When the first 1 1/2", 38mm clamped plastic Pro-Flo Shift pump series was added to the Wilden product portfolio, he designed it with what he knew best: a clamped pump. Incorporating the same benefits as a clamped metal pump, these plastic versions offer a simple, rugged design that is ideally suited for chemical applications. Engineered with ease of maintenance in mind, clamped plastic 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 clamped plastic pumps have pumped billions of gallons of fluid on an annual basis.
