Model 322

Three Phase Duplex Alternating Pump Control with Override

The Model 322 Build-A-Panel™ control panel provides greater flexibility by ordering through options, allowing you to customize a standard panel to your specific needs.

The Model 322 control panel provides commercial and industrial customers a reliable means of controlling one 208/240/480V three phase pump in water and sewage installations.

The alternating action equalizes pump wear.  In addition, this system provides override control should either pump fail.  If an alarm condition occurs, the alarm switch activates the audio/visual alarm system.

Common applications include pump chambers, irrigation systems and lift stations.
