Equipped with two Calpeda MXH 2003 horizontal multistage pumps, the BS2F 2MXH 2003 twin booster set delivers a full-load flow of up to 800 L\/Min. For vertical risers and pressurised distribution lines, the pump assembly can reach up to 48.5 m of head. Its dual-pump architecture guarantees continuous water supply and adaptable capacity across fluctuating daily demand profiles.\u003c\/p\u003e\u003cp\u003eResponsibility for staging the twin pumps rests with differential pressure switches connected to a central microprocessor control board. Rather than running at full capacity during quiet periods, the system engages one pump for normal draw-off and cascades the second unit online when line pressure falls further. Automatic duty alternation switches the lead pump role on each cycle, while integrated anti-cycling timers prevent rapid start-stop wear on the contactors.\u003c\/p\u003e\u003cp\u003ePrecision-formed from durable stainless steel AISI 304, the suction and delivery manifolds ensure clean fluid transfer and minimal head loss across the skid. Site piping mates directly with the 80 mm inlet header and 65 mm discharge manifold, supported by full-flow isolation ball valves and non-return check valves on both branches. A clear pressure gauge tracks discharge performance, and a pre-fitted connection port simplifies linking an external expansion tank.\u003c\/p\u003e\u003cp\u003eEach pump is driven by a high-efficiency 2-pole induction motor operating on a three-phase 415 V supply with three-phase 230\/400 V stator windings. Spinning at approximately 2900 rpm on 50 Hz mains power, each motor produces 3 kW (P2) of output while drawing 6.6 A under full load. Built to IEC 60034 international standards with Class F insulation, the drive assembly withstands demanding thermal and mechanical loads.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBalanced Multistage Lift: Each pump utilises a precision 3-stage stainless steel wet end to combine generous flow rates with mid-range vertical head.\u003c\/li\u003e\n\u003cli\u003eCascade Pressure Switching: Differential pressure switches and microprocessor logic stage the assist pump smoothly as building consumption rises.\u003c\/li\u003e\n\u003cli\u003eAutomatic Lead-Lag Alternation: Rotates primary duty between both pumps on every start cycle to maximise mechanical seal and bearing life.\u003c\/li\u003e\n\u003cli\u003eHygienic Stainless Headers: AISI 304 suction and delivery manifolds resist rust and chemical degradation in potable and hot-water systems.\u003c\/li\u003e\n\u003cli\u003eMaintenance-Friendly Valves: Dedicated isolation ball valves and check valves let technicians service either pump without shutting off building water.\u003c\/li\u003e\n\u003cli\u003eThermal Fluid Flexibility: Handles cold and heated water circuits operating anywhere between -15 °C to +110 °C.\u003c\/li\u003e\n\u003cli\u003eSealed Industrial Protection: Rated to IP54 ingress standards to keep moisture spray and airborne particulates out of motor and control housings.\u003c\/li\u003e\n\u003cli\u003eGuaranteed Build Quality: Supplied as a factory-tested package backed by a 24 Months warranty for dependable commercial operation.\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 2003 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 800 L galvanised diaphragm expansion tank\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":51423235309815,"sku":"BS2F 2MXH 2003","price":23203.4,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-bs2f-2mxh-2003-three-phase-2-x-3kw-fixed-speed-twin-pump-multistage-booster-system.png?v=1793070886","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-bs2f-2mxh-2003-three-phase-2-x-3kw-fixed-speed-twin-pump-multistage-booster-system","provider":"Foundation Pumps","version":"1.0","type":"link"}
