Im looking at this Yamada pump that I can get for cheap. The diaphragn materials are Hytrel. A chemical compatibility chart gives Hytrel a grade of "D" with SH @ 100%. Yet it gives a grade of "A" with SH @ >20%. What is our mix rated at as far as percentage of SH? Can Hytrel be used?
Snatch it !!!!! Do not be afraid of a big pump, your compressor will run it just fine.
Be careful, many big air pumps have ANSI Flange connectors vs threads, make sure it has threaded connections not ANSI Flange, they leak, and are a PITA
