negative pressure dischage pump

Negative pressure discharge pumps are widely used in vacuum distillation, molecular distillation, short-path distillation processes in flash evaporation industries such as petroleum, chemical industry, biodiesel, base oil purification and other flash evaporation industries to extract materials under high temperature and high vacuum from vacuum tower kettles, and have the function of vacuum discharge It has the characteristics of strong capacity, stable flow without pulsation, good wear resistance and long service life. This pump can also be used to support oil filter equipment and does not produce acetylene gas, making it a trusted choice in the flash evaporation industry.
