Automatic Dewatering System

Air Operated Control Solution with Liquid Level Sensing

The ARO® Automatic Dewatering System offers automatic on/off controls for Pro and EXP diaphragm pumps.  A pneumatically controlled Liquid Level Sensor is used to easily control the fluid level within a desired range.  The Automatic Dewatering System will limit the monitoring labor and reduce air consumption by avoiding dry running of the pump.
