When Wilden introduced the 6mm (1/4") Pro-Flo® series plastic pumps 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 Jim Wilden clamped plastic pumps have reliably moved billions of gallons of fluid annually
