    1 Person needs an answerI have this question too


    Hello Warren,
    This pump only has a seal designed for clear liquids or non abrasives, that being said the standard seal is Carbon/Ceramic/Viton. This seal is soft and will not stand up to abrasives, inorder to go with a better seal you would need to go to a Silicon Carbide / Ceramic which is not an optional seal for this pump. The way to get a better seal is to remove it get a dimention on it ( we dont have any dimentions on seals for this pump) cross it to a Pac-seal or US seal..
    I hope this answers your question, thanks for using Grainger Ask & Answer!
