The Wilden 51 mm (2") Pro-Flo® SHIFT Series Bolted Metal AODD Pump is a high-performance air-operated double-diaphragm (AODD) pump designed to set a new standard in efficiency, reliability, and ease of maintenance. Featuring a bolted construction, this pump delivers superior flow rates—up to 35% higher than competing models—thanks to an optimized flow path design. It offers enhanced diaphragm life, minimizing downtime and operating costs. With a bolt-down footprint and identical inlet/discharge connections to Wilden’s clamped counterparts, installation and replacement are seamless. Engineered for enhanced containment and durability, it is ideal for demanding industrial applications.
