CIRCULATION PUMP & PARTS 3/4
The Johnson 3/4” pump features a magnetically driven impeller and draws 2.1 Amps @ 12 VDC. It should only be used in smaller systems with less than 5 cabin fans and less than 100 feet of total hose run. It is an excellent choice as an engine pre-heat pump and because of its small size, an excellent choice for multi-pump manifold systems
