Combining two Calpeda MXH 3203 horizontal multistage pumps on a unified skid, the BS2F 2MXH 3203 twin booster set delivers up to 1666.6 L\/Min of full-load flow. Up to 50 m of delivery head can be developed to keep upper-level fixtures properly pressurised. This heavy-duty dual-pump package ensures unwavering pressure stability across high-demand pipe networks.\u003c\/p\u003e\u003cp\u003eAutomatic lead-lag staging is governed by calibrated differential pressure switches connected to an onboard microprocessor control board. When downstream fixtures open, the primary pump starts immediately to hold line pressure, and the secondary pump cascades online only if consumption outstrips single-pump capacity. Sequential duty alternation swaps the lead role after every cycle to equalise mechanical wear, while anti-cycling timers prevent rapid contactor switching.\u003c\/p\u003e\u003cp\u003eHeavy-gauge stainless steel AISI 304 suction and delivery headers provide corrosion-free fluid collection and low friction loss under high flow rates. The manifold assembly incorporates a 100 mm suction inlet and an 80 mm discharge outlet, complete with individual isolation ball valves and non-return check valves on each pump leg. An integrated system pressure gauge and a dedicated connection port for an external diaphragm tank simplify site installation.\u003c\/p\u003e\u003cp\u003eBoth pumps are powered by a three-phase 415 V site supply feeding high-efficiency motors wound for three-phase 400\/690 V operation. Each 2-pole induction motor runs at approximately 2900 rpm on a 50 Hz supply, producing 5.5 kW (P2) of mechanical power and drawing 6.2 A at full load. Engineered in accordance with IEC 60034 standards and protected by Class F insulation, these drives withstand continuous commercial duty.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHigh-Flow Multistage Lift: Utilises a robust 3-stage stainless steel hydraulic assembly in each pump to combine massive flow with strong vertical head.\u003c\/li\u003e\n\u003cli\u003eIntelligent Cascade Switching: Differential pressure switches and microprocessor logic stage the assist pump online smoothly during peak demand.\u003c\/li\u003e\n\u003cli\u003eAutomatic Duty Alternation: Rotates primary and standby assignments between cycles so both pumps accumulate balanced operating hours.\u003c\/li\u003e\n\u003cli\u003eHygienic AISI 304 Manifolds: Stainless steel suction and delivery headers resist internal corrosion and maintain clean water quality.\u003c\/li\u003e\n\u003cli\u003eIndependent Valve Isolation: Equipped with full-bore ball valves and check valves to allow single-pump servicing without system shutdowns.\u003c\/li\u003e\n\u003cli\u003eBroad Thermal Versatility: Operates reliably across liquid temperatures from -15 °C to +110 °C in chilled or heated water circuits.\u003c\/li\u003e\n\u003cli\u003eSealed Plant-Room Protection: Constructed to IP54 ingress standards to guard motors and control boards against dust and water splashes.\u003c\/li\u003e\n\u003cli\u003eFactory Tested Reliability: Delivered fully assembled, pre-wired, and backed by a 24 Months manufacturer 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 MXH 3203 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 2000 L galvanised diaphragm expansion tank\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":51423235473655,"sku":"BS2F 2MXH 3203*","price":28375.6,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-bs2f-2mxh-3203-three-phase-2-x-5-5kw-fixed-speed-twin-pump-multistage-booster-system.png?v=1793070897","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-bs2f-2mxh-3203-three-phase-2-x-5-5kw-fixed-speed-twin-pump-multistage-booster-system","provider":"Foundation Pumps","version":"1.0","type":"link"}
