Tri-lobe Gas-cooled Roots Vacuum Pump

Product Features:

• When used alone, the ultimate vacuum level directly discharged to atmosphere can reach 150 mbar.
• Multi-stage cascade operation or connection with other backing pumps can achieve medium vacuum ranges.
• A special patented structure ensures the pump will not overheat or overload even when operating at high differential pressures and high compression ratios.
• The three-lobe involute line structure and high-precision machining ensure smooth and quiet operation.
• The advanced balanced mechanical seal provides more reliable sealing performance than traditional frame seals.
• The pump chamber has an oil-free groove, suitable for pumping general air and various special gases.
