  • Dual displacement external gear pump
    Patent number: 8235691
    Abstract: An external gear pump which has a certain flow rate or volumetric capacity at a given speed can be taken apart and the parts rearranged and assembled into a second pump operating at the same speed with a flow rate or volumetric capacity that is different from the original pump. No new parts are required for the second pump configuration and all original parts are used. With this structure, pumps with different flow rates can be built using fewer parts than conventional designs.
