"Green brand (Lv Pai)" explosion-proof chemical submersible pump, based on the principle of positive-pressure push, is typically designed to solve the problem of vapor blockage in the underground tank of volatile chemicals. The motor and pump are integrated in one body which works below the liquid surface. The medium transported circulates the pump body getting low-temperature rise. The other advantages of this type of pump are listed as follows:  low wear, low vibration, low noise, low energy consumption, large flow, high lift, maintenance-free, high efficiency, and long service life. The pumps achieve Ga-level protection and can be employed in the zone "0", meeting the international standard requirements of EPL (Equipment Protection Level) on flammable and explosive occasions.
