1/2" (13mm) Clamped Plastic Pro-Flo (P1)

When Jim Wilden introduced the 13mm (1/2") Pro-Flo® series plastic pump series to his product lineup, he opted for a clamped design—a choice informed by his expertise. These plastic pumps mirror the advantages of their metal counterparts, offering a straightforward and robust construction ideal for chemical applications. Designed with maintenance ease in mind, these 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 reliably moved billions of gallons of fluid annually.
