Sandpiper S1FB1ABWANS000 1 Inch Air Double Diaphragm Pump

The Sandpiper S1FB1ABWANS000 is a new 1-inch air-operated double diaphragm pump constructed of ductile iron for industrial fluid transfer applications. The pump is powered by compressed air and features dual diaphragms that reciprocate to move fluid without mechanical seals, making it suitable for abrasive slurries, corrosive liquids, and shear-sensitive applications. Double diaphragm pumps of this size typically deliver flow rates up to 36 GPM at 100 PSI with inlet/outlet ports accepting 1-inch hose or pipe connections. The S1 model designation indicates Sandpiper's standard industrial-duty series; the FB variant denotes ductile iron construction with fluoro elastomer (FKM) seals standard for compatibility with petroleum-based fluids and many aqueous solutions. This pump operates at 80–100 PSI air supply pressure and requires no electrical power, lubrication, or priming, making it ideal for field operations, dewatering, batch transfer, and circulation in manufacturing, mining, and construction settings.
