CAT PUMPS introduces the MAG-JET Valve for jetting. The MAG-JET uses a special SS magnetic valve and a corrosion-resistant magnet to hold on inlet valve open, creating a strong pulse-jetting action "to power nozzles through the toughest clogs."

When the MAG-JET holds the valve open, it reduces the pump flow by 1/3, causing the desired pulsations for effective jetting. Holding the valve open permits the pumping chamber to see liquid at all times, eliminating exposure to extreme vacuum conditions.
