Table 2 Chemical resistance of some selected mediums
Please note that this table is for indication only and needs to be verified with the actual
medium in the process.
3.2
Solids and suspensions
Solid particles should not have a diameter greater than 0.1mm, as larger solids can prevent valves from
proper sealing. This however depends also on the solid concentration and low concentration of larger
particles might be acceptable. Even though the pump is not damaged by particulates, care should be taken
when pumping abrasive solids. In this case please consult the factory for further support.
3.3
Sticky Mediums
In case sticky mediums are pumped, please make sure that the pump is flushed and cleaned thoroughly
immediately after the process to prevent sticking of valves.
