PMRK compressed air magnetic stirrer drives with M30 thread up to 200/700 bar
PMRK series drives feature a permanent magnetic coupling and a flanged, compressed air-driven motor. The use of a cardan coupling is unnecessary, meaning both vibrations and the installation height are reduced.
This version with M30x2 screw thread is suitable for applications under pressure up to 700 bar, depending on the material, and can easily be screwed into an autoclave lid. Sealing to the autoclave lid is achieved using a cutting ring (HC 22)*, see accessories.
The speed is regulated by a continuously adjustable fine control valve, with an analogue tachometer fitted as standard..
Magnetic stirrer drives are also available in titanium, zirconium and other materials or offering alternative torque levels.
The stirring system is supplied certified to ATEX regulations. Please order desired documentation separately.
