  • 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.


Switch Your Pump to an Expert Series

  • Ingersoll Rand / ARO has made it as simple as possible for you to switch to the Expert Series (EXP) line of air operated double diaphragm pumps. If you presently use a Wilden® "P4", "T4" or "M4" pumps, or a Versa-Matic® "E4" pump, you can now upgrade to EXP with minimal effort. The PW10X-X EXP pump uses the same footprint and fluid inlet/ outlet dimensions as the previously mentioned Wilden® and Versa-Matic® models. Leave the stalling issues and leaking band-clamps behind. Switch to EXP and watch energy efficiency go up while downtime and repair costs go down.
