ps420-metal

The Wilden® PS420 – 1 1/2″ / 38 mm Advanced™ FIT Metal AOD pumps are available in stainless steel or alloy C. Pipe connections are NPT or BSPT threads. The PS420 is available in a horizontal or vertical configuration.

They come equipped with the Pro-Flo® SHIFT Air Distribution System (ADS) that provides 60% savings in air consumption, more yield per SCFM, precisely metered air consumption for less product waste and maximum Mean Time Between Repair (MTBR). Available Pro-Flo SHIFT center section materials are aluminum, nickel-plated aluminum, stainless steel and polypropylene.

Elastomers are available in the following materials:

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

Multiple options are available to meet your specific application requirements.
