1.How a dry vacuum pump works:

Sihi dry-type screw vacuum pump, is the use of a pair of screws, in the pump shell for synchronous high-speed reverse rotation generated by the suction and exhaust gas pumping equipment, two screw fine dynamic balance correction, supported by bearings, installed in the pump shell, there is a certain gap between the screw and the screw, so when the pump works, no friction between each other, smooth operation, low noise, working chamber without lubricating oil, therefore, Sihi dry screw pump can remove a large number of steam and a small amount of dust in the gas occasions, the utility model has the advantages of higher limit vacuum, lower power consumption, energy saving, maintenance-free, etc. . It is the oil seal type/water ring type/jet type vacuum pump replacement products.

2.Revolutionary Features of the SIHIDRY VACUUM PUMP:

Sihi dry pump is a real dry pump; no gear drive, no lubrication, so it is a completely oil-free, non-process pollution dry vacuum pump; no liquid waste generated, will not generate any liquid waste treatment costs.
