1" (25mm) Bolted Metal Pro-Flo SHIFT (PS220/PS230)

The Wilden® FIT bolted metal pump, 25mm (1") Pro-Flo® SHIFT establishes a fresh benchmark for pump performance. With an enhanced flow path design, these bolted-construction pumps deliver improved flow rates (up to 35% higher than competitive models) and extended diaphragm life. Additionally, Wilden’s bolted pumps are designed for superior containment and share the same bolt-down footprint and inlet/discharge connections as Wilden clamped pumps, ensuring easy replacement.
