OSO SuperStream Charger Pump Pressure Booster For Low Mains With SuperStream Accumulators
OSO SuperStream Charger Pump (11007348) — Quiet, intelligent pressure booster pump designed exclusively for SuperStream accumulator systems | Boosts incoming mains to ~3.5 bar | Activates only on demand (very low noise ~38 dB(A)) | Bronze construction for potable water | Wall-mounted, compact | Essential when dynamic mains pressure is consistently below ~2 bar | Works seamlessly with all SuperStream accumulators & Upstream Kit
Only needed when incoming dynamic pressure is below ~2 bar (common in rural areas, tall buildings or shared supplies). The accumulator still provides peak-demand boosting even if the pump is off (e.g. power cut). No noisy constant-running pump — intelligent on-demand operation.
The OSO SuperStream Charger Pump is a specialised, low-noise booster pump created to pre-pressurise incoming mains water before it reaches the SuperStream accumulator(s) and Upstream Kit. It is **only required** in properties where the dynamic (flowing) mains pressure is consistently below approximately 2 bar — situations where even a single accumulator cannot fully compensate for very weak incoming supply (e.g. long rural runs, high-rise apartments, or properties at the end of a shared main).
Unlike traditional full-house booster pumps that run constantly and create significant noise/vibration, the Charger Pump is intelligent: it activates **only** when flow is detected and pressure drops below a threshold, then shuts off when demand stops. This results in extremely quiet operation (~38 dB(A) maximum — quieter than a normal conversation) and very low energy use. The pump is bronze-bodied for full WRAS approval and potable water safety, wall-mounted for easy installation, and designed to work in harmony with the accumulator's passive boosting — the accumulator handles short, sharp peaks while the pump maintains base pressure during prolonged demand.
Key benefit: the entire SuperStream system remains functional during power failures — the accumulator alone will still boost flow using stored pressure, albeit without the pre-boost from the pump. This makes it far more reliable than conventional pumped systems.
What Makes the SuperStream Charger Pump Special?
- Intelligent On-Demand Operation — Only runs when needed (flow detected) — silent most of the time, huge energy savings vs constant-run pumps.
- Very Low Noise — Maximum ~38 dB(A) — can be installed near living areas without disturbance (much quieter than standard booster pumps at 50–70 dB).
- Bronze Construction — WRAS-approved for direct potable water contact — safe, corrosion-resistant and long-lasting.
- Fail-Safe Design — Accumulator continues to boost during power cuts or pump downtime — no loss of basic functionality.
- Compact Wall-Mount — Small footprint, easy retrofit alongside SuperStream accumulator and Upstream Kit.
- Perfect System Match — Engineered specifically for SuperStream — no compatibility issues or over/under-boosting.
