2020-9-9 Rate of flow (Q) – The rate of flow of a gear pump is the quantity of fluid actually delivered per unit of time, including both the liquid and any dissolved or entrained gases, at stated operating conditions. In the absence of any vapor entering or forming within the pump, rate of flow is equal to the volume displaced per unit of time, less slip.

More### Gear Pump - an overview ScienceDirect Topics

2012-3-3 A 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.
