Material and Fluid Compatibility Check List for Process Pumps
- The data below is prepared based on data provided by the material manufacturers.
- SMC assumes no responsibility for the accuracy of the data or for any damages arising from the
data.
- The material and fluid compatibility check list provides reference values as a guide only; therefore
SMC does not guarantee the application to our product.
Caution
1. Select the wetted parts materials according to the transfer liquid you use to determine the model.
- For the fluid contact area (polypropylene), water, acids, and alkalis are suitable.
- For the diaphragm material, PTFE is suitable for non-permeating liquids.
- Use fluids that will not corrode the wetted parts materials.
2. These products are not suitable for medical or food use.
3. The applicability may vary depending on additives. Take note also of additives.
4. The applicability may vary depending on impurities. Take note also of impurities.
5. Examples of transfer liquids are shown below. Since the applicability may vary depending on your
operating conditions, be sure to check it by means of experimentation.
6. Compatibility is indicated for fluid temperatures specified for the respective products (60°C or
less).
7. These may be penetrated by fluids, and the penetrating fluids may affect parts of other materials.
Note 1) Static electricity may be generated. Take measures to prevent static electricity.
Note 2) Strong acidic chemicals, strong basic chemicals, and hydrofluoric acid are not allowed.
Note 3) The air operated types can also be used for highly penetrating liquids. However, they cannot be used if
the penetrating components damage parts such as seals in the air circuit. In addition, since the exhaust
air contains the gas components penetrating through the diaphragm, take measures to prevent the
exhaust air from going to the solenoid valve.
