the ones you can count on.

• Dry Run Capability: A dry run capability is designed into the Prime Aire® 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 pumps are the ones you can count on.

• Dual-Suction Side Capability: Model PA6C features a removeable cover plate and adjustable/replaceable wearplate.
  Compressor-Over-Pump: Several popular Prime Aire® models are available in a "Compressor-Over-Pump" arrangement. This innovative configuration offers a compact, flexible design while allowing ease of operation and servicing when needed.

• Abrasive Handling Seal: Prime Aire® pumps are equipped with oversived, mechanical, oil-lubricated, double-floating, self-aligning seals with silicon carbide rotating and stationary faces that are designed to take the wear and tear of pumping solids, slurries and other abrasives.

• Standard Auto-Start Controls: Auto-Start control starts and stops the pump in response to a liquid level. The pump only starts 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.
