The purpose of the reverse osmosis booster pump is to increase water pressure going into the RO unit. Reverse osmosis is a pressure-driven process. Small residential RO units will theoretically operate on very low pressure--down to 35 psi, according to some membrane makers--but the reality is, you won't get a lot of water and the product water quality will be compromised if the unit runs below 45 psi. Low inlet pressure makes the unit produce more reject water, produce less drinking water, fill the storage tank more slowly, and produce lower quality water. RO units run well on typical city water pressure of 60 psi, but they run even better with a small pump to boost the pressure to 80 psi or higher. Boosting pumps are to be used in applications where the normal water pressure feeding a system is low and needs to be increased - where you want to boost water pressure. The typical reverse osmosis (RO) system requires at least 50 psi feeding the system in order to function properly. If the water pressure feeding an RO system is less than 50 psi, the system will produce less water and at a lower quality. The water pressure boosting pumps are designed specifically for increasing the water pressure (boost water pressure) to pre-water treatment (RO boost) applications. Most booster pumps require a pressure switch and transformer.100% GENUINE AQ&Q DIAPHRAGM PUMP INPUT VOLTAGE 24VDC OR 24VAC 1/4" QUICK FIT CONNECTOR & 3/8"-18 NPT FEMALE ARE AVAILABLE PUMP CAN RUN DRY WITHOUT DAMAGE QUITE PERFORMANCE & LOW VIBRATION SANTOPRENE & PLOYAMIDE MATERIAL
