Wilden® PS4 – 1 1/2" / 38 mm Air-Operated Double-Diaphragm (AODD) Original™ Series Plastic Pump

The Wilden® PS4 – 1 1/2" / 38 mm Original™ Series clamped plastic Air-Operated Double-Diaphragm (AODD) Pump ensures reliability and cost saving operations without sacrificing ease of maintenance. With simple installation, operational efficiency and easy serviceability, it’s ready for rugged utilitarian applications that require a robust design.

Available wetted path materials are polypropylene or PVDF.

Powered by the patent-pending, energy-efficient Pro-Flo® SHIFT Air Distribution System (ADS), the PS4 provides:

  • Up to 60% savings in air consumption over competitive AODD pump technologies
  • More yield per SCFM
  • Ease of maintenance (fewest ADS parts of any AODD pump competitor)
  • Fastest ROI, lower operational cost and total cost of ownership
  • Ease of use and maximum Mean Time Between Repair (MTBR)-- Mechanically actuated, no electronic parts, submersible, no additional configuration or complicated curves

Elastomers are available in the following materials:

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