Wilden’s 13mm (1/2") Pro-Flo® series original air-operated double-diaphragm (AODD) pump design, featuring clamped metal pumps, provides a straightforward and robust solution for general industrial applications. These pumps are designed with maintenance ease in mind, allowing simple installation and quick serviceability—requiring only a single tool for disassembly and reassembly. Over time, countless Jim Wilden clamped aluminum and staibless steel pumps have reliably moved billions of gallons of fluid annually.
