Chemical resistance
The table below shows the standard product wetted materials for multiple-use and single-use Quattroflow
pump chambers. The second table shows an overview of the chemical resistance against some mediums
which are often used with Quattroflow Pumps.
For multiple-use pump chambers made of stainless steel standard stainless steel is 1.4435 (316L). Generally
this material has got good characteristics to resist corrosion. Certainly there is a risk of pitting and surface
corrosion when the medium comes in contact with chloride-containing mediums like NaCl. On request we
could offer other stainless steel alloys with higher corrosion resistance. In this case please contact the
Quattroflow Team to get more information and support.
The chemical resistance depends on some factors like mixture, concentration, temperature and standing
time. In case that the chemical resistance is unknown we recommend to test our materials with your medium
under real conditions. Please consult the factory for support.
Please check the chemical resistance of the product wetted materials against our mediums.
If you are not sure about the chemical resistance please contact the Quattroflow Support
Team.
