This series of electric oil drum pumps are portable tubular axial flow pumps, widely used in the chemical, petrochemical, fine chemical, dye chemical, water treatment, pharmaceutical, food and other sectors for pumping various liquids. The oil pump can be directly inserted into the material drum (applicable to steel drums that comply with the GB/325-1991 standard) to draw the liquid in the drum. It can convey various oils, corrosive chemical solutions and other liquids. According to the nature of the liquid being conveyed, the wet parts of the electric oil drum pump body can be made of aluminum alloy, stainless steel, 316 stainless steel, etc. The drive motor is equipped with a variety of options such as single-phase standard motors, explosion-proof motors, and high-speed motors. According to the material and motor, the models can be classified as: SB-1, SB-2,SB-3,SB-3-1,SB-4,SB-5,SB-6,SB-7, SB-8 series aluminum alloy, stainless steel or explosion-proof type. This series of pumps can be selected according to explosion-proof areas and non-explosion-proof areas. For use in explosion-proof areas, explosion-proof motors should be configured. These motors are divided into three types of unit models. When the usage conditions involve various flammable and explosive mixtures, group models should be selected.
