FRU Series (180~5800m3/h)

roots booster pump

Design Operation Principle

Based on the simple technology, they are made of a couple of Two-lobe rotating in opposite directions in a stator. Due to the lobe shape of the rotors and to the synchronization of their rotation through a pair of gears, these rotors remain permanently tangent to each other and tangent to the stator. FRU series is suited to a wide range of vacuum applications combined with primary vane pumps, piston pump or dry pumps.

Design Features

  1. Saved energy consumption by reduced operating time by inhaling from ambient pressure.
  2. Steady and excellent performance and applicable in all vacuum applications.
  3. Air-cooling system
  4. The pump have two outlet port, vertical and horizontal, to enable convenient piping with backing pump
  5. ISO flange is used for inlet and outlet port
  6. Low vibration level, low noise level
  7. Easy maintenance and repairing
