Drive Assembly with Mechanical Seal

Drive Assembly with Mechanical Seal

The Drive Assembly with Mechanical Seal is designed for leak-proof agitation in glass reactors and process vessels operating under higher pressure, vacuum, or continuous duty conditions. Unlike flexible bellow seals, the mechanical seal provides a positive dynamic seal, making it suitable for demanding chemical processes.

This assembly is widely used where process integrity, zero leakage, and long operational life are critical.

The assembly integrates a precision mechanical seal with a stirrer drive shaft, ensuring reliable sealing between the rotating shaft and the stationary reactor flange. The seal faces remain in constant contact, preventing vapour escape, liquid leakage, and air ingress during agitation.

The design supports stable operation under pressure, vacuum, and temperature variations, making it ideal for industrial glass reactor systems.
