Q. What is the pressure of RO pump?

The best pressure for smaller RO Systems (producing up to 300 gallons per day) is 60 PSI whereas for bigger systems 100 PSI is recommended. In most cases a pressure booster pump is necessary if the existing pressure is lower than 40 pounds per square inch (PSI). The RO membrane's inlet pressure is increased with the help of a booster pump. Most water supply have sufficient pressure to run RO membranes (about 40 PSI). A booster pump is something to think about if want to utilize to RO system in an area with low water pressure. RO Systems benefit substantially from a booster pump even in situations when the water pressure is sufficient.
