InPower industrial dry vacuum pumps LG series and LGB series screw vacuum pumps adopt,The main and driven rotors of these two series of screw vacuum pumps have the same outer profile, opposite rotation direction, uniform meshing clearance, closed meshing line, good sealing performance, and high pumping efficiency, with a 4.5-level variable lead rotor.
Model：LGB20/30/50/70/110/150/180/220/270/300/330/360/400/450/500
Ultimate vacuum: ≤1Pa
SPEED 50 Hz:65-2000m3/h
Technical parameters:
Characteristic：
This series of screw vacuum pumps has no oil lubrication in the pump chamber and can achieve clean vacuum. Screw vacuum pumps require anti-corrosion treatment when pumping corrosive gases.
Characteristics of variable pitch screw vacuum pump: The rotor structure is more complex, the precision requirement is higher, the rotor processing difficulty is higher, and the processing time is longer; At the same time, the variable lead screw vacuum pump has lower operating power, lower noise, and lower pump operating temperature.
There is no oil in the pump chamber, which is pollution-free and maintenance free for the vacuum system. Maintenance is simple and labor costs are reduced
Dry operation solves problems such as oil pump smoke and oil leakage, ensuring safety and environmental protection.
Applicable environment: corrosive environment, high water vapor environment, high dust environment, flammable and explosive environment, high vacuum environment, etc. Oil free screws are very suitable. Factory 1Pa, high ultimate vacuum degree
