Gear pumps are positive displacement pumps that use interlocking gears to transfer fluids by trapping them between the teeth of the gears and the pump casing. They are known for their precise flow control, high-pressure capabilities, and ability to handle viscous fluids like oils, adhesives, and polymers. These pumps are commonly used in industries such as lubrication, chemical processing, and hydraulic systems, where consistent and accurate fluid delivery is essential. Gear pumps are valued for their durability, compact design, and efficient operation in handling a wide range of fluids.
