This looks like a vacuum pum of a milk machine

[@baymechanic1009]

maybe it was??? It makes positive pressure not negative. it seems like that's how it was designed. not sure how you could pull vacuum off it with the open piston ports. have you ever seen anything made by this company?

[@MagnetbergOfficial]

@@baymechanic1009 No but you can easy turn Pressure into vacuum via a valve. And it pulsates like a milk pump.

@@MagnetbergOfficial Nope. But feel free to prove me wrong on how that would work on this particular pump design.
