Features and Benefits

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.

  • DIN or ANSI flanged inlet/discharge liquid connections
  • Featuring the energy-efficient Pro-Flo® SHIFT ADS
  • Greater flow - more gallons pumped per SCFM
  • Reduced air consumption and kilowatt usage
  • 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)
