Most Reverse Osmosis membranes have ideal minimum pressure such as 50 psi or 60 psi. When the pressure is insufficient and the RO system will generate less drinkable water at a low purify effect. The 150 gpd ro booster pump will increase 75 psi pressure. The RO pump can be used in a water purifier of 150 gallons per day. A RO Booster Pump can generate more high purity freshwater with less rejected water. Commonly used either to pressurize water from an atmospheric tank, to deliver purified water to a specific point of use, or simply to increase pressure when required. This model is designed for both intermittent duty and continuous operation.
