Built around 2 Calpeda MXHLM 206 horizontal multistage pumps, the Calpeda BSM2F 2MXHLM 206 unit can develop up to 65 m of head for high-elevation plumbing. Under peak draw-off conditions, the twin pumps supply flow rates up to 160 L\/Min. It is ideally suited to multi-storey residential risers, hillside estates, and commercial hot-water ring mains.\u003c\/p\u003e\u003cp\u003eDynamic load sharing between the two pumps is orchestrated by differential pressure switches with a microprocessor control board. Under moderate demand, a single pump maintains target line pressure, while the second pump cuts in sequentially if heavy draw pulls pressure toward the lower setpoint. Automatic duty alternation swaps the starting sequence on every cycle to balance wear, and anti-cycling delay logic prevents rapid relay chatter.\u003c\/p\u003e\u003cp\u003eScale-resistant stainless steel AISI 304 suction and delivery headers form the backbone of the hydraulic assembly, keeping potable water clean and uncontaminated. Plumbers connect site piping to a 50 mm inlet header and a 40 mm discharge header, with dedicated isolation ball valves and non-return check valves fitted to each branch. An onboard system pressure gauge and a connection point for an external accumulator vessel round out the manifold layout.\u003c\/p\u003e\u003cp\u003eOperating entirely from a standard single-phase 230 V electrical supply and matching motor winding rating, this booster eliminates the need for three-phase power upgrades. Each 2-pole induction motor spins at approximately 2900 rpm (50 Hz), developing 1.1 kW (P2) of output power and drawing 7.4 A at full load. Built to IEC 60034 standards with Class F insulation, the drives provide long-lasting thermal endurance.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSix-Stage Pressure Boosting: Incorporates a 6-stage stainless steel hydraulic stack to generate exceptional discharge head for tall risers and high-friction pipework.\u003c\/li\u003e\n\u003cli\u003eSequential Cascade Control: Engages the second pump only when required by system demand and alternates lead duty via the microprocessor controller.\u003c\/li\u003e\n\u003cli\u003eSanitary Stainless Headers: Constructed with AISI 304 stainless steel suction and delivery manifolds to prevent internal rusting and preserve water quality.\u003c\/li\u003e\n\u003cli\u003eThermal Versatility: Handles chilled water and hot potable water loops across a broad operating temperature span of -15 °C to +110 °C.\u003c\/li\u003e\n\u003cli\u003ePlant Room Ingress Rating: Sealed to IP54 standards to protect motor windings and control circuitry against airborne dust and water splashes.\u003c\/li\u003e\n\u003cli\u003eFull Branch Serviceability: Combines individual shut-off ball valves and spring-loaded check valves so either pump can be isolated without shutting down the system.\u003c\/li\u003e\n\u003cli\u003eAnti-Cycling Switch Protection: Uses calibrated differential pressure switches with microprocessor timers to stop nuisance starting during minor pressure fluctuations.\u003c\/li\u003e\n\u003cli\u003eReady-to-Install Skid: Delivered factory assembled and hydrostatically tested on a unified frame, backed by 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 206 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 100 L galvanised diaphragm expansion tank\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":51423236194551,"sku":"BSM2F 2MXHLM 206","price":14305.5,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-bsm2f-2mxhlm-206-single-phase-2-x-1-1kw-fixed-speed-twin-pump-multistage-booster-system.png?v=1793070911","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-bsm2f-2mxhlm-206-single-phase-2-x-1-1kw-fixed-speed-twin-pump-multistage-booster-system","provider":"Foundation Pumps","version":"1.0","type":"link"}
