SAMOA Double Diaphragm Pump – 2 Inch, 650 L/min - UP20A-BAC-MMA

High-Volume SAMOA 2-Inch Diaphragm Pump

High-volume fluid transfer, chemical dosing, and bulk batching require uncompromising mechanical reliability. The SAMOA UP20A-BAC-MMA Pivot Series is an elite air-operated double diaphragm pump engineered specifically for heavy-duty industrial environments. Built in Spain with a rugged aluminum central body and fluid chambers, this 2-inch powerhouse delivers a staggering maximum free flow of 650 L/min (172 gal/min). Its core strength lies in its patented frictionless pivoting air valve, which radically reduces compressed air consumption, minimizes vibration, and ensures smooth, non-stall operation even under low air pressure conditions.

Fully ATEX certified for explosive atmospheres, it guarantees maximum safety in hazardous zones. The pump is equipped internally with Santoprene diaphragms, valve seats, and balls, granting it excellent fatigue resistance and broad chemical compatibility for water-based and general-purpose fluids. It effortlessly passes suspended solids up to 6.4 mm (0.25") without clogging and boasts incredible suction capabilities of 5m dry and 8m wet, making it the ultimate fluid distribution solution for deep sumps, commercial tanks, and large-scale manufacturing facilities.

Key Features & Benefits:

• 1:1 Pressure Ratio: Operates with a direct 1:1 pressure ratio, providing precise and predictable control over fluid discharge simply by adjusting the air inlet pressure.
• Superior Flow: Delivers an immense 650 L/min free flow, making it ideal for high-volume transferring and bulk distribution.
• Versatile Pressure Range: Engineered for consistent performance across a wide operating air pressure spectrum, from 1.5 to 8 bar (20 to 120 psi).
• Pivot Series Technology: Features a patented, frictionless pivoting air valve that eliminates stalling and ice build-up.
• Extreme Durability: Built with a robust aluminum central body, fluid chambers, and manifolds to endure harsh industrial environments.
• Santoprene Components: Internal diaphragms, valve seats, and balls offer extremely high fatigue resistance and excellent chemical compatibility.
• ATEX Certified: Fully groundable and compliant for safe operation in potentially explosive atmospheres (Ex II2 GD IIB/IIC 95 ˚C).
• Solid Handling: The specialized pump design easily passes fluids containing suspended solids up to 6.4 mm without internal damage.
• Deep Suction Lift: Offers impressive 5m dry and 8m wet suction lift, allowing for highly versatile installations in deep tanks.
• Maintenance-Friendly: External bolt configurations (Carbon Steel) and a simplified air motor drastically reduce downtime during servicing.
• Reduced Noise Pollution: Operates at a controlled sound level of 85 dB, ensuring a safer and more comfortable workshop environment.
