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.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cp\u003eThe 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).\u003c\/p\u003e\n\n  \u003cp\u003eUnlike 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.\u003c\/p\u003e\n\n  \u003cp\u003eKey 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.\u003c\/p\u003e\n\n  \u003ch2\u003eWhat Makes the SuperStream Charger Pump Special?\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eIntelligent On-Demand Operation\u003c\/strong\u003e — Only runs when needed (flow detected) — silent most of the time, huge energy savings vs constant-run pumps.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVery Low Noise\u003c\/strong\u003e — Maximum ~38 dB(A) — can be installed near living areas without disturbance (much quieter than standard booster pumps at 50–70 dB).\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBronze Construction\u003c\/strong\u003e — WRAS-approved for direct potable water contact — safe, corrosion-resistant and long-lasting.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFail-Safe Design\u003c\/strong\u003e — Accumulator continues to boost during power cuts or pump downtime — no loss of basic functionality.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCompact Wall-Mount\u003c\/strong\u003e — Small footprint, easy retrofit alongside SuperStream accumulator and Upstream Kit.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePerfect System Match\u003c\/strong\u003e — Engineered specifically for SuperStream — no compatibility issues or over\/under-boosting.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch2\u003eKey Features\u003c\/h2\u003e\n  \u003cdiv class=\"dw-grid\"\u003e\n    \u003cdiv class=\"dw-card\"\u003e\n\u003cstrong\u003ePressure Boost\u003c\/strong\u003eRaises incoming mains to ~3.5 bar — ideal when dynamic pressure \u0026lt;2 bar.\u003c\/div\u003e\n    \u003cdiv class=\"dw-card\"\u003e\n\u003cstrong\u003eUltra-Quiet\u003c\/strong\u003eMax ~38 dB(A) — delayed start, runs only on demand.\u003c\/div\u003e\n    \u003cdiv class=\"dw-card\"\u003e\n\u003cstrong\u003eBronze Body\u003c\/strong\u003eWRAS-approved for potable water — durable \u0026amp; hygienic.\u003c\/div\u003e\n    \u003cdiv class=\"dw-card\"\u003e\n\u003cstrong\u003eEnergy Efficient\u003c\/strong\u003eProportional pumping — only boosts required portion of flow.\u003c\/div\u003e\n    \u003cdiv class=\"dw-card\"\u003e\n\u003cstrong\u003eWall-Mounted\u003c\/strong\u003eCompact design — easy install near accumulator\/Upstream Kit.\u003c\/div\u003e\n    \u003cdiv class=\"dw-card\"\u003e\n\u003cstrong\u003eFail-Safe\u003c\/strong\u003eAccumulator still boosts if pump is off (power cut or maintenance).\u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n  \u003ctable class=\"dw-spec-table\"\u003e\n    \u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003e11007348\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eCompatibility\u003c\/td\u003e\n\u003ctd\u003eSuperStream accumulators + 22\/28 mm Upstream Kit\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eBoost Output\u003c\/td\u003e\n\u003ctd\u003eUp to ~3.5 bar (when incoming \u0026lt;2 bar)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eNoise Level\u003c\/td\u003e\n\u003ctd\u003eMaximum ~38 dB(A)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eConstruction\u003c\/td\u003e\n\u003ctd\u003eBronze body (WRAS-approved)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003ePower Supply\u003c\/td\u003e\n\u003ctd\u003e230 V AC, single-phase\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eMounting\u003c\/td\u003e\n\u003ctd\u003eWall-mounted (brackets included)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eActivation\u003c\/td\u003e\n\u003ctd\u003eOn-demand (flow\/pressure sensor triggered)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eCompliance\u003c\/td\u003e\n\u003ctd\u003eWRAS, UK Water Regulations\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\n  \u003ch2\u003eWhat's in the Box\u003c\/h2\u003e\n  \u003cdiv class=\"dw-contents-grid\"\u003e\n    \u003cdiv class=\"dw-contents-item\"\u003e✔ 1 × SuperStream Charger Pump unit\u003c\/div\u003e\n    \u003cdiv class=\"dw-contents-item\"\u003e✔ Wall mounting brackets \u0026amp; fixings\u003c\/div\u003e\n    \u003cdiv class=\"dw-contents-item\"\u003e✔ Connection fittings \u0026amp; seals\u003c\/div\u003e\n    \u003cdiv class=\"dw-contents-item\"\u003e✔ Electrical \u0026amp; plumbing installation manual\u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"dw-info-box\"\u003e\n    \u003cp\u003e✅ Must be installed upstream of the Upstream Kit and accumulator(s).
