Primex - Model 331 -Control Panel
The 331 Control Panel is designed for three phase duplex pump applications (three voltages 208/240/480 VAC, one panel). The panel utilizes the robust DPC-4F controller which provides the pump control ON & OFF sequence, pump alternation selection, lag pump delay time, and highwater alarm and float out-of-sequence alarm conditions. Models available with intrinsically safe relay for circuit extension into hazardous locations.
