Featuring the original 25mm (1") Pro-Flo® Series air-operated double-diaphragm pump design by Jim Wilden, clamped metal pumps offer a simple, rugged design for general industrial applications. Designed with ease of maintenance in mind, clamped pumps are simple to install and are made for quick serviceability, allowing the pump to be taken apart and put back together with only a single tool. Proven by the test of time, hundreds of thousands of Wilden clamped pumps have pumped billions of gallons of fluid on an year in and year out.
