Commercial Grade reverse osmosis booster pump 300 gpd.
300 GPD Reverse Osmosis Booster Pump
Improve the operating pressure and performance of your residential or light-commercial reverse osmosis system with this 24V 300 GPD RO booster pump. Designed for reverse osmosis membranes rated up to 300 GPD, this pump is ideal for systems with low municipal water pressure, well-pressure tanks, slow storage-tank filling, or continuous drain-water flow caused by insufficient feed pressure.
The pump helps deliver stronger and more consistent pressure to the RO membrane, supporting improved membrane efficiency, more reliable purified-water production, and faster storage-tank filling under low-pressure conditions.
Recommended for Low-Pressure Installations: This booster pump is recommended when incoming city-water pressure is below approximately 50 PSI or when the RO system is supplied by a well-pressure tank operating around 40–60 PSI.
Consider This Booster Pump If:
- Your RO storage tank takes more than two hours to fill
- Your system continuously sends water to the drain
- Your incoming water pressure is below approximately 50 PSI
- Your 300 GPD membrane is not reaching its expected output
- Your system is supplied by a well-pressure tank
This Pump May Not Be Suitable If:
- Your city-water pressure is consistently 55 PSI or higher
- You only want to increase water flow to a refrigerator, ice maker, or RO faucet
Increasing delivery flow from the RO storage tank to a faucet, refrigerator, or ice maker normally requires a delivery pump or demand pump, which is a different product.
