Compressed air magnetic stirrer drives with flange

Permanent magnetic coupling and a flanged

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. The flange version is suitable for applications under vacuum and pressure up to 10 bar. The advantage of a flange connection is that forces are distributed over a larger contact surface, allowing the use of higher torques and larger container volumes.

The speed is regulated by a continuously adjustable fine control valve, with an analogue tachometer fitted as standard.
Ball bearings ensure rapid, easy replacement to facilitate maintenance and cleaning.
