2" (51mm) Bolted Metal Pro-Flo (P820/P830)

Wilden 51mm 2" Pro-Flo Series FIT bolted metal diaphragm pumps establish a new benchmark for pump performance. Here are its key features:

1. Enhanced Flow Path Design: The FIT pump incorporates an optimized flow path design, resulting in improved flow rates. Compared to competitive models, it can achieve flow rates up to 35% higher.

2. Extended Diaphragm Life: The FIT pump’s construction enhances diaphragm longevity, ensuring reliable and efficient operation over time.

3. Superior Containment: Designed for superior containment, the FIT pump meets stringent safety requirements.

4. Easy Replacement: The FIT pump shares the same bolt-down footprint and inlet/discharge connections as Wilden clamped pumps. This makes replacement straightforward and convenient.
