The Calpeda BSM2F 2MXHLM 404 twin booster assembly integrates 2 Calpeda MXHLM 404 horizontal multistage pumps to deliver up to 266.6 L\/Min of flow. To support elevated outlets and long pipe runs, the package can deliver up to 40.5 m of head. This dual-pump configuration provides reliable peak-load boosting alongside full standby security.\u003c\/p\u003e\u003cp\u003eBalanced handoffs between the duty and assist pumps is handled by differential pressure switches with a microprocessor control board. Rather than running both motors continuously, the system activates one pump for routine demand and stages the second unit in only when heavy water usage drops line pressure further. Automatic duty alternation swaps the lead pump after each stop, while anti-cycling pressure switch logic protects the starters from rapid cycling.\u003c\/p\u003e\u003cp\u003eEvery primary fluid collector on the frame is fabricated from corrosion-resistant stainless steel AISI 304 to ensure hygienic operation in potable water networks. Site pipework mates cleanly with a 50 mm inlet and a 40 mm outlet engineered to reduce turbulence at higher flow velocities. Dedicated isolation ball valves, spring-loaded check valves, an analogue system pressure gauge, and a connection port for an external expansion vessel come factory fitted.\u003c\/p\u003e\u003cp\u003eBoth the control panel supply and the pump motor windings operate on a single-phase 230 V electrical rating, allowing straightforward installation without three-phase mains. Each 2-pole induction motor runs at approximately 2900 rpm (50 Hz), producing 0.75 kW (P2) per unit and drawing 5.7 A under full load. Compliant with IEC 60034 construction standards and protected by Class F insulation, the motors are built for continuous commercial duty.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFour-Stage Hydraulic Lift: Features a 4-stage stainless steel impeller assembly that boosts both volumetric flow and discharge pressure for multi-storey plumbing.\u003c\/li\u003e\n\u003cli\u003eAutomated Duty Alternation: Balances running hours across both pumps automatically through the microprocessor controller to extend mechanical seal life.\u003c\/li\u003e\n\u003cli\u003eHygienic AISI 304 Pipework: Uses stainless steel suction and delivery manifolds to prevent rust formation in domestic cold and hot water systems.\u003c\/li\u003e\n\u003cli\u003eWide Temperature Capability: Engineered to pump liquids safely across a thermal range extending from -15 °C to +110 °C.\u003c\/li\u003e\n\u003cli\u003eEnclosure Ingress Protection: Rated to IP54 standards to shield internal electrical boards and motor windings from moisture spray and dust.\u003c\/li\u003e\n\u003cli\u003eIndependent Valve Isolation: Fitted with individual ball valves and non-return check valves so maintenance can proceed without shutting off building water supply.\u003c\/li\u003e\n\u003cli\u003eAnti-Cycling Pressure Control: Combines differential pressure switches with electronic delay timers to maintain steady line pressure without rapid switching.\u003c\/li\u003e\n\u003cli\u003eComplete Turnkey Assembly: Supplied pre-assembled and pressure-tested on a heavy-duty skid frame with 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 MXHLM 404 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":51423236260087,"sku":"BSM2F 2MXHLM 404","price":12999.8,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-bsm2f-2mxhlm-404-single-phase-2-x-0-75kw-fixed-speed-twin-pump-multistage-booster-system.png?v=1793070915","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-bsm2f-2mxhlm-404-single-phase-2-x-0-75kw-fixed-speed-twin-pump-multistage-booster-system","provider":"Foundation Pumps","version":"1.0","type":"link"}
