Stainless steel arc gear pump with the international community is considered the most advanced delivery pump that continuous contact with the gear, dual arc and sinusoid composite into the tooth can be completely out of the involute gear pump. Won a major national scientific and technological achievements of the project, and by the State Board of Education Science and Technology Progress Award. Arc gear point continuous contact between two meshing tooth profile, does not produce the phenomenon of trapped oil to thoroughly solve the involute gear pump to cause pump vibration, noise, due to trapped oil phenomenon bearing the load increases. Arc gear pump with high efficiency, low noise, and has a good energy saving effect. Botou gear pump continue to increase investment in science and technology, to promote a high level of competition of the industry, and promote the development of China's national pump to improve the living standards of employees, to increase employment opportunities, to set an example for the revitalization of the regional economy has been the responsibility and obligation of our growth journey. We want the distance charm to create a first-class arc gear pump.
