Built around two Calpeda MXH 1606 horizontal multistage pumps, the BS2F 2MXH 1606 packaged booster station supplies up to 833.4 L\/Min of combined flow. To overcome static elevation and pipe friction, the wet end can generate up to 68 m of head. Its twin-pump configuration provides dependable hydraulic redundancy and high-pressure stability across hospitals, multi-level residential towers, and commercial plant rooms.\u003c\/p\u003e\u003cp\u003eDischarge line regulation is managed by calibrated differential pressure switches feeding directly into an onboard microprocessor control board. When a tap or valve opens, the primary pump engages to satisfy baseline demand, and the secondary unit steps in automatically if pressure continues to dip under heavy draw-off. Sequential duty sharing swaps the lead role between both pumps on subsequent starts, while anti-cycling timers eliminate nuisance chattering across the contactors.\u003c\/p\u003e\u003cp\u003eAll wetted collection pipework features hygienic stainless steel AISI 304 suction and delivery headers engineered for low friction loss. Plumbers can connect building mains directly to the 80 mm inlet manifold and route boosted water through the 65 mm outlet header. Integrated isolation ball valves and non-return check valves simplify individual pump servicing, while a dial pressure gauge and a dedicated mounting point for an external accumulator vessel streamline commissioning.\u003c\/p\u003e\u003cp\u003eEnergizing the booster skid requires a three-phase 415 V electrical feed matched to high-efficiency motors rated at three-phase 400\/690 V. Both 2-pole induction units operate at a synchronous speed near 2900 rpm at 50 Hz, with each motor producing 4 kW (P2) of mechanical output and drawing 5.5 A at full load. Built in strict compliance with IEC 60034 standards and protected by Class F insulation, these drives endure demanding duty cycles.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHigh-Head Impeller Stack: Utilises a precision 6-stage hydraulic assembly in each pump to overcome tall static heads and long pipe runs.\u003c\/li\u003e\n\u003cli\u003eMicroprocessor Sequencing: Coordinates differential pressure switches to stage the second pump online only when flow demand exceeds single-pump capacity.\u003c\/li\u003e\n\u003cli\u003eBalanced Wear Cycling: Alternates lead and standby pump assignments automatically to prevent premature bearing and mechanical seal fatigue.\u003c\/li\u003e\n\u003cli\u003eAISI 304 Stainless Headers: Resists corrosion and thermal stress across the suction and discharge manifolds in commercial hot and cold water loops.\u003c\/li\u003e\n\u003cli\u003eIndependent Branch Isolation: Equipped with heavy-duty ball valves and non-return valves so maintenance never forces a total building shutdown.\u003c\/li\u003e\n\u003cli\u003eWide Thermal Operating Window: Engineered to pump liquids reliably across temperatures ranging from -15 °C to +110 °C without performance degradation.\u003c\/li\u003e\n\u003cli\u003eDust and Splash Defence: Protected to IP54 ingress standards, keeping electrical terminals and motor windings safe in damp mechanical rooms.\u003c\/li\u003e\n\u003cli\u003eTurnkey Plant Assurance: Arrives fully assembled on a steel skid frame and supported by a 24 Months warranty for long-term peace of mind.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eWhat's Included\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e2 x Calpeda MXH 1606 horizontal multistage pumps\u003c\/li\u003e\n\u003cli\u003eStainless steel AISI 304 suction manifold\u003c\/li\u003e\n\u003cli\u003eStainless steel AISI 304 delivery manifold\u003c\/li\u003e\n\u003cli\u003eIsolation ball valves\u003c\/li\u003e\n\u003cli\u003eNon-return valves\u003c\/li\u003e\n\u003cli\u003eMicroprocessor control board with differential pressure switches\u003c\/li\u003e\n\u003cli\u003eSystem pressure gauge\u003c\/li\u003e\n\u003cli\u003eFactory assembled and tested boosting plant\u003c\/li\u003e\n\u003cli\u003eSupports a 1000 L galvanised diaphragm expansion tank\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":51423235211511,"sku":"BS2F 2MXH 1606*","price":23294.7,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-bs2f-2mxh-1606-three-phase-2-x-4kw-fixed-speed-twin-pump-multistage-booster-system.png?v=1793070879","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-bs2f-2mxh-1606-three-phase-2-x-4kw-fixed-speed-twin-pump-multistage-booster-system","provider":"Foundation Pumps","version":"1.0","type":"link"}
