Product Introduction
Rotary piston vacuum pump is suitable for air and other ordinary
gases, with a gas ballast valve, witch could be applied to pump
condensable gases (such as vapor). The pump should be equipped with
appropriate accessories if the gas pumped has the following
features, such as rich in oxygen, explosive, corrosive to ferrous
metal and chemical reactive with the vacuum pump oil. This series
of pumps could be operated in single unit or act as the pre-process
pumping unit for the next high vacuum pumps, such as diffusion or
roots pumps. It is widely used in the industries of vacuum coating,
vacuum heat treatment, vacuum impregnation, vacuum smelting, vacuum
metallurgy, vacuum drying, molecular distillation and altitude
simulation testing.
