Gear Pumps

Gear Pumps

A gear pump uses the meshing of gears to pump fluid by displacement. They are one of the most common type of pumps for hydraulic fluid power applications. Gear pumps are also widely used in chemical installations to pump fluids with somewhat higher viscosity. There are two main designs: external gear pumps which use two external spur gears, and internal gear pumps which use an external and an internal spur gear. Gear pumps are positive displacement meaning they pump a constant amount of fluid for each revolution.Some gear pumps are designed to function as either a pump or a motor. (taken from: Wikipedia)
