If your mains water pressure is too low for effective reverse osmosis filtration, a booster pump is the solution. This compact, reliable pump increases the water pressure entering your RO membrane — improving output volume and purification efficiency significantly. RO membranes typically require a minimum of 40–60PSI to operate effectively. In many UK homes and properties — especially those in rural areas, upper floors, or with older pipework — mains pressure falls below this threshold. The result is slow output, wasted water, and reduced membrane performance. A booster pump solves all of this. Key Features: • Boosts inlet pressure to optimal RO operating of 100psi • Compact design — fits easily within standard under-sink or utility cupboard installations • Compatible with most domestic and semi-commercial RO systems • Quiet operation • Improves both output flow rate and contaminant rejection efficiency • Simple inline installation — connects directly to RO feed line 50GPD requires 24V DC, 0.8A Power Supply 75GPD requires 24V DC, 0.9A Power Supply 100GPD requires 24V DC, 1.1A Power Supply 200GPD requires 24V DC, 1.8A Power Supply 400GPD requires 24V DC, 2.4A Power Supply 600GPD requires 24V DC, 3.3A Power Supply 800GPD requires 24VDC, 3.6A Power Supply 1,000GPD requires 24VDC, 4.5A Power Supply 1,200GPD requires 24V DC 5.2A Power Supply 📋 How to use: If you are unsure whether you need a booster pump, a simple pressure gauge on your cold water supply will tell you. Anything below 50PSI will benefit from boosting. Free Delivery
