The series H rotary piston vacuum pump is a sort of vacuum production equipment suitable for pumping ordinary gases and condensable gases(when a gas ballast used). The pump must be fitted with appropriate accessories if gas rich in oxygen explosive corrosive to ferrous metal, chemical reactive with vacuum pump oil. The series H pump can be a backing pump when combined with another high vacuum pump as well as operate singly. It is widely used in vacuum smelting. Vacuum drying, vacuum impregnation and high vacuum simulation testing. Etc.
The pump can't pumps those gases, such as contained oxygen more, exploitable, corroding metal, being chemical reaction with pump oil and the gas contained grained dust. It either can't used for transporting gases.
It widely used for vacuum furnace, vacuum coating, vacuum packing, vacuum metallurgical, vacuum drying, aviation aerospace、high vacuum imitation experiment、solar power energy battery and other vacuum work widely used.
It widely used for Titanium Sponge Magnesium metal.
