External gear pump 2


The driving middle gear rotates anti-clockwise. Liquid between teeth and housing wall is transported from inlet (green arrows) to outlet (red arrows). The inlet is on grey back cover. The outlet is on green front cover. In comparison with 2-gear pump, this 3-gear pump has double flow rate (like parallel connection of two 2-gear pumps).
