Stirrer design

FLUKO GM stirrers are designed for slower speed applications where generally a single stirring speed is required. The stirrer shaft is mounted directly onto the gear motor shaft. The stirrer is usually supplied with a standard IEC flange for mounting directly onto the vessel or a stirrer stand. Stirrers with longer shafts are supplied with a seperate shaft mounting.


Genrally a helical geared motor with an application-specific mounting. 3-phase standard motors in either IP 55 or explosion protected, also in ATEX standard. Speed depending on the gear type and the application; up to 900 r.p.m.

Stirrer shafts

The stirrer shafts are solid, and configured for continuous operation. Flange or rapid change connections are available. Every shaft is checked for true running in the factory. The shaft are dimensioned so as to have a large difference between thier operating speed and the resonance frequency.

Stirring devices

The following stirring devices are available: 3 blade propeller, plate agitators, diagonal flat blade agitators, anchor paddles and trapezoidal turbines; all with threaded hole hubs or clamp hubs.


The stirrer shaft and stirring devices are made of high alloy stainless steel SS316Ti (1.4571) or alternatively nonalloyed steel with PE, hard rubber or PVDF coating.
