HCLL9DJUE

Product features:

The series pump is sealed with dry gas, and the flushing scheme often adopts Plan11/21+Plan72+76. The medium will not leak into the atmospheric environment. Usually, minor internal leaks need to be discharged into the flare system. When used in media with saturated vapor pressure lower than atmospheric pressure such as aromatic hydrocarbons and acetic acid, the flushing plan often adopts Plan 11/21+Plan 72+75

Typical applications: pumps for light hydrocarbons, aromatics, ethylene oxide, acetic acid, etc. in industries such as petrochemical and coal chemical.
