Description
The RO Booster Pump 100 GPD is a compact 24V diaphragm pump that increases the pressure feeding a home reverse osmosis membrane. RO membranes need good pressure to work properly: below about 40 psi, output drops, the tank fills slowly, and more salt passes through. Many homes in Oman are fed from rooftop tanks with low pressure, so a booster pump is often essential for a good RO system.
Signs you need an RO Booster Pump
- RO storage tank takes many hours to fill
- Weak flow from the RO faucet
- Rising TDS in RO water
- Supply from a rooftop tank or gravity feed
- Large volume of water going to drain compared with product water

How it fits into an RO system
The pump sits after the pre-filters and before the membrane. A low pressure switch protects it from running dry, and a high pressure switch stops it when the tank is full. Some systems also add a solenoid valve to stop water flow when the pump is off. We can supply the full kit and wire it correctly. See related RO spare parts and accessories and complete RO systems.
