Company History
Gorman-Rupp was established during the early 1930s by J.C. Gorman and Herb Rupp, who believed the pumping industry needed reliable, easy-to-service equipment designed for practical use in the field. From its earliest years, the company has been guided by a philosophy centered on innovation and long service life. Many of the technologies first introduced by Gorman-Rupp—particularly in the self-priming centrifugal pump category—became foundational pumping methods that shaped modern pump station design.
Over the decades, Gorman-Rupp significantly expanded its manufacturing footprint. They added advanced machining, testing and assembly capabilities to support high-volume production and custom-built pumping systems. The company also diversified its product lines to include self-priming and end-suction centrifugal pumps, submersible pumps, priming-assisted pumps, rotary gear pumps and complete packaged pumping systems designed for municipal and industrial service.
A major milestone in Gorman-Rupp’s evolution was the development of ReliaSource® packaged pumping systems. These are fully engineered, above-ground pump stations designed and assembled by the company. They are shipped ready for installation with integrated pumps, controls, enclosures and system accessories.
Today, Gorman-Rupp maintains a strong focus on reliability, maintainability and long-term lifecycle value. Its products are supported by a global distributor network, comprehensive service resources and a customer support model built to ensure uptime and sustainable performance well after installation.
Product Overview
Self-Priming Centrifugal Pumps
Designed for above-ground installation, these pumps are easy to install, service and maintain. Their configuration eliminates the need to enter wet wells or handle extended shaft assemblies, making them ideal for wastewater, wastewater bypass, industrial effluent transfer and general dewatering.
Rotary Gear Pumps
Gorman-Rupp rotary gear pumps offer precise, positive-displacement pumping for viscous, lubricating, and specialty fluids across industrial and petroleum applications. Their versatility supports a wide range of operating viscosities and temperature conditions.
Submersible Pumps
Available for both clean water and solids-handling duties, Gorman-Rupp submersible pumps offer reliable submerged operation with silent performance and minimal space requirements. These pumps are also available as part of packaged system configurations.
Priming-Assisted Pumps
Built for applications with intermittent flow or fluctuating suction conditions, priming-assisted pumps feature technology that allows continuous dry running without damage. This reduces environmental exposure and simplifies setup in temporary or remote locations.
Standard and End Suction Pumps
Gorman-Rupp produces a wide range of heavy-duty centrifugal pumps engineered for extended service life, high efficiency, and reduced maintenance in industrial process, HVAC, water supply and transfer applications.
Explosion-Proof & Specialty Pumps
These pumps are purpose-built for hazardous and volatile liquid environments, ensuring safety and compliance in regulated industrial operations.
OTS Utility Pumps
