DG type horizontal multi-stage boiler feed pump adopts the hydraulic model of high-efficiency and energy-saving products recommended by the state. It has the advantages of high efficiency, wide performance range, safe and stable operation, low noise, long life, convenient installation and maintenance, etc. It is suitable for medium and low pressure boiler feed water, high-lift water delivery in factories and cities. For conveying clean water or liquids with physical and chemical properties similar to clean water, the temperature of the conveying medium is -20℃～105℃, and the inlet pressure of the pump shall not exceed 0.59MPa (6kgf/cm2). The inlet and outlet of the pump are both vertically upwards, and the shaft seals include mechanical seals and packing seals. When the pump is sealed with packing, the position of the packing ring should be correct, the tightness of the packing must be appropriate, and it is advisable that the liquid can seep drop by drop. The rolling bearing is lubricated with grease, the sliding bearing is lubricated with thin oil, and the oil ring is used for self-lubrication, and the circulating water is used for cooling.
