Gear pumps rely on two meshing gears to cause liquid flow. They are precision machines with extremely tight fits and tolerances and are resistant to high pressure differentials. They come in two types: two gears with external teeth or one gear with external teeth and the other with internal teeth.

Gear Pump Manufacturers     clarify that common uses for gear pumps are: moving chemical and petrochemical liquids with relatively high viscosities; supplying fuel to burners or other facilities; and transferring gasoline, kerosene, fuel oil and diesel. They also have hydraulics such as actuators, damper controls and elevators. In addition, they can pump coolants, paints, bleaches, solvents, syrups, glues, greases, asphalt, petroleum and lubricants, and can handle many general industrial applications.

Gear pumps are designed and designed to offer many advantages. These include compact, simple, easy to service, two-way and pulseless flow, self-priming, low net positive suction head requirements, high maintenance averaging time, high pressure and high temperature capability, accurate and accurate metering, and multiple seal availability configurations or no seals Magnetic drive.

The pump can withstand small suspended solids in abrasive applications, but will gradually wear out and lose performance.

Gear pumps are available in a variety of construction materials including cast iron, cast steel, stainless steel, high nickel alloys and lightweight advanced aluminum alloys. They usually have many optional designs, such as tight coupling, wear resistance and compliance with API standards.
