Reciprocating vacuum pump is applicable to vacuum impregnation, molten steel vacuum treatment, vacuum distillation, vacuum evaporation, vacuum concentration, vacuum crystallization, vacuum drying, vacuum filtration and vacuum operation of concrete in petroleum, chemical industry, medicine, food, light industry, metallurgy, electrical and other industries; It is not suitable for pumping out gases with high oxygen content, explosive, corrosive to metals and containing particulate dust, nor for transporting gases from one container to another as a transfer pump.
Model WLW oil-free (corrosion-resistant) vertical reciprocating vacuum pump is an updated product of W-type horizontal vacuum pump and the main equipment to obtain coarse vacuum. Due to the full sealing device, the complete isolation of crankcase and cylinder is realized; In addition, the piston ring uses self-lubricating materials to realize advanced oil-free lubrication. Since there is no sewage discharge, this type of vacuum pump is especially suitable for vacuum distillation, vacuum evaporation, vacuum drying, vacuum concentration, vacuum impregnation and other processes in chemical, pharmaceutical and food industries.
