P820 and P830 are the same bolted pump with threaded or flanged ports, so choose by your pipework. The PS8 is the odd one out: a clamped SHIFT pump that moves more liquid and is noticeably lighter, but it is a different pump, not a drop-in replacement for either.
All three run on up to 125 psi (8.6 bar) of air. The builds we checked are rated 32 to 175 °F (0 to 79 °C), and the FIT pumps handle solids up to 0.25 inch (6.3 mm). Example builds: 08-15508 (P820, Buna-N), 08-15538 (P830, Buna-N) and 08-16188 (PS8, Buna-N).
