3. Remove the PTFE bearing from the axle. After this disassembly you should have the
following five parts: shaft tube, axle, rotor, stator and PTFE bearing.
To assemble the dispersing tool please follow above 3 steps in reverse
order (3./2./1.)
When assembling the dispersing tool, always make sure that the PTFE
bearing is fixed correctly and cooled by the working medium.
Otherwise, it may cause serious defects to the whole dispersing tool. Examine the
PTFE bearings regularly. Treat the dispersing tools carefully as they are the hearts of
your dispersing unit. In
particular the axle reacts very sensitive to impacts.
Cleaning
• Immediately after finishing work with the apparatus, the dispersing element must be
cleaned so that substance residues do not stick to the threads.
• Small bacterial cultures can form in the small grooves, and this will create difficulties.
For this reason, and to clean the dispersing tool effectively, it should be run in a solvent
that dissolves the residue, but does not harm the Teflon bearing and the steel.
• For proper cleaning, the dispersing element must be disassembled.
• Proper care and cleaning of the equipment will ensure a longer and better use of the
equipment.
Sterilization
• Chemical processes: Germicidal solutions (formalin, phenol, alcohol etc) can disinfect
in most cases. However, residues must subsequently be removed with sterilized water.
• Sterilizing by humid heat: This means sterilizing with steam at a pressure bar of 2
above atmospheric and a temperature of 120°C
• Sterilizing by hot air: Hot air sterilization is normally carried out at 160°C or 190°C
Corrosion
• Stainless steel is not corrosion proof. Certain chemicals can seriously attack this
material.
• All corrosive agents should only be in contact with the fine steel for a short period of
time. Make sure they do not dry out the material.
• Ensure that the dispersing element is always cleaned properly after every use.
Neutralize lye with solutions and acids.
• Protect all parts from aggressive agents.
