Self-Regulating Booster Pump for 36gpd to 150gpd RO Systems

Maximize your reverse osmosis system's performance with this premium self-regulating booster pump kit from Osmotics—designed specifically for domestic 36–150 GPD RO units. 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 through lower water bills and less rejected water.

The standout feature is built-in self-regulation integrated directly into the pump head—no external tubing or add-ons needed. This smart design automatically adjusts output to prevent over-pressurisation, protecting your RO membrane from stretching, delamination, or premature failure (a common issue with basic booster pumps on variable-pressure supplies).

This latest model includes robust anti-vibration feet—a UK first—for noticeably quieter operation, making it ideal for under-sink or utility-room installations where noise matters.

Key Benefits

• Full membrane capacity — Boosts low-pressure supplies to deliver up to 100% of your RO membrane's rated output (e.g., a 50 GPD membrane produces closer to 50 gallons/day instead of 20–30).
• Membrane protection — Self-regulating mechanism caps pressure to avoid damage, extending membrane life (typically 2–3 years → longer).
• Reduced waste water — Better recovery rates mean less water down the drain—eco-friendly and cost-saving.
• Ultra-quiet & vibration-free — Anti-vibration feet minimize noise and shaking for discreet home use.
• Quick ROI — Many users see payback in 4–8 weeks via saved water and improved efficiency.
• Complete & easy install — Plug-and-play kit with everything included; low-energy draw (CE/RoHS certified).

What's Included

• 1 × Self-regulating booster pump with integrated regulation and anti-vibration feet
• Quick-connect fittings (standard 1/4" JG-style for easy tubing integration)
• UK-compatible transformer/power supply
• Installation instructions

Specifications

• Compatibility: Reverse osmosis systems from 36 GPD to 150 GPD (standard domestic models)
• Duty Cycle: Intermittent use only – maximum 6 hours continuous operation, followed by 1-hour cooldown (not suitable for commercial/window cleaning applications; contact us for heavy-duty options)
• Pressure Boost: Typically raises feed to 60–80 PSI for optimal RO performance
• Power: Low-voltage safe (via included transformer); energy-efficient
• Certifications: CE and RoHS compliant for UK/EU sale
• SKU: OS-BPASR

Important Usage Notes This pump is engineered for intermittent domestic duty (e.g., filling tanks for drinking water, aquariums, window cleaning prep, car rinsing). Do not run continuously for more than 6 hours without cooldown—prolonged use can cause overheating and failure. For commercial/high-volume needs, ask about our dedicated continuous-duty pumps.

Pair with our High Pressure Switch for automatic tank shut-off, or Low Pressure Switch for dry-run protection, to create a fully automated, safe system.

This bestselling booster pump delivers reliable, quiet, and protected performance—trusted by UK RO users for drinking water, reef aquariums, spot-free rinsing, and more.
