300 Gpd Reverse Osmosis Booster Pump 3000NA for Water Filter and RO System
Aliexpress UK
Was bought brand new for £70. Mounted to my RO panel with the rest of water purification equipment but never used due to exiting the hobby. The E-Chen self-regulating booster pumps are a newer model pump which will automatically stabilise the outlet pressure at 70psi when the inlet pressure is between 10-40psi. The consistent output pressure gives the advantage of prolonged RO membrane life. Will ship at buyer's own expense
