Featuring 2 Calpeda MXHLM 403 horizontal multistage pumps, the Calpeda BSM2F 2MXHLM 403 booster set supplies up to 266.6 L\/Min of combined flow. Where high-pressure boosting is needed, the hydraulic stages can produce up to 30 m of head. Its dual-pump architecture guarantees consistent water delivery when multiple showers and taps operate simultaneously.\u003c\/p\u003e\u003cp\u003ePressure regulation across the manifold is managed by differential pressure switches with a microprocessor control board that tracks real-time demand. One pump serves as the primary duty unit during light usage, while the assist pump stages in automatically whenever high-volume draw-offs cause header pressure to dip. Automatic duty alternation rotates the lead pump after every run cycle, and anti-cycling switch calibration prevents rapid motor restarts.\u003c\/p\u003e\u003cp\u003eBuilt for multi-decade life in potable and hot-water service, the skid uses hygienic stainless steel AISI 304 suction and delivery manifolds. The pipework features a 50 mm suction inlet and a 40 mm discharge outlet sized to accommodate higher flow rates with minimal head loss. Individual isolation ball valves, non-return check valves, a direct-reading system pressure gauge, and an external vessel connection port are pre-installed on the headers.\u003c\/p\u003e\u003cp\u003ePowering the package is simple in residential and light commercial buildings because both the incoming feed and motor windings utilise single-phase 230 V electricity. Running at a nominal 2900 rpm (50 Hz), each 2-pole induction motor is rated at 0.55 kW (P2) and draws 4.5 A during full-load operation. Full adherence to IEC 60034 motor specifications and Class F winding insulation ensure dependable, low-noise performance.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBalanced Multistage Output: Uses a 3-stage stainless steel impeller arrangement to deliver generous flow capacity alongside steady medium-head boosting.\u003c\/li\u003e\n\u003cli\u003eIntelligent Lead-Lag Staging: Coordinates sequential pump activation and automatic duty changeover via the onboard microprocessor to equalise component wear.\u003c\/li\u003e\n\u003cli\u003eAISI 304 Stainless Manifolds: Provides corrosion-free fluid distribution across both the suction and discharge collectors for clean potable water handling.\u003c\/li\u003e\n\u003cli\u003eHot and Chilled Liquid Support: Rated for continuous operation with fluid temperatures ranging from -15 °C to +110 °C across diverse plumbing circuits.\u003c\/li\u003e\n\u003cli\u003eDust and Splash Guarding: Built with IP54 environmental protection to keep electrical terminals and motor housings safe in damp plant areas.\u003c\/li\u003e\n\u003cli\u003eIsolated Maintenance Access: Integrates full-bore ball valves and check valves on each branch so one pump can be serviced while the other maintains pressure.\u003c\/li\u003e\n\u003cli\u003eStable Differential Switching: Relies on precision pressure switches with anti-cycling logic to eliminate contactor chattering and pressure surges.\u003c\/li\u003e\n\u003cli\u003eFactory Tested Dependability: Arrives pre-wired and fully tested on a rigid steel baseplate with coverage from 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 403 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":51423236227319,"sku":"BSM2F 2MXHLM 403","price":12760.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-bsm2f-2mxhlm-403-single-phase-2-x-0-55kw-fixed-speed-twin-pump-multistage-booster-system.png?v=1793070913","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-bsm2f-2mxhlm-403-single-phase-2-x-0-55kw-fixed-speed-twin-pump-multistage-booster-system","provider":"Foundation Pumps","version":"1.0","type":"link"}
