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 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 external shimless adjustment makes it easy to keep the pump in peak operating condition.
