Graphite pump with power device (typically motor), which is applied to corrosive fluids in transmission or suction. Compared with other non-metal pump, advantage is that not only has excellent graphite corrosion resistance and high thermal conductivity and low coefficient of expansion. So in both strong corrosive, and may appear urgent cold urgent hot occasions, graphite pump has obvious advantages. Graphite pump with corrosive materials only comes in contact with only the use of artificial graphite of parts manufacturing. But the rest, the major component still use metal production. Graphite centrifugal pump Graphite centrifugal pump has been widely applied in corrosiveness liquid transportation. From the characteristic of medium look, most applications in hydrochloric acid industry, followed by sulfuric acid, phosphoric acid (and their salty solutions) system, hydrofluoric acid, benzene and its derivatives, etc; Judging from industrial production field, then including inorganic chemical, organic synthesis, pesticide, metallurgy, chemical, pharmaceutical, light industry, atomic energy, environmental protection, etc. Using temperature mostly in 40 ~ 60 oC, some can amount to 100 ~ 110 oC (hydrochloric acid system), 135 oC (phosphoric acid, even as high as evaporation and concentration) 700-800oC (atomic energy industry melting secret transmission).
