LV vacuum pump are usually used to pump gas and water vapor without solid particles, water-insoluble, non-corrosive gas, and the suction pressure can reach 33mbar absolute pressure (97% vacuum). The pump changing the material of pump host, it can also be used to pump corrosive gases or use corrosive liquids as working fluids. LV liquid/water ring pump are widely used in many processes in industrial production. Due to the rapid development of vacuum application technology, the application of water ring pumps is increasing.

First Air Cooled Dry Variable Pitch Screw Vacuum Pump.

DIP pump widely used in experimental facilities, vacuum distillation, reactor, vacuum filtration, vacuum concentration, vacuum drying, besides, also can use for compressed and transfer gas. 

PP pump/compressor widely used in oxygen machine, dental medical equipment, test equipment, vacuum beauty slimming equipment, printing plate printing machine etc. 

DV double stage rotary vane vacuum pump is the basic vacuum equipment of pumping gas from closed container, which take the advantages of compact structure, small size, light-weight, low noise, low vibration etc. It not only independent use, but as the backing pump of the booster pump, diffusion pump, molecular pump. Pumping speed range is 4-90m3/h, the user can adjust as needs.
