The 2" 51mm Wilden® Pro-Flo Shift bolted metal pump, also known as FIT, sets the new standard for pump performance. PS820 / PS830 AODD models feature an enhanced flow path design, Wilden's bolted-construction pumps offer improved flow rates (up to 35% over competitive models) as well as improved overall diaphragm lifespan. 51mm Wilden bolted pumps are also designed for exceptional containment and have the exact bolt down footprint and inlet and ourlet discharge connections as Wilden clamped pumps for easy replacement.
