From the performance range of ATOS gear pumps, the flow rate of giant pumps can reach several hundred thousand cubic meters or more per hour, while the flow rate of micro pumps is below tens of milliliters per hour; The pressure of the pump can range from normal pressure to over 19.61Mpa (200kgf/cm2); The temperature of the transported liquid can be as low as -200 ℃, while the temperature of the ATOS gear pump can be as high as 800 ℃ or above. There are various types of liquids transported by pumps, such as water (clean water, sewage, etc.), oil, acid-base liquids, suspensions, and liquid metals. In the production of mechatronic pumps in the chemical and petroleum sectors, most of the raw materials, semi-finished products, and finished products are liquids. However, making raw materials into semi-finished products and finished products requires a complex process. ATOS Atos pumps play a role in conveying liquids and providing pressure and flow for chemical reactions in these processes. In addition, pumps are also used to regulate temperature in many devices.
