How to handle stainless steel and other materials
Stainless steel corrosion
Corrosion such as rust might be caused by chemical attack. Use only cleaning liquids which are suitable
for use with stainless steel. Take care when deciding on the concentration, temperature and exposure
time of the chemicals, to avoid chemical attack.
Non-galling material
This non-galling alloy is a nickel based, corrosion resistant material which was developed for use in
positive displacement pumps. It is listed in the 3-A Standards and is thereby accepted for use with
product exposed surfaces. Do not use in combination with highly concentrated nitric acid, for example,
during passivation of new stainless steel piping systems. In this case remove the rotor and the gate
during the passivation process to avoid damage or chemical attack. When removing the rotor, a double
mechanical seal or a quench with a lip seal is needed, and you should close the connections for the
flushing fluid with plugs to keep the liquid in the pump during the passivation process. Do not use a
concentration of more than 3% of nitric acid for the CIP cleaning fluid.
Handling of elastomers and plastic parts after the passivation process
Check elastomeric and plastic parts after passivation for chemical attack and replace them if necessary.
