An external gear pump uses two external gears (Figure 1, below) that displace non-lubricating fluids (gears are oil lubricated). The mechanism is usually driven by one of the toothed gears, which in turn drives the other. Three factors are involved in the regulation of flow: volume of cavity between the teeth, speed of gears, and the amount of fluid that slips back to the inlet (tolerance dependant) via the mechanism. There are three main types of external gears: spur, helical and herringbone. helical and herringbone deliver more flow at higher pressure while also being quieter, but may require a greater inlet pressure than spur (EPW, 2012)
