A gear pump is any type of rotary positive displacement pump consisting of gears where the pumping results from the unmeshing and remeshing of gears. The liquid is carried between the gear teeth by the rotation of the pump. Common types of gear pumps include internal gear, external gear, and gerotor.

Again, common types of gear pumps include rotary positive displacement pumps like the internal gear, external gear, and gerotor pumps.

A type of gear pump with a drive gear featuring inward facing teeth called a rotor. This rotor turns an offset gear with fewer outward facing teeth called an idler. A crescent shape protruding from the head of the pump creates this offset and seals the pumping cavities formed between the gear teeth. Click here to view our How it Works video on this subject.

External gear pumps are a type of rotary positive displacement gear pump that features two identical external gears where one gear is the drive gear and one is the driven. The liquid is transferred from between the gear teeth by the rotation of the pump. Click here to view a video on this subject.

A type of internal gear pump that is driven by the idler gear and does not include a crescent. Click here to view our How it Works video on this topic.
