FRU720 {600m3/h)-50HZ, 720m3/h-60HZ}
Design Features
- Saved energy consumption by reduced operating time by inhaling from ambient pressure.
- Steady and excellent performance and applicable in all vacuum applications.
- Air-cooling system
- The pump have two outlet port, vertical and horizontal, to enable convenient piping with backing pump
- ISO flange is used for inlet and outlet port
- Low vibration level, low noise level
- Easy maintenance and repairing
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.
