MalaysiaGear Pump Manufacturers
External Gear Pumps are a type of Positive Displacement Pumps that operate with the help of a couple of gears rotating in clockwise and anti-clockwise directions. One of these gear’s functioning is propelled by a motor. The gears are fitted together with intermeshed teeth inside the casing. The movement of one gear leads to the movement of the other in the opposite direction. The vacuum created between the teeth of the gears owing to their movement is filled with the liquid that is pulled inside the pump. The liquid gets carried through the suction end to the discharge end of the pump.

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.
