Gorman Rupp Priming Assisted (Dry Prime) Pumps


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.

Gorman Rupp PA Series Silent Pump Engine Driven

Portable, sound-attenuated pumping systems with solids-handling capabilities.

For pumping applications where noise levels must be kept to a minimum, Gorman-Rupp offers a sound-attenuated engine-driven pump unit. Lockable doors prevent unauthorized personnel from tampering with the pump, fuel, engine or controls during unattended service. Fuel capacity allows for a minimum of 24 hours of continuous operation. All units feature a lightweight, corrosion-resistant aluminum enclosure that is acoustically treated to maintain noise levels as low as 63 dBa while operating at full load. Our environmentally engineered Silent Pump units operate much quieter than current industry standards.
