  • The Gorman Rupp Industries (GRI) 15650-119 Magnetic Drive Centrifugal Pump has 1/2 MHB x 1/2 MHB Ports and is closely coupled to a 115 Volt Motor. This pump has a maximum head of 5.5 feet and a performance range of up to 3.5 GPM. The operation of this magnetic drive centrifugal pump is similar to that of a standard centrifugal pump, except that the motor shaft seal is not present. Magnetic drive pumps work by driving an impeller and magnet assembly with a drive magnet attached to the motor shaft to isolate the pump body from the motor. A drive magnet transmits motor torque to the impeller assembly via a plastic housing. The motor drive magnet is separated from the fluid being pumped by the plastic housing. 

    Shaft seal failure leaks are no longer a problem. The end result is a more efficient seal-less centrifugal pump that will not leak and can operate continuously for up to 50 thousand hours. Pump bodies and impellers are designed to produce the efficient flow and head characteristics required in today's applications. The hydraulic designs, when combined with motors designed specifically for the pump end, result in less power consumption for the work performed. 

    These GRI Centrifugal pumps are designed to transfer both corrosive and non-corrosive fluids while maintaining maximum hydraulic efficiency. Mag-Drive GRI Centrifugal pumps are not self-priming and must be used in situations where there is a flooded suction. These pumps must never be run dry. The Maximum Fluid Temperature for this mag drive pump is up to 203 degrees F to ensure maximum life (95 degrees C).


    Marine applications, laser systems, alternative energy systems, public transit systems, chillers, devices that circulate glycol or water, alternative power units, thermal heating and cooling systems, printing tools, beverage dispensers, recreational vehicle production, cooler systems, medical machinery and systems, fuel cells, coolant systems, and hydronic systems are examples of typical applications for this pump. Special combinations of chemically inert plastic are used in the construction to handle the most aggressive chemicals. With built-in cooling passages designed to use the pumped liquid as a lubricating coolant, the impeller shaft and bearing system handle the inherent friction and motor heat. As standard materials for each magnetic drive pump line, these pumps use ceramic shafts with either Teflon or ceramic thrust bearings.
