Description
The Gorman-Rupp RD & RS Series pumps, featuring the patented Roto-Prime® self-priming system, are engineered for reliable and efficient handling of wastewater, sewage, slurries, and other solids-laden liquids in municipal and industrial environments. These pumps combine advanced self-priming technology with robust construction to deliver high performance in applications where dependable prime recovery and solids passage are essential.
The hallmark of the RD & RS Series is the Roto-Prime® technology — a rugged, internally mounted self-priming mechanism that allows the pump to evacuate air from the suction line and maintain prime automatically, even in the presence of air pockets or unfavorable suction conditions. This eliminates the need for external priming devices or special foot valves, reducing complexity and maintenance requirements.
Built with heavy-duty materials such as cast iron casings, wear-resistant impellers, and robust sealing systems, the pumps are engineered to withstand abrasive service and extended duty cycles. The RD Series typically features a standard solids-handling design, while the RS Series includes enhanced solids management options like spiral-cut impellers and vortex-style hydraulics for improved handling of stringy or fibrous materials.
