GR series internal meshing rotor pump is a product specially developed and designed for the wind power industry. It is used in the lubrication and cooling of gearboxes. It procures high-precision tooth grinding technology with an accuracy of up to level 4, improves gear hardness through carburizing and quenching process, and provides products with more reliable, more stable performance and longer service life. At the ambient temperature of -52°C, it still has a strong self-absorption ability to avoid poor oil absorption. Since 2016, it has been serving the wind power industry and supporting mechanical pumps for gearboxes.
