External-gear pumps are rotary, positive displacement pumps that can handle thin and thick fluids in both pumping and metering applications. Distinct from internal-gear pumps which use “gear-within-a-gear” principles, external-gear pumps use pairs of gears mounted on individual shafts.
Common external gear pump applications include, but are not limited to:
Various fuel oils & lube oils
Chemical additive & polymer metering
Chemical mixing & blending (double pump)
Industrial & mobile hydraulic applications
Low volume transfer or application
