PAH Series® priming-assisted pumps are designed and engineered for the most rugged and demanding mining, construction, municipal, agricultural and industrial applications. All Prime Aire Plus® models are backed by an industry leading two-year warranty and are factory tested before they leave our facility.
Prime Aire Plus pumps utilize the same venturi/compressor priming system as the Prime-Aire product line. Increased head, flow and enhanced maintenance features are additional benefits of the PAH Series line. Models feature sizes up to 16” and are suitable for clear liquids and liquids containing large solids. All Prime Aire Plus pumps are configured with EPA Tier compliant engines or premium efficiency motors.
CD4MCu - duplex stainless steel Prime Aire Plus pumps are available in multiple drive variations including basic units, trailer mounted engine-driven units, or skid mounted electric-driven units and are suitable for corrosive and abrasive liquids containing large solids

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.
Popular Prime Aire Plus® 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.
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.
Prime Aire Plus® 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.
Priming-assisted pumps utilize a variety of impeller types based on your specific application. Many models feature rugged, two-vane, ductile iron, semi-open solids handling impellers that handle up to 4” (101.6 mm) diameter solids. For clean water applications, pump models use higher-efficiency enclosed impellers.
