Super U Series®

Up to 75% Efficiency

Gorman-Rupp Super-U Series® pumps are among the most efficient self-priming, solids handling pumps available.  Their unique hydraulic design and smooth wall volute casing minimize friction loss and drag.  The multi-vane, open impeller is designed for high efficiency operation yet can still handle limited solids.  The pumps not only deliver high efficiencies (up to 75%), they also perform efficiently across a broad operating range.  Varying machine loads that cause pumps to operate right or left of its best efficiency point will affect operating efficiency by only a small percentage.  These pumps offer the same reliability and performance as the U-Series with additional features. 

Easy to Maintain

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. All Super U Series pumps can be coupled to a standard NEMA motor, which means there’s no waiting for special motor parts.

Drive Variations

Gorman-Rupp Super U Series® pumps are available as basic units, ready for connection to power or flex-coupled or v-belt driven by an electric motor. When space is limited, flex-coupling often solves confined area issues. V-belt driven configurations offer the advantage of flexibility in speed selection and usually provides maximum operating speed for
