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

The Wilden® PS4 – 1-1/2" / 38 mm Stallion® Original™ Clamped Metal Air-Operated Double-Diaphragm (AODD) Pump is designed to transfer solid-laden slurries safely and effectively. Large internal clearances and flow-through design keep the pump from clogging while Wilden's patented air distribution maintains ON/OFF reliability.

Stallion technology incorporates an altered ball/seat check valve assembly that maximizes part life, increases suction lift and maximizes flow rates.

The Wilden Stallion Series ensures reliability without sacrificing ease of maintenance. With simple installation and easy serviceability, it’s ready for rugged utilitarian applications that require a robust design.

Available wetted path materials are aluminum and ductile iron.

The Wilden PS4 Stallion comes 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 material is aluminum.

Elastomers are available in the following materials:

  • Geolast®
  • Polyurethane
  • Saniflex™
  • Wil-Flex™
