Wilden Pro-Flo SHIFT XPS4 Air-Operated Double Diaphragm Pump, 38 mm (1-1/2") 316 Stainless Steel, ATEX Rated, with Muffler and Manual

The Wilden XPS4 is an air-operated double diaphragm (AODD) pump. Compressed air moves two flexible diaphragms back and forth, which draws liquid in and pushes it out. It handles chemicals, solvents, slurries and viscous fluids, and it can run dry without damage.
