SAMOA Double Diaphragm Pump – 3 Inch, 1000 L/min - UP30A-BAC-MMA

High-Volume SAMOA 3" Double Diaphragm Pump

When industrial operations demand extreme fluid transfer capabilities, the SAMOA UP30A-BAC-MMA Pivot Series stands unmatched. This heavy-duty 3-inch air-operated double diaphragm pump is precision-engineered in Spain for large-scale dosing, evacuating, and bulk distribution. Built around a robust aluminum central body, it achieves a colossal maximum free flow of 1000 L/min (264 gal/min). The system is powered by SAMOA’s frictionless pivoting air valve, which radically minimizes compressed air consumption while guaranteeing a smooth, no-stall operation even under the most demanding conditions.

Fully ATEX certified, it ensures absolute safety when operating in potentially explosive atmospheres. Internally, the pump is equipped with high-grade Santoprene diaphragms, valve seats, and balls, granting it incredible chemical compatibility and mechanical fatigue life. Delivering a massive 10 liters per cycle, and capable of passing suspended solids up to 12.7 mm (0.5"), it boasts unparalleled suction lift capabilities, making it the definitive choice for large-scale manufacturing facilities and deep commercial sumps.
