P25 Features
The Wilden® bolted plastic air-operated double-diaphragm (AODD) pump combines maximum performance and efficiency with superior containment. Wilden's bolted-construction pumps offer improved flow rates and a redesigned liquid path that reduces internal friction for maximum output and longer diaphragm life.
- NPT or BSPT threaded inlet/discharge liquid connections
- Decades of proven performance
- Bolted construction for superior containment
- Large-solids passage
- High suction lift
- Ease of operation and maintenance
- Increased on/off reliability
- Longest Mean Time Between Repair (MTBR)
