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

32s stainless

The Model 32S control panel is designed to alternately control two three phase pumps in industrial and commercial water and sewage systems using the robust DPC-4F Pump Control Four Float Controller for pump sequence, alternation, selection, lag pump delay time and alarm.

If a high water alarm condition occurs, the high water alarm float activates the audible/visual alarm system along with auxiliary contacts for remote alarm. Common applications include lift stations and pump chambers. Models available with intrinsically safe relay for circuit extension into hazardous locations.
