2 P R I M I N G - A S S I S T E D P U M P S GORMAN-RUPP SETS A WHOLE NEW STANDARD IN PRIMING-ASSISTED PERFORMANCE Gorman-Rupp, the world s leading manufacturer of pumps, has revolutionized the construction pumping industry. Gorman-Rupp now offers the biggest and broadest range of primingassisted (dry prime) pumps. GORMAN-RUPP OFFERS THE BROADEST RANGE OF PRIMING-ASSISTED PUMPS With sizes from to, heads up to 475 ft., flows up to, GPM and 6" solids-handling capability, Gorman-Rupp s extensive line of hard-working, dependable pumps will tackle everything, including clear liquids, tough solids, and slurry applications.* You can choose the Prime Aire venturi priming system or the Redi-Prime diaphragm priming system. Both offer auto matic priming and repriming. For sewage bypass operations, construction site dewatering or other applications where intermittent flow can be a problem, these dependable, versatile performers help contractors move large volumes of water rapidly, even when sticks, stones, and debris would normally present a problem. All of Gorman-Rupp s priming-assisted (dry prime) pumps are designed and engineered for the most rugged and demanding construction applications and are backed by an industryleading two year warranty. *For larger flows, contact the factory. Additional pump models are available up to in size and up to, GPM. Available in pedestal and SAE pump ends for connection to customer driver.

3 P R I M I N G - A S S I S T E D P U M P S PRIME AIRE PUMPS FEATURE GORMAN-RUPP S UNIQUE PRIMING SYSTEM THIS 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 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. 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, on model PA6C, features a removable coverplate and adjustable/ replaceable wearplate. COMPRESSOR OVER PUMP Several popular models are available in a Compressor-Over- Pump arrangement. This innovative configuration option offers a selfcontained, compact, flexible design while allowing ease of operation and servicing when needed. SOLIDS HANDLING IMPELLER Many Prime Aire pumps feature rugged open-type, two-vane ductile iron impellers that are specifically designed to handle solids and debris up to 4" (12 mm) in diameter. This means fewer clogs and more productivity on tough jobs. ABRASIVE HANDLING SEAL Prime Aire pumps are equipped with oversized, 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 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.

Variable Frequency Drive Engine-Driven John Deere Diesel (liquid-cooled) Deutz Diesel (air-cooled) THIS PRIMING SYSTEM is specifically designed with the environment in mind. By incorporating a positive sealing float box and an integrally mounted diaphragm vacuum pump into the priming assembly, environmental contamination associated with the priming system is virtually eliminated. Models are engineered with highly efficient, enclosed impellers, with some models using double volutes increasing the performance far beyond many competitor s pumps. The Cycloseal design, with its impeller backvanes and unique deflector vanes, assists in removing solids and abrasive materials from the seal area in some cases more than tripling the normally expected mechanical seal life.
