Hydraulic Gear Pumps is designed with dual interlocking gears which are of different sizes and one of them rotates inside the other reasoning one. These are mainly used in order to pump high viscosity of fluids like oil, paints, resins or foodstuffs. In the cases where exact and accurate high pressure and dosing is needed, these pumps prove too be highly beneficial. Gear pumps are also widely used in chemical installations to pump high viscosity fluids. Hydraulic Gear Pumps makes use of the meshing of gears in order to pump fluids by displacement. These are believed to be one of the most common kinds of pumps that are used for hydraulic fluid power applications.
