Gear Pumps
Gear pumps, or rotary gear pumps, are positive displacement (or fixed displacement), meaning they pump a constant amount of fluid for each revolution. They consist of at least two separate and rotating gears with inter-meshing teeth. As these meshed teeth separate, they create a partial vacuum which is filled by the fluid being pumped. As the gears then continue to rotate the fluid becomes trapped and is carried around the casing to the discharge side of the pump. Here as the gear teeth begin to re-mesh the fluid is ejected creating a pumping action. Gear pump brands Oberdorfer Hypro Shertech
