1 esistance and Material Selection Guide for Drum Pumps The information in the following guide lists the corrosion resistance of four materials used in the drum pump outer tubes. Additional wetted materials maybe found inside the pump tube such as Alloy 625, PTFE, Viton, etc. efer to the series specific flier (PF Series flier for example) for a complete list of wetted components. This information is to be considered as a basis for recommendation, but not as a guarantee. Where chemical compatibility is in question, the material should be tested under actual field conditions to determine the best choice. All test data listed is at ambient temperature (72º Fahrenheit / 22º Celsius) unless otherwise stated. Compatibility = ecommended F = Fair, should be tested under field conditions N = Not recommended - = Unknown, contact chemical supplier * Use only air or explosionproof electric motors with stainless steel tubes and static protection kit when pumping flammable and combustible materials Note: When pumping solvents, the TTS Series is generally the best choice. A = air O = open weatherproof T = TEFC (totally enclosed, fan cooled) X = explosionproof electric to Pump Series Key: = TTC Series Polypropylene = EP, PFP, TBP Series PVDF = PFV Series Stainless Steel = BTS, PFS, TBS, TM, TTS Series
