WL, WLW vertical reciprocating oil-free vacuum pump are upgrading product of W horizontal vacuum pump, which is a major equipment to get a rough vacuum. As a result of the whole sealing means, the complete isolation of the crankcase and cylinder is achieved. With the adoption of self-lubricating material for piston ring, the pump realizes the advanced oil-free lubricating function. Since no sewage discharge, this type of pump is particularly applicable for the manufacturing process, such as vacuum distillation, vacuum evaporation, vacuum drying, vacuum concentration, vacuum impregnation, etc, in the field of chemical, pharmaceutical, food and so on.
