SANDPIPER® compressed air diaphragm pump HDB

“Heavy Duty Ball” series with ball valve system!

Warren Rupp developed the SB series, tailored to the toughest operating conditions. Not only the extraordinary construction, but also the reliability made this pump the work- and pulling horse within the SANDPIPER product family – of course according to ATEX! Recently revised, this heavy-duty series with ball valve system sets new standards in the usual standard!

The HDB series is used for highly viscous media and liquids which, due to their sedimenting particle load, reach the limits of pumpability – these are the challenges for the “heavy-duty ball”. Extra-weighted valve balls, e.g. for finishing, pickling or paste-like slurries, add extra performance.
