Gear Pump
Gear pumps are positive displacement pumps that transfer fluid by the meshing of rotating gears. They are widely used in hydraulic systems and industrial applications, especially for pumping high-viscosity fluids with steady and precise flow.
Overview
A gear pump is a type of positive displacement pump that moves fluid by trapping it between the teeth of rotating gears. As the gears mesh and rotate, fluid is carried from the inlet to the outlet at a constant flow rate.
Operating Principle
Fluid enters the pump as the gears unmesh at the inlet side. The fluid is trapped between the gear teeth and the pump casing, then transported around the casing to the discharge side where the gears mesh again and force the fluid out.
