Wilden PX420 38 mm (1 1/2”) FIT Metal AOD Pump See all Brands

Upgrading older pump technology with the PX420 gives improved bolted product containment, greater reliability, easier maintenance and more efficient operations with no repiping for cost savings and fast ROI. In addition to its exact bolt and pipe match, the PX420’s flexibility in aligning the wetted path assembly through lateral adjustment of the manifolds greatly facilitates easier installation into poorly piped systems.

Available wetted path materials are stainless steel or alloy C. Pipe connections are NPT or BSPT threads. The PX420 is available in a horizontal or vertical configuration.

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.

  • Buna-N
  • EPDM
  • Geolast®
  • Neoprene
  • Polyurethane
  • PTFE
