GRI Pumps (Gorman-Rupp Industries) - Bellows Metering Pumps

Bellows metering pumps operate on a positive displacement principle. Pumps are designed to displace both corrosive and noncorrosive fluids. Accurate to ± 0.5% from stroke to stroke, when pump is set 50% to 100% of full stroke. Discharge pressure is maintained over the entire flow range of the pump. (read more)

GRI Pumps (Gorman-Rupp Industries) - Centrifugal Pump

Centrifugal pumps are designed to transfer both corrosive and non-corrosive fluids at maximum hydraulic efficiencies. Centrifugal pumps are not self-priming and must be used in applications where flooded suction exists. These pumps can not be run dry. (read more)

GRI Pumps (Gorman-Rupp Industries) - Oscillating Pumps

Oscillating pumps are self-priming, corrosion resistant, have no dynamic seals and are constructed from FDA accepted materials. Typical applications include film and microfilm processors; litho and graphic arts plate processors; detergent dispensing, chemical mixing, medical, scientific and laboratory equipment. (read more)
