Thompson Arctic Knight

Thompson Arctic Knight The Arctic Knight from Thompson Pump & Manufacturing is a cold-weather package that allows diesel-powered pumps to be used in climates as cold as minus 40F. The Arctic Knight uses a self-contained, thermostatically controlled heating system, which operates from the on-board fuel supply to regulate the temperature inside the pump enclosure. To prevent liquids from freezing when the pump is off, an auto-drain feature drains fluid from inside the pump and piping system. The drain system requires no external electric power to operate, and its powerful valve prevents debris from interfering with closure of the drain.
