Active Magnetic Bearings and Dry Gas Seals

Elimination of parasitic horsepower losses and oil shear, which may consume up to 2% of the unit s output power. 

Elimination of mechanical wear, which essentially provides unlimited bearing life. 

Continuous monitoring of unit operation providing information on rotor location, balance, speed, and bearing loads, which were previously difficult and costly to obtain. 

These benefits directly translate into lower costs and improved operating efficiency for rotating machinery. Lubrication is unnecessary. The bearing is operable in hostile environments and, in many cases, can operate in the process fluid at high pressures and temperatures. Experience shows that total consumption of frictional power is drastically reduced. 

Backup features can be incorporated to provide additional operation security. Emergency run-down bearings (Eigure 6-2) prevent damage in die case of unforeseen power interruptions or electronic failures.
