Roots Vacuum Pump

Roots Vacuum Pump

Roots vacuum pump (also called mechanical vacuum booster), As the main pumping equipment to obtain medium and high vacuum, is a positive-displacement vacuum pump and an oil-free dry vacuum pump.

Five point bearing/machine seal designs, multiple supports and seals for high reliability.
Double oil tank design for improved stability.
Synchronous gears of helical gear design at the drive end to improve silence, stability and reliability.
Nitrogen gas barrier to block gas from entering the oil tank, prolongservice life.
Internal coating protection against corrosion, especially suitable for pumping out condensable,flammable, explosive and toxic gases.
Large differential pressure up to 120 mbar.
Optional cooling methods: air cooling, water cooling.
Optional nickel plating or PFA/PTFE coating of fluid contact
O-ring in the mechanical seal, optionalfluororubber or perfluoroether rubber.
High pumping speeddesign, up to 110,000m3/h inlet flow rate.
Optional outer seal is mechanicalseal and inner seal is oil slinger ring seal, also optional five mechanical seals plus labyrinth seal.
