Introduction:
LG(B) 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.

Advantages:
1.Oil& Water free Dry running operation makes clean vacuum.
2.Can achieve ultimate vacuum as low as 2Pa(50hz), 1Pa(60hz).
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.

Applications:
Chemical & Pharmaceutical Processing,Solvent Recovery, Crystallization, Vapor Coating,Petroleum and semiconductor markets.etc.

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.

3. LG model is same pitch screw pump, LGB is Variable pitch screw pump.

4. This outlet diam is SS304 silencer diameter.
