The Gorman-Rupp Super U Series® self-priming pumps are among the most efficient self-priming, solids-handling pumps on the market. Designed for industrial applications requiring consistent reliability and uptime, these pumps achieve up to 75% hydraulic efficiency, ensuring superior performance and energy savings across a wide operating range.
Key features include:
- A unique volute casing that minimizes friction losses and drag, improving hydraulic efficiency.
- A multi-vane, open impeller capable of handling solids up to 1-1/4 inches (31 mm), balancing solid-handling capability and high performance.
- External shimless adjustment system that allows for quick and accurate impeller clearance tuning—no need to disassemble belts, shafts, or couplings, helping extend component lifespan.
- The exclusive Gorman-Rupp cartridge seal, double-floating and oil-lubricated, resists abrasive wear and provides a long-lasting sealing solution for tough environments.
- Tool-free maintenance: A removable cover plate with easy-grip handle enables quick inspection and debris removal without disconnecting the piping system.
- Removable rotating assembly: Enables simple shaft and bearing maintenance by removing just four bolts.
The Super U Series pumps support various drive options, including direct connection, flex-coupling, or v-belt driven electric motors. All models are compatible with standard NEMA motors and can be integrated into ReliaSource® packaged systems for turnkey solutions.
With dimensional interchangeability with Super T Series® pumps and an industry-leading 5-year warranty, the Super U Series is an optimal choice for heavy-duty industrial applications where performance and maintenance efficiency matter most.
