PX820 51 mm (2") Advanced FIT Metal AOD Pump See all Brands

The Wilden® PX820 – 2" / 51 mm Advanced™ FIT bolted metal AOD pumps are available in aluminum or stainless steel. Pipe connections are NPT or BSPT threads. The PX820 replaces the PX800 Drop-In.

They come equipped with the Pro-Flo X™ Air Distribution System (ADS) that provides superior flow rates, variable control, the patented Efficiency Management System (EMS™), maximum Mean Time Between Repair (MTBR) and lube-free operation.

Elastomers are available in the following materials:

  • Buna-N
  • EPDM
  • Geolast®
  • Neoprene
  • Polyurethane
  • PTFE
  • Saniflex™
  • Viton®
  • Wil-Flex™
