SAMOA Industrial presents the UP15 Non-Metallic 1 1/2" Air-Operated Double Diaphragm Pump, part of the innovative PIVOT Series. Designed to deliver superior performance, energy efficiency, and long-term reliability, the UP15 sets new standards in non-metallic diaphragm pump technology.
The UP15 is engineered to handle demanding fluid transfer applications while maintaining stable and efficient operation. Its reinforced polypropylene and PVDF construction options ensure excellent chemical compatibility and durability under abrasive and aggressive conditions.
At the core of the UP15 is SAMOA’s advanced air motor technology, featuring:
- Frictionless air distribution system
- Reduced air consumption
- Ice-free exhaust design
- No dynamic seals, eliminating wear components
- Smooth Start Shifter (3S) for reliable low-pressure start-up and anti-stall operation
The innovative Pivot-Shaft air valve ensures smooth operation and fast valve changeover, minimizing vibration and flow pulsation. In addition, the bolted multi-port construction withstands up to four times the pressure of clamped pumps, guaranteeing superior sealing reliability even under dead-head conditions.
Available in multiple material configurations and compatible with main competitive brands, the UP15 allows easy replacement and integration into existing installations.
