Wilden PS420 – 38mm (1 1/2″) Advanced™ FIT Metal Pump

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.
