Pairing 2 Calpeda MXHLM 406 horizontal multistage pumps on a shared skid, this unit delivers up to 266.6 L\/Min of flow. Up to 63 m of delivery head can be developed to keep upper-level fixtures properly pressurised. Its high-pressure output overcomes steep elevation changes and long pipe runs effortlessly.\u003c\/p\u003e\u003cp\u003ePrecise staging across both pumps relies on differential pressure switches with a microprocessor control board that continuously monitors discharge pressure. A single duty pump handles light to moderate water usage, while the second pump engages automatically whenever simultaneous fixture demand pulls pressure down further. Automatic duty alternation swaps the lead role between starts to equalise mechanical wear, supported by anti-cycling switch calibration that stops rapid starting.\u003c\/p\u003e\u003cp\u003eHeavy-duty stainless steel AISI 304 suction and delivery headers provide a clean, rust-proof fluid pathway suited to potable and heated water loops. The manifold assembly offers a 50 mm suction connection and a 40 mm discharge connection for straightforward pipework integration. Every branch is fitted with isolation ball valves and non-return check valves, complemented by a system pressure gauge and a pre-installed port for an external accumulator tank.\u003c\/p\u003e\u003cp\u003eEngineered for maximum output on standard building power, both the electrical supply and motor windings use a single-phase 230 V configuration. Each 2-pole induction drive spins at approximately 2900 rpm (50 Hz), delivering a robust 1.5 kW (P2) per pump while drawing 9.2 A at full load. Built in accordance with IEC 60034 standards and protected by Class F insulation, the motors ensure dependable operation under heavy thermal and hydraulic loads.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eMaximum Six-Stage Lift: Employs a 6-stage stainless steel hydraulic assembly to produce high discharge head alongside strong volumetric flow.\u003c\/li\u003e\n\u003cli\u003eIntelligent Cascade Alternation: Rotates lead and assist assignments automatically via the microprocessor board so both pumps share running hours equally.\u003c\/li\u003e\n\u003cli\u003eHygienic Stainless Collectors: Fabricated with AISI 304 stainless steel suction and delivery manifolds to ensure long-term corrosion resistance.\u003c\/li\u003e\n\u003cli\u003eBroad Liquid Temperature Rating: Handles cold and hot water boosting applications across a wide operating window of -15 °C to +110 °C.\u003c\/li\u003e\n\u003cli\u003eDurable Enclosure Sealing: Constructed to IP54 protection standards to guard motor windings and control electronics against dust and water splashes.\u003c\/li\u003e\n\u003cli\u003eUninterrupted Servicing Design: Pairs individual isolation ball valves with non-return check valves so either pump can be maintained while the system stays live.\u003c\/li\u003e\n\u003cli\u003eAnti-Cycling Switch Control: Utilises precision differential pressure switches with electronic timing logic to eliminate rapid on-off motor chattering.\u003c\/li\u003e\n\u003cli\u003ePre-Tested Skid Package: Shipped factory assembled and pressure-verified on a sturdy steel frame with the support of a 24 Months warranty.\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 MXHLM 406 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 200 L galvanised diaphragm expansion tank\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":51423236325623,"sku":"BSM2F 2MXHLM 406","price":14765.3,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-bsm2f-2mxhlm-406-single-phase-2-x-1-5kw-fixed-speed-twin-pump-multistage-booster-system.png?v=1793070920","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-bsm2f-2mxhlm-406-single-phase-2-x-1-5kw-fixed-speed-twin-pump-multistage-booster-system","provider":"Foundation Pumps","version":"1.0","type":"link"}
