BOLA Magnetic stirrer couplings – what you should know about.
The magnetic stirrer couplings P-MRK are optimal for the use of PTFE-covered stirrer shafts from BOLA with a shaft diameter of 8 to 10 mm. The power is transmitted from the stirrer drive via the drive magnet to the rotor magnet connected to the stirrer shaft. This makes the magnetic stirrer coupling a self-contained, gas-tight system that is perfectly suited for applications under vacuum. Depending on the design, the reactor cover is sealed either by a ground joint core (NS 29/32 or NS 45/40) or as a flat flange (DN40 or DN50), so that gases produced during the mixing process cannot escape.
An efficient power transmission up to 90 ncm and rotation speeds up to 1.500 rotations per minute are ideal for the most varied applications in the lab or production. BOLA magnetic stirrer couplings P-MRK do not need any lubricants and are specially made for permanent use. Due to the guide in a stirrer shaft holder, which is connected to the drive magnet, there is no abrasion on the guide or the stirrer shaft that could contaminate the medium. For cleaning all components can be disassembled and, if necessary, be exchanged.
