Mixing Technology

Compact stirrer SM
For tasks involving the stirring of aqueous products in small drums,
we recommend a fast-running stirrer of type SM.

Construction
The stirring shaft is fitted directly to the drive with a hub coupling. The stirrer can
be mounted onto a container using the motor's IEC flange. Alternatively
the stirrercan be mounted using a clamp on the motor foot, suitable for mounting
on traverses or stirrer stands; available on request.

Drives
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. Motor speeds: 3000, 1500, 1000 and
750 rpm (at 50 Hz) are available in all stirrer sizes. Pole changeable motors available. ns.

Mixer shafts
The mixer shafts are dimensioned for continuous operation. The standard shaft is made
of highly corrosion resistant SS 316 Ti. 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.

Stirring devices
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.

Materials
The mixer shafts and mixer elements are all made of stainless steel (316Ti)
or unalloyed steel with PE-, hard rubber or PVDF-coating. Motor casing are painted
silver with 2 component paint. Other RAL colours on request.

Stirrer mounting and shaft seals
The standard version of the FLUKO High Speed Mixer Typ SM is constructed for operation in
open or closed non pressurised vessels. The mounting is made directly onto a counter
flange. On request a motor flange/foot construction can be supplied. Various seals are available for the
stirrer. From simple lip seals integrated into the mounting flange to mechanicalseals or
stuffing boxes mounted in special seal housíngs with or without pressurised quench systems. For mixer
shaft-lengths over 1800 mm an additional shaft bearing in a special bearing-housing is available.
