Rotary Oil Vane Vacuum Pump Specifications:

How does the Oil Lubricated Rotary Vane Vacuum Pump Work?

  • The electric motor is direct coupled to the rotor which is mounted on oil lubricated bearings eccentric to the circular casing.
  • The vanes (normally 3 vanes are fitted) slide in slots machined in the rotor against the inside of the casing by centrifugal force.
  • As the rotor spins gas flows into the enlarging suction chamber and is enclosed between adjacent blades, the enclosed gas is then compressed until it is exhausted through the outlet valves to atmospheric pressure.
  • The lubricating oil is separated from the air in the discharge chamber, fine coalescing filters are used to purify the exhaust air and recover all of the oil.
  • The recovered oil is recirculated through a filter and air cooler by the vacuum pump suction pressure.
  • This reliable and proven design can operate at very high vacuum levels to 0.5 mbar Absolute Pressure which is equivalent to 101 kPa Vacuum

Additional Features of the Rotary Vane Vacuum Pumps

  • Highest Quality Materials and workmanship
  • High Quality Composite Vanes for long life and reliability
  • Suction Non Return Valve as Standard prevents reverse rotation on shut down
  • Standard with Gas Ballast to enable trouble free pumping of water vapour
  • Wide range of accessory equipment available to adapt to specific applications including, suction filtration, suction separation vessels for liquids and solids, suction cups, oil level and temperature switches.
