LG series screw vacuum pump its core technology is a pair of precision machining spiral rotor, in the pump shell for synchronous high-speed reverse rotation of the suction and exhaust effect of the pumping equipment, it is an oil-sealed vacuum pump replacement products, can be pumped containing a lot of water steam and a small amount of dust gas occasions, It is widely used in domestic pharmaceutical, chemical, semiconductor and other enterprises with high requirements for clean vacuum.

LG series screw vacuum pump has a high vacuum degree, can be used alone or as a front pump and Roots vacuum pump to form a medium and high vacuum system.

▌ High process cleanliness

There is no medium in the pump cavity, and a clean vacuum environment can be obtained.

▌ High limit vacuum

Single pump can be pumped from atmospheric pressure to the limit pressure of 1pa below, high pumping efficiency, can greatly simplify the vacuum system.

Strong discharge capacity and convenient cleaning

The spiral rotor has a good conveying function, and solid dust and condensate are not easy to deposit in the pump chamber. When cleaning, open the pump suction port and add an appropriate amount of water or detergent to clean the pump without disassembling the whole pump.

▌ Wide range of applications

Pump cavity and screw rotor surface with special anti-corrosion coating, suitable for the process containing a lot of water vapor and complex media, and high vacuum requirements of the application; The gas is not compressed in the pump chamber, and the working temperature of the pump chamber is above 100℃, which is suitable for extracting condensable gas.

▌ Energy conservation and Environmental Protection

Stable pumping rate, low vibration, low noise, no waste oil, waste water discharge.
