PS8 2" 51mm AODD models featuring the original air-operated double-diaphragm pump design by Jim Wilden. Clamped metal pumps offer a simple, rugged design for general commercial and industrial applications. Engineered 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 Jim Wilden's 2" PS8 clamped pumps have pumped many billions of gallons of fluid on an yearly basis.
