Reverse osmosis (RO) pumps are devices used in reverse osmosis systems to increase the water pressure going into the RO membrane. This elevated pressure is crucial for forcing water molecules through the semi-permeable membrane while rejecting contaminants, such as salts, minerals, and other impurities. By boosting pressure, RO pumps enhance water flow rates, improve filtration efficiency, and increase the overall production of purified water. These pumps are particularly useful in low-pressure situations or where high-quality water output is desired.
