Gorman Rupp Super U Series

Self-Priming Centrifugal Pumps
Gorman-Rupp Pumps: Innovation, Improvement and Superior Products


Super U Series® pumps are the most efficient self-priming, solids-handling pumps available. Their unique volute casing design minimizes friction loss and drag. The multi-vane, open impeller is designed for high efficiency, yet can still handle solids up to 1-1/4” (31 mm) in diameter. Super U Series pumps not only deliver high efficiencies (up to 75%), they also perform efficiently across a broad operating range. Varying loads, which cause a pump to operate left or right of its best efficiency point on the operating curve, will reduce operating efficiency by only a very small percentage. The patented external shimless adjustment makes it easy to keep the pump in peak operating condition. Each size pump is available in two different design variations, A or B versions. Super U Series pumps are designed with ease of service in mind. Because they are self-priming, they can be mounted above the liquid being pumped. Should service or maintenance be required, it can be easily performed using common hand tools without disconnecting piping. With no elongated shafts present, routine service can be performed in confined work spaces. Pump Size: 3" (75 mm), 4” (100 mm), 6” (150 mm) Max. Capacity: 94.6 lps Max. Solids: 31.8 mm Max. Head: 63.1 m Materials of Construction: 316 Stainless Steel Fitted, CD4MCu, G-R Hard Iron Fitted
