Reliable, efficient, and built for demanding applications
The Gorman-Rupp 6400 Series™ end suction centrifugal pumps are built for industrial and municipal applications, delivering superior durability, easy maintenance, and high-performance solids handling. Whether moving wastewater, industrial waste, or agricultural fluids, these pumps provide reliable operation for years to come.
The 6400 Series™ is a standard end suction centrifugal pump designed for clean liquids or those containing solids. It offers reliable performance in wastewater treatment, industrial plants, mining, construction, and agricultural applications .
These pumps feature the Eradicator® and Eradicator® Plus solids management systems, which reduce clogging by breaking down stringy materials, wipes, and debris before they enter the pump .
Models range from 2” to 8” sizes, with maximum capacities up to 620 m3/h and heads up to 52 meter.
They are used across wastewater treatment plants, industrial facilities, construction sites, mining operations, and agriculture—for example in sludge transfer, slurry handling, or lagoon systems.
All 6400 Series™ pumps are constructed from ductile iron, offering excellent durability and corrosion resistance in harsh environments.
Yes. Many rotating assemblies are interchangeable with the Super T Series®, reducing spare parts inventory and simplifying maintenance .
The exclusive double-floating, oil-lubricated mechanical seal is designed to handle abrasive and trash-laden fluids, increasing seal life and uptime.
Eradicator® Plus includes a thicker G-R Hard Iron wearplate and an oversized lacerating tooth, specifically for cutting and shredding organic solids in extreme-duty pumping conditions .
Options include two-vane, multi-vane, slim-line, and continuous single-vane impellers—each optimized for different efficiency or solids-handling needs .
Yes. The vortex models feature precision-balanced impellers for fibrous or abrasive materials, reducing hydraulic pressure on the seal and preventing clogging.
Depending on the model, the 6400 Series™ can pass solids up to 4 inches (102 mm) in diameter.
The removable rotating assembly allows quick access without disturbing piping, reducing downtime and improving serviceability.
Yes. Every 6400 Series™ pump is covered by a five-year warranty, among the best in the industry.
Gorman-Rupp provides global service, fast parts delivery—often within 24 hours—and technical documentation such as CAD drawings and performance curves.
It delivers low lifecycle costs, high reliability, and unmatched solids-handling capability—making it a long-term, cost-effective solution for tough environments.
