Model 32S

Three Phase Duplex Alternating Pump Control with Override in Stainless Steel Enclosure

The 32S three phase duplex control panel is designed to be rugged, simple and versatile. One panel handles three voltages and covers a wide variety of pump motor amperage requirements by simply field installing overload modules - up to 32 amps each!

House in a NEMA 4X stainless steel enclosure, this industrial grade control panel is designed to alternately control two three phase pumps in industrial and commercial water and sewage systems using standard four float operation (off, lead start, lag start, high level).  Simply add the appropriate overload modules to complete your installation (sold separately).

The alternating action equalizes pump wear and this system provides time delayed override control should either pump fail.  The panel feature seal fail indicators, thermal cutout and elapsed time meters for each pump.  If a high water alarm condition occurs, the alarm switch activates the audible/visual alarm system, along with auxiliary contacts for remote alarm.  Common applications include lift stations, pump chambers and irrigation systems.
