Gear Pump Overview:

Gear pump can be divided into two broad categories, external gear and internal gear, some developed countries abroad occupies a large proportion in the production of gear pump in the hydraulic pump.Compared with external gear pump, the internal gear pump with its small size, light weight, low noise, good self-priming performance, and the advantages of small flow pulsation and cherished, its production occupies a large proportion in the total output of the gear pump.Some developed countries internal meshing and external gear pump's output is close to 1:1.
Can be divided into the ordinary gear pump gear pump according to the purpose, special gear pump and transport with high parameters of polymer gear pump.Most ordinary gear pump used to transport oil liquid or used in the hydraulic system, therefore, also known as the pump or pump.Special gear pump can be used to transport high viscosity liquid, working pressure is usually not more than 1.5 Mpa, widely used in petrochemical, textile, food, paint and other industries.Polymer conveying with gear pump are used to transport the chemical process of high temperature and high pressure, sticky polymer.From the ordinary gear pump to the polymer conveying pump, their design and manufacturing difficulty is escalating as harsh work conditions.
