The SOR 4NN-K45-N4-B1A Caustic Pump Pressure Switch is an industrial-rated device designed to monitor and control caustic pump systems. It uses SPDT dry-contact output (N4) and comes in a rugged B1A enclosure, engineered to withstand corrosive chemical service in demanding environments. The unit provides an adjustable setpoint to switch a pump or control circuit when system pressure reaches the programmed value, making it suitable for chemical processing, water treatment, and other industrial pump installations that require reliable, automatic pressure control.
