The 2" 51mm P8 Pro-Flo clamped metal pumps, designed based on Jim Wilden’s original air-operated double-diaphragm (AODD) pump design, feature a straightforward and rugged design suitable for general industrial applications. These pumps prioritize ease of maintenance, allowing simple installation and quick serviceability. With just a single tool, the pump can be disassembled and reassembled. Over time, hundreds of thousands of Jim Wilden’s clamped pumps have successfully moved billions of gallons of fluid annually.
