Im not sure what youre getting at? Ball Checks? Swing Checks? Ball is maybe air/water, swing, water.. These pumps use manifolded commercially available vacuum components for the multi-stage. What does it matter what type of check they use? Are you trying to cobble together your own on the cheap? If so you just have to figure it out... They are not cheap by any means and thats for a reason.
