Engineered with two horizontal multistage Calpeda MXHL 406 pumps, the BS2F 2MXHL 406 package delivers up to 266.6 L\/Min of flow. Up to 63 m of head is available to maintain line pressure across elevated risers. Combining twin pumps on one frame ensures high-pressure delivery during peak occupancy alongside dependable standby cover.\u003c\/p\u003e\u003cp\u003eHydraulic steadiness across the distribution network is managed by differential pressure switches wired into a central microprocessor control board. Under light usage, a single pump satisfies the building, whereas heavier simultaneous draw triggers sequential staging of the second unit. Built-in duty alternation swaps the lead and lag roles between starts, while anti-cycling logic cushions the contactors against rapid pressure fluctuations.\u003c\/p\u003e\u003cp\u003eWelded from rust-proof stainless steel AISI 304, the suction and discharge manifolds provide a clean, low-turbulence pathway for potable or heated water. The pipework pairs a 50 mm inlet header with a 40 mm outlet manifold, incorporating a direct connection point for an external diaphragm tank and a dial pressure gauge. Full-flow isolation ball valves and check valves on each branch allow individual pump isolation without draining the main line.\u003c\/p\u003e\u003cp\u003eFrom an electrical standpoint, the control panel connects to a three-phase 415 V supply to run motors rated at three-phase 230\/400 V. Each 2-pole induction unit turns at approximately 2900 rpm on 50 Hz power, delivering 1.5 kW (P2) per pump with a rated full-load current of 3.6 A. Built to IEC 60034 standards with Class F winding insulation, the motors offer high thermal margins under sustained load.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eMaximum Lift Configuration: Employs a 6-stage impeller arrangement per pump to overcome steep static heads and friction losses in long pipe runs.\u003c\/li\u003e\n\u003cli\u003eAutomated Demand Staging: Combines differential pressure switches with a microprocessor board to engage the second pump only when system pressure drops.\u003c\/li\u003e\n\u003cli\u003eCyclic Duty Alternation: Switches the lead pump assignment automatically to keep bearings, seals, and windings evenly exercised.\u003c\/li\u003e\n\u003cli\u003eAll-Stainless Fluid Path: Combines AISI 316L pump wet ends with AISI 304 headers to preserve water quality and resist chemical attack.\u003c\/li\u003e\n\u003cli\u003eExtended Thermal Range: Certified for liquid temperatures between -15 °C to +110 °C, suiting both chilled loops and hot water boosting.\u003c\/li\u003e\n\u003cli\u003eIndividual Branch Shut-Off: Fits check valves and ball valves to each pump leg so routine maintenance never halts building water supply.\u003c\/li\u003e\n\u003cli\u003eSealed Industrial Motors: Rated to IP54 for dust and splash resistance, complemented by high-grade Class F electrical insulation.\u003c\/li\u003e\n\u003cli\u003eFactory-Verified Assembly: Shipped pre-plumbed and electrically tested on a rigid base with a mounted system pressure gauge.\u003c\/li\u003e\n\u003cli\u003eTwo-Year Protection Plan: Backed by a 24 Months manufacturer warranty for commercial dependability.\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 MXHL 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":51423234916599,"sku":"BS2F 2MXHL 406","price":14226.3,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-bs2f-2mxhl-406-three-phase-2-x-1-5kw-fixed-speed-twin-pump-multistage-booster-system.png?v=1793070860","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-bs2f-2mxhl-406-three-phase-2-x-1-5kw-fixed-speed-twin-pump-multistage-booster-system","provider":"Foundation Pumps","version":"1.0","type":"link"}
