What Gorman-Rupp Industries does

Gorman-Rupp Industries (GRI), operating as "GRI Pumps" and "The Pump People," is a division of publicly traded parent The Gorman-Rupp Company (NYSE: GRC). Founded in 1953 and headquartered in a 98,000 sq. ft. facility at 180 Hines Avenue, Bellville, Ohio, GRI designs and manufactures custom-engineered fluid pumps for Original Equipment Manufacturer (OEM) customers across more than ten end markets including medical devices, food and beverage, data center and electronics cooling, transportation, alternative energy, HVAC, laboratory and analytical instrumentation, printing and imaging, appliances, and general industrial. The company employs 11–50 people and runs build-to-order production with over 90% of components sourced from U.S. suppliers.

GRI's product portfolio spans centrifugal pumps (up to 60 GPM), magnetic drive centrifugal pumps (seal-less, leak-free), multiple variants of bellows metering pumps (Standard, Compact, Mini, Pocket, and Dosing — offering ±0.5% to ±1% stroke-to-stroke repeatability), oscillating pumps covered by U.S. Patent 5,567,131, gear pumps, and the flagship Integrity Series of brushless DC magnetic drive circulation pumps (INTG1, INTG3, INTG6, INTG8) ranging up to 39 GPM and IP68-rated. Since 2016, GRI has produced motors robotically in-house for the Integrity Series, providing vertical integration and deep customization. The company holds ISO 9001:2015, ISO 14001:2015, RoHS, and FDA/NSF material certifications relevant to medical, food/beverage, and EU OEM applications.

GRI's business model is OEM-embedded and quote-based: there is no off-the-shelf inventory and no public price list. Pumps are custom-configured or custom-engineered to OEM specifications (flow, pressure, voltage, materials, port configuration, control protocol) with pricing determined through direct engagement with a territory-based sales team (International, Western, Eastern) supported by an authorized distributor network spanning North America, Africa, Asia, Europe, South America, and Australia/Oceania. Free sample pumps are offered to qualified OEMs to accelerate design-in. Multi-year contracts underpin recurring revenue once a pump is qualified into an OEM's equipment.
