External Gear Pumps

External Gear Pumps are a type of Positive Displacement Pumps. Their basic machinery consists of double gears fixed inside a casing with interlocking teeth. These connected gears are linked to a motor. The motor powers the circulation of the gears in opposite directions from each other. The movement of the gears pulls the fluid inside the pump. The liquid moves along the gaps in the teeth of the gears, and gets disposed off from the pump from the discharge end. These kinds of pumps are a perfect choice for handling the transfer of viscous and abrasive fluids. Roto Gear Pumps are actively used in petrochemical, chemical, oil, gas and FMCG industries.

Gear pumps are one of the most common types of positive displacement pump. These pumps operate by an unchanging volume of fluid passing between the teeth of two meshing gears and their casing at a constant rate. As the gears rotate and the meshed teeth separate, a partial vacuum is formed that fills with fluid. As the gears continue to rotate, they trap the liquid and move it around the casing from the suction to the discharge point.
