Self-Regulating Booster Pump for 600gpd RO Systems

Maximise your reverse osmosis system's performance with this premium self-regulating booster pump kit from Osmotics, designed specifically for domestic 600+ GPD RO units.

Important: Understanding Pump Labelling. The pump model numbers (e.g. 400) do not refer to the RO membrane rating. They indicate the pump’s boosting capability and flow characteristics.

• A 400 pump is ideal for boosting standard low-pressure supplies to properly support up to 600 GPD membranes. It delivers the pressure and flow needed for higher-output membranes to reach their full rated production. Higher-numbered pumps provide greater boost for more demanding setups.

Example: If you have a 600 GPD+ membrane but low household water pressure, choose this pump. It boosts pressure to the optimal 60–80 PSI range so your membrane can produce close to its full rated gallons per day.

If your home water pressure is below the ideal 50–60 PSI (common in many UK areas), this pump reliably boosts feed pressure to unlock your membrane’s full rated output, dramatically increases daily production, reduces waste water ratios, and pays for itself in weeks.

The standout feature is built-in self-regulation integrated directly into the pump head, no external tubing required. This smart design automatically adjusts output to prevent over-pressurisation, protecting your RO membrane from stretching, delamination, or premature failure.

This latest model also includes robust anti-vibration feet for noticeably quieter operation.
