Fits current Wilden or Versa-Matic diaphragm pump configurations

Replace Your Diaphragm Pump with ARO PW Series

ARO has made it as simple as possible for you to switch to our EXP Series line of air operated double diaphragm pumps. If you use an inefficient competitor model, leave diaphragm pump stalling issues and leaking band clamps behind. With the 1" or 2" PW Series, your pump's energy efficiency will go up while downtime and repair costs go down.

Available Models:

  • PW10A-AAX-XXX 60 GPM (227.1 LPM)

  • PW20P-YXS-XXX 184 GPM (696LPM)

Model: PW10A-AAX-XXXMaximum Flow: 60 GPM (227.1 LPM)

Features

  • Dimensional Interchange - Fits Wilden® P4, M4 and T4 pumps or Versa-Matic® E4 pump configurations. The ARO PW Series offers a dimensional interchange solution to inefficient, leaking pumps.
  • Structural Integrity - Bolted Construction eliminates problems associated with leaking band-clamps and reduces maintenance costs.
  • Matching Footprint - The Ingersoll Rand / ARO PW10X-X EXP pump has the same footprint as the Wilden® P4, M4 and T4 pumps, plus the Versa-Matic® E4 pumps.
  • Stall-Free, Ice-Free Air Motor Design -The EXP air motor has exclusive Simul-Shift valve technology for faster pump trip-over and smoother flow. It also features Quick Dump valves; the final answer to pump stalling due to ice build-up.
  • Simplified Plumbing - The Ingersoll Rand / ARO PW10X-X EXP pump matches the fluid inlet / outlet port dimensions of the Wilden P4, M4 and T4 pumps, plus the Versa-matic E4 pumps.
