Description
The Gorman‑Rupp PAH Series® (Prime Aire Plus®) is a heavy‑duty family of self‑priming centrifugal pumps designed to provide enhanced priming performance and reliable solids handling in challenging suction conditions. Building on traditional air‑assist priming technology, the Prime Aire Plus® design enables faster and more efficient evacuation of air from the suction line, resulting in quicker prime establishment and improved operational uptime — especially in applications where frequent dry starts or high vacuum lifts are common.
Designed for use in wastewater treatment, stormwater management, industrial effluent, and other demanding fluid transfer applications, the PAH Series® combines rugged construction with advanced hydraulics to handle wastewater and solids‑laden liquids with minimal clogging. The centrifugal impeller and casing are engineered to pass sizable solids smoothly, reducing maintenance interventions and enhancing overall reliability.
The heavy‑duty pump components — including cast iron or ductile iron casings, durable shafts, and robust sealing systems — ensure long service life in abrasive and corrosive environments. Serviceability is simplified through accessible design features, allowing technicians to perform routine inspection and maintenance with minimal downtime and without disconnecting piping.
