The Chemical Compatibility Guide is to be used to help select the most satisfactory combination of materials, however it is only a guide. Service conditions may vary and can affect accuracy of compatibility. Consult the chemical manufacturer for best compatibility.
Avoid Serious Injury: Always use caution, shields, and/or personal protection when working with or handling chemicals or product containing chemicals.
Chemical Compatibility Ratings
A = Excellent
B = Good
N/R = Not Recommended
NO DATA = Limited/Conflicting Data
Notes:
(1) Max rated temp is 140 °F due to temperature rating of the diaphragm.
(2) PVC liquid ends have a max rated temperature of 104 °F.
(3) Compatibility ratings are given at ambient (70 °F) temperatures.
(4) The diaphragm for the IX-B is a solid PTFE/PFA diaphragm.
(5) For LKN sizes 45-57, valve seats are the same material as the pump head.
(6) For the LKN the PVC liquid ends are black.
