Pump package for cold weather

Thompson Pump & Manufacturing Co launched its Arctic Knight cold weather pump package at WEFTEC. The Arctic KnightT is a simple and reliable cold weather package which allows a diesel-driven pump to be used in climates as cold as 40 degrees below Fahrenheit. The system eliminates the traditional problems of operating pumps in cold climates such as frozen liquids in the pump, cracked pump housings, and engine starting problems, Thompson says. It also eliminates the need for expensive and often unreliable accessory items such as block heaters, fuel heaters, and glow plugs.

The Arctic Knight system is completely independent and does not require other equipment such as generators or auxiliary heaters to operate, and no modifications are needed for the pump to operate in temperatures ranging from 40 degree below 0 to 110 degrees Fahrenheit. In fact, the actual desired temperature inside the enclosure can be pre-set and locked to allow for the most efficient operation, Thompson says.

The Arctic Knight also feature an automatic start and stop which allows the pump to be turned on and off automatically based on the liquid level, allowing for unmanned operation, which is especially desirable for frigid temperatures.

The Arctic Knight works via a self-contained, thermostat controlled heating system which operates from the on-board fuel supply to regulate and maintain the temperature inside the enclosure. To prevent liquids from freezing when the pump is off, an auto-drain feature automatically drains the fluid inside the pump and piping system. Unlike conventional automatic drain valves, this system does not require external electrical power to operate. The auto-drain achieves a much higher closing force that prevents debris from interfering with the operation of the valve.
