Gear Pumps

Contamination-Resistant, High-Speed, Reliable, and Stackable.

A gear pump consists of a housing with inlet and outlet ports, and a pumping mechanism made up of two gears. The action of the gear teeth meshing, and un-meshing generates an increasing and decreasing volume.

At the inlet where gear teeth unmesh (increasing volume), fluid enters into the housing. This fluid becomes trapped between the gear teeth, and the housing and is then carried to the other side of the gear causing the gear teeth to mesh (decreasing volume) and forcing the fluid out into the system.

Gear pumps are generally an unbalanced design and are either an external (gear-on-gear) or internal gear (gear-within-gear) design.
