Principles for selecting sealing gaskets for gear pumps

The selection principle for gear pump gaskets is that for situations with low requirements, they can be selected based on experience alone, and can be replaced if they are not suitable. But for those occasions with strict requirements, such as explosive, highly toxic, and flammable gases, as well as highly corrosive liquid equipment, reaction tanks, and transportation pipeline systems, the selection should be based on the working pressure, working temperature, and the corrosiveness of the sealing surface and sealing medium. Generally speaking, non-metallic soft honey gaskets are used for gear pumps at room temperature and low pressure; When subjected to medium pressure and high temperature, metal gaskets or a combination of metal and non-metal gaskets should be used; When there are significant fluctuations in temperature and pressure, choose elastic or self tightening gaskets; Under low temperature, corrosive media or vacuum conditions, high-performance gaskets should be considered.
