Magnetic stirrer couplings with ground joint Manufacturer,Supplier and Exporter in India
Product Code : TVT-CELE-10736
Magnetic Stirrer Couplings with Ground Joint use a permanent magnetic coupling to drive a stirrer shaft through a sealed ground-glass joint, allowing reliable mixing inside a vessel operating under vacuum without any physical shaft penetration of the seal.
How It Works
A magnetic coupling transmits rotational drive from the external motor through the vessel wall to the internal stirrer shaft without a direct mechanical connection, which is what allows the assembly to maintain vacuum integrity at the ground joint. The drive shaft is supplied with a 6 mm external square stub for connection to a compatible overhead stirrer or motor, and an FKM seal combined with a stainless-steel ball bearing supports smooth, reliable rotation at the rated speed.
