HHO hydrogen on deman system electrolyte flow pump. Using a flow pump with your hydrogen system will increase efficiency by as much as 25%. It will also allow your system to run up to 50% cooler. When you run a hydrogen generator or HHO cell you will notice that the electrolyte solution becomes instantly cloudy with gas micro bubbles. These micro bubbles occupy your electrode surface by as much as 50% , using this flow pump purges the bubble saturated water from your cell quickly, freeing up precious electrode surface area. Most cells on the market also use a self circulating system for cooling. This requires a small gass pressure to build in the cell so sufficient Pressure is obtained to maintain pumping. This pressure has a heating effect on your cell ,(same principle as a pressure cooker in your kitchen.. normal temp of boiling water is 212F temp of water in a pressure cooker can reach 350F)
