LG/LGV Dry Screw Vacuum Pump

Dry screw vacuum pump is an air extraction device that uses a pair of screws to perform synchronous high-speed reverse rotation in the pump casing to produce air suction and exhaust. The two screws are supported by bearings after fine dynamic balance correction and are installed in the pump casing. There is a certain gap between the screws, so when the pump is working, there is no friction between them, the operation is smooth, the noise is low, and the working chamber does not require lubricating oil. Therefore, the dry screw pump can pump out gases containing a large amount of water vapor and a small amount of dust, has a higher ultimate vacuum, lower power

 consumption, and has the advantages of energy saving and maintenance-free.

Product Features:

• There is no medium in the working chamber, so a clean vacuum can be obtained;

• There is no gap between rotating parts, it can operate at high speed, and the overall volume is small;

• The gas is not compressed in the pump and is suitable for extracting condensable gases;

• Can extract gases containing a large amount of water vapor and a small amount of dust;

• High vacuum degree, the ultimate vacuum degree can reach within 1Pa;

• The screw is made of high-strength special material, which is dense, wear-resistant and has stable performance;

• Rotating parts have no friction and low noise;

• Simple structure and easy maintenance;

• Wider range of use: can be used in corrosive environments;

• There is no fuel consumption and no water dripping during the working process;

• The pumped gas is discharged directly from the pump body, without polluting the water, without environmental pressure, and gas recovery is more convenient;

• It can be combined with Roots pump and molecular pump to form an oil-free unit;
