P420/P430 Features
The Wilden® bolted metal pump, also known as FIT, sets the new standard for pump performance. Featuring an enhanced flow path design, Wilden's bolted-construction pumps offer improved flow rates (up to 35% over competitive models) as well as improved diaphragm life. Wilden's bolted pumps are also designed for superior containment and have the exact bolt down footprint and inlet/discharge connections as Wilden clamped pumps for easy replacement.
- NPT or BSPT threaded inlet/discharge liquid connections (P420)
- DIN or ANSI flanged inlet/discharge liquid connections (P430) that don't require welding or nipple attachment
- Largest chemical compatibilities
- Portable and submersible
- Large-solids passage
- High suction lift
- Ease of operation and maintenance
- Flexible internal adjustment on manifolds
- Increased on/off reliability
- Longest Mean Time Between Repair (MTBR)
