When Jim Wilden introduced a plastic pump series to his product lineup, he leveraged his expertise in clamped pumps. These 2" 51mm P8 Pro-Flo plastic versions share the same advantages as their metal counterparts, featuring a straightforward and rugged design that suits chemical applications. Engineered for easy maintenance, clamped plastic pumps are simple to install and can be disassembled and reassembled using just one tool. Over time, countless Wilden clamped plastic pumps have successfully moved billions of gallons of fluid annually.
