Wilden PS820 – 51 mm (2″) Advanced™ FIT Metal Pump

The Wilden® PS820 – 2″ / 51 mm Advanced™ FIT bolted metal AOD pumps are available in aluminum, stainless steel or alloy C. Pipe connections are NPT or BSPT threads.

Utilising threaded inlet and discharge connections, they “fit” bolt-to-bolt and pipe-to-pipe within existing fluid-handling piping systems with no repiping. The PS820 replaces the PS800 Drop-In.

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.
