Is sulfur erosive on a pump
Is sulfur erosive on a pump
(OP)
I have gasoline with 3661ppmw (0.36%) of sulfur at 38degrees C.
Can somebody advise me if this concentration can actually damage my wear rings/faces.
I've read gasoline can be eventually sold at 500ppm... but more than 7 times this concentration!!! hummm!!!
What kind of measures do I have to take, from the pump constructive point of view.
Thanks

Modern pumps have been redesigned to design around the lack of sulphur lubrication. But early on......
