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.
