The three phase standard motors are available in all common voltages and 50 or 60 Hz. Standard motors are in protection class IP55. Explosion proof motors according to ATEX standards are available on request. The drive bearings are permanently lubricated and require no maintenance.

Other shaft materials of coatings can be ordered according to the application. Flanged- or quick-change-couplings can also be delivered on request. Each mixer shaft is tested and protocolled for true running in our works. Stirrer speeds are dimensioned with sufficient distance from the shaft's criticle speed.
Stirrers are fitted with interchangeable threeblade propellers, fixed to the shaft either directly threaded or with a hub and grub screws. Other devices such as dispersing discs, flatblade propellers or turbine-propellers can be quoted and dimensioned according to the application. For pass-through operation of the mixer occuring when filling and emptying of the vessel, propellers can be fitted with stabilising rings.
