Description: LG Series screw vacuum pump is "NO OIL NO WATER" in contact with the process vapors,so they also called dry screw vacuum pump.
Product info
LG series dry screw vacuum pumps can manage both condensable vapors and some solids with no residue. They offer a number of advantages over the traditional vacuum pump designs. There's is "NO OIL NO WATER" in contact with the process vapors, so therefore they are considered environmentally friendly.
Applications :
Chemical & Pharmaceutical Processing,Solvent Recovery, Crystallization, Vapor Coating,Petroleum and semiconductor markets.etc.
Characteristic :
1. Oil& Water free Dry running operation makes clean vacuum.
2. Can achieve ultimate vacuum as low as 0.6Pa
3.Quiet operation; Equipped with special silencer,lower noise.
4.No metal-metal contact between Screw and Casing ensures long pump life.
5.Simple design results easy maintenance.

Remark:
1) The oil consumption on above sheet is for reference only. The machine can always adopt fluoride or mineral substance oil. Pump oil and lubricant oil will be matched before delivery.
2) Above cooling water consumption data is tested with ambient temperature at 30℃, cooling water suction temperature at 20℃,and water pressure from 0.15MPa to 0.2MPa. Various working condition will cause different cooling water consumption.
