The 1 1/2" 38mm Wilden® Pro-Flo Shift PS400 bolted plastic air-operated double-diaphragm (AODD) pump series combines maximal performance & efficiency with remarkable containment. Wilden's bolted-construction pumps offer improved flow rates and a redesigned liquid path that reduces internal friction for maximum output and longer diaphragm life.
