Note:

The above specifications are for maximum working pressure of 100 bar / kg/cm² & 250ºC temp. & autoclaves machined from bar stock. The same shall change for higher pressure/ temperature / fabricated/ special autoclaves.

Overall dimensions are indicative, they may change depending on the optional accessories or specific design modifications opted.

Panel size is 300 x 300 x 300mm (For standard 1φ with temp, RPM and Pressure) and 535W x 400D x 355H mm (for standard 3φ with temp, RPM and Pressure)


» Construction and Working Principle
It is a zero leakage maintenance free coupling directly driven by the motor. It consists of external magnet rotor, which is driven by the motor. A stationary shell is threaded / bolted to reactor head & completely isolates the external rotor from the inner rotor. As the external rotor rotates, the internal also rotates in synchronism. The reactor's shaft is threaded to the inner rotor. High energy permanent (rare earth) magnets are fixed inside the inner & outer rotors. A water cooling jacket protects the magnets & other components from excessive temperature arising from the reactor.
