The Pro-Flo P420 / P430 Wilden® bolted metal pump, also known as FIT, sets the latest standard for pump performance. 1 1/2" / 38mm AODD pumps feature an enhanced flow path design, Wilden's bolted-construction pumps offer improved flow rates (up to 35% over competitive models) as well as improving diaphragm life overall. Wilden bolted diaphragm pumps are also designed for exceptional containment and have the exact bolt down footprint and inlet / outlet discharge connections as Wilden clamped pumps for easy replacement.
