Sewage and wastewater demand reliable, high-performance pumps. Whether for municipal or industrial applications, handling these fluids is a challenge for any pump.
With Gorman-Rupp, the inventor of the original trash pump, you benefit from over 90 years of expertise in tackling the toughest wastewater challenges.
Our pumps are used in lift stations, wastewater treatment plants, and as mobile units for temporary bypass operations.
Wastewater naturally contains solids that can cause clogging, wear, and high maintenance costs. But not with Gorman-Rupp pumps. Solids handling is our specialty. Our proprietary Eradicator® solids management system prevents clogging from fibrous materials like plastic bags and sanitary wipes.
Whatever your wastewater challenge, Gorman-Rupp has the right pump solution. Rely on our 90+ years of experience and reduce your pump risks with Gorman-Rupp trash pumps.
Reliable, efficient, and easy to maintain- Gorman-Rupp self-priming pumps handle liquids containing air, solids, and debris while keeping maintenance hassle-free. Thanks to automatic repriming, they continue running even if the suction line is completely empty. Their above-ground installation ensures easy servicing, eliminating the need for confined space entry.
Designed for demanding conditions, Gorman-Rupp dry-prime pumps automatically remove air from the suction line, allowing for immediate pumping without manual priming. They deliver high flow rates, large solids handling, strong suction power, and energy-efficient operation- ideal for tough applications that require reliability and quick deployment.
The most widely used pump type, centrifugal pumps operate with rotating impellers to create a steady fluid flow. Known for their simple design, minimal moving parts, and smooth operation, they provide a cost-effective solution for general fluid transfer. Available in various sizes and materials, Gorman-Rupp standard centrifugal pumps ensure high efficiency and consistent performance.
A ready-to-use pumping solution for maximum flexibility. Whether electric-driven, diesel-powered, or battery-operated, our pump sets come pre-assembled for quick deployment. Available in both mobile and stationary configurations, they offer easy setup, reliable operation, and long service life.
More than just a pump- Gorman-Rupp pump systems are fully engineered solutions integrating self-priming pumps, protective enclosures, and intelligent self-cleaning technology. Designed for above-ground installation, they provide seamless, low-maintenance operation while eliminating the need for deep pits, submerged components, and expensive servicing.
Municipal sewage applications typically use self-priming pumps, prime assisted (dry-prime) pumps, and standard centrifugal pumps. Self-priming pumps are widely used because they handle raw sewage containing solids and debris while staying installed above ground for easy access. The choice depends on the medium, flow rate, head, and solids content of the application.
Raw sewage carries fibrous material such as plastic bags, sanitary wipes, rags, and other debris. These materials can wrap around the impeller and block the pump, leading to unplanned stoppages and manual cleaning. Pumps for sewage duty therefore need strong solids handling and a clog-resistant hydraulic design.
The Gorman-Rupp Eradicator solids management system is designed to process fibrous materials such as plastic bags and sanitary wipes that commonly cause clogging in sewage applications. It helps keep the pump running on stringy solids that would obstruct conventional designs, which reduces interventions and supports continuous operation. With no moving mechanical parts, the Eradicator solids management system provides a reliable and maintenance free solution.
Gorman-Rupp self-priming pumps are built to handle liquids containing air, solids, and debris. They reprime automatically if the suction line runs empty, so they continue operating during varying inflow conditions without manual intervention. This makes them well suited to lift stations and collection systems where flow fluctuates.
They are used in lift stations and pump stations, at wastewater treatment plants, and as mobile units for temporary bypass operations during maintenance or repairs. Above-ground installation keeps the pump accessible and avoids submerged components.
Above-ground installation gives direct access for inspection, maintenance, and repair without confined space entry. Gorman-Rupp self-priming pumps also feature a front inspection design that opens the pump interior without disconnecting suction or discharge piping or disturbing the drive alignment, which shortens service time in solids-heavy sewage duty.
Yes. Gorman-Rupp offers pump sets in mobile configurations, including the S-Line (diesel) and E-Line (electric), as well as trailer-mounted wheelsets. They are delivered as complete units for quick deployment during bypass operations, emergencies, or as backup capacity.
Gorman-Rupp pump sets are available with electric drive and stage V diesel engines, in both mobile and stationary versions. The drive is selected based on the site, power availability, and whether the duty is permanent or temporary.
Gorman-Rupp offers the Reliasource / SCS, a fully engineered pump system that integrates self-priming pumps with protective enclosures and self-cleaning sump technology. Designed for above-ground installation, it provides low-maintenance, safe and hygienic operation without deep pits or submerged components.
Yes. Gorman-Rupp Europe provides engineering-driven application support for municipal sewage projects, including pump selection based on flow, head, and solids content, system analysis, local assembly, testing, and commissioning assistance from its European facilities.
