Dowty Gear Pump 1p,2p

Gear pumps are positive displacement (or fixed displacement), meaning they pump a constant amount of fluid for each revolution. Some gear pumps are designed to function as either a motor or a pump.External gear pumps make use of two external opposing gears (typically spur gears) in transferring the fluid type. Internal gear pumps use one outer ring gear and one internal pinion gear running inside the ring gear. In either type, the gears are contained within a pump housing or body.
