What are the characteristics of chemical pump?

　　What are the characteristics of chemical pump? Chemical production process features: High temperature, high pressure, flammable, explosive, corrosive, toxic. So the choice of chemical pump, first of all to consider the pressure, especially the entrance is also pressure. Second, in high-temperature areas, to consider the choice of high-temperature materials; and then the sealing performance is good, generally mechanical seal, or shielding pump; and to consider the corrosion of the media, choose the appropriate materials.
