I. Overview

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.

II. Main Features

  • Small power consumption, remarkable energy saving effect;
  • Small occupied area, low noise;
  • With compulsive water-cooling for cylinder, cooling effect is good;
  • Advanced sealing structure is adopted, eliminating the phenomenon of the oil spilled outward;
  • For reasonable structure and even forced of moving parts, it has long service life.

Working Range: suction pressure is 1013hpa(A)~5hpa(A), discharge pressure is 1013 hpa(A).
If the suction, discharge pressure exceeds the above values, the motor power need to be adjusted, it also can be customized.
