Internal Gear Pumps
Products
Internal gear pumps are positive displacement specially designed to handle high viscosity liquids. They are equipped with casings that can be positioned to meet common piping configurations and they have only two mobile parts that make its maintenance easier.
How It Works
Liquid enters the suction port between the rotor and idler teeth. Liquid travels through the pump between the teeth of the "gear-within-a-gear" principle. The crescent shape divides the liquid and acts as a seal between the suction and discharge ports. The pump head is now nearly flooded, just prior to forcing the liquid out of the discharge port. Intermeshing gears of the idler and rotor form locked pockets for the liquid which assures volume control. Rotor and idler teeth mesh completely to form a seal equidistant from the discharge and suction ports. This seal forces the liquid out of the discharge port.
