11 Planning guide Resistance list for pumps of the Wilo-Multivert MVI/MVIE 2.. series to 16-6 and Wilo-Economy MHI/MHIE - series 2.. to 16.. This list makes no claim to completeness. The specifications concerning the application possibilities of various pumping materials for the conveyance of the fluids listed have been compiled to the best of our knowledge. They should however not be regarded as any more than non-binding guidelines. No guarantee claims whatsoever are to be derived therefrom. It is only very rarely in everyday practice that the fluids listed here are conveyed as pure substances. Even miniscule admixtures of other substances could decisively influence or alter the chemical-aggressive behaviour of a basic substance. Incrustations, condensate formation and temperature increases also generally have disadvantageous effects. In many cases, practical experience is required before a conclusion can be reached as to whether or not the suitability of a particular material is sufficient. Caution: When combined with water, Viton is resistant only up to a maximum temperature of 9 C We request that the key code and/or the remarks be taken into account when using the resistance list. In the event of questions concerning the resistances of the Wilo- Multivert MVI/MVIE Series 16../32../52.. please contact the Sales and Services office responsible for your region. Remarks: Furthermore, the qualities of the fluid, such as density, solidification points, viscosity, etc. and/or explosion-protection ( Ex-protection ) regulations are to be taken into account additionally and separately in conjunction with this resistance list. The application limits of the pumps in terms of pressure and temperature are to be taken into account. Resistance list Vol.-% max. Temp.
