Pentair Aurora - Edwards Gear Pumps 20 Series

How Edwards Gear Pumps Work

The Edwards gear pump develops flow by carrying fluid between the teeth of two meshed gears. One gear is driven by the drive shaft and turns the other. The pumping chambers formed between the gear teeth are enclosed by the pump's housing and the side plates.

A partial vacuum is created at the inlet as the gear teeth unmesh. Fluid flows in to fill the space and is carried around the outside of the gears. As the teeth mesh again at the outlet, the fluid is forced out. High pressure at the pump's outlet imposes an unbalanced load on the gears and their bearing support structure.
