LG series screw vacuum pump

Summary:

　　LG series screw vacuum pump (also known as twin screw vacuum pump, no oil dry screw vacuum pump) is my company according to the market demand, independent research and development of advanced technology of dry vacuum pump. Because screw vacuum pump without oil lubrication or water seal, pump chamber completely without oil, so screw vacuum pump in the semiconductor, electronics industry requirements without oil clean vacuum occasions and pharmaceutical and chemical solvent recovery process and has incomparable advantage, can be widely used to replace rotary vane vacuum pumps, rotary piston vacuum pump, water ring vacuum pump, water jet vacuum pump, reciprocating vacuum pump, roots water ring vacuum unit.

　　Our production of screw vacuum pump with a unique type of line design and sealing structure, the product has been the national patent certificate, patent No.: ZL 200820225961.2

　　Screw vacuum pump of a guide process is equivalent to the level of pump, a plurality of guide screw vacuum pump the equivalent of multistage pump series, relative to the claw type vacuum pump, multi-stage Roots vacuum pump and multistage tandem dry vacuum pump, because no internal channel between the screw vacuum pump pump at all levels, but directly to the gas from the suction side push to send to the exhaust side, so in the pumping condensable gas, dust and particles in the gas with uneasy blockage and convenient cleaning.
For low (high vacuum) in continuous operation, in front of the screw vacuum pump Roots series vacuum pump, so it can greatly improve the low pressure pumping speed and reduce power consumption. Parameters in detail please reference JZJLG Roots series dry screw vacuum pump unit.
