Driven by 1 Calpeda MXHL 403 horizontal multistage pump, the BS1F 1MXHL 403 booster assembly supplies generous flows up to 133.3 L\/Min. For vertical risers and pressurised distribution lines, the pump assembly can reach up to 30 m of head. It maintains steady line pressure when multiple high-flow outlets open simultaneously across low-to-medium rise facilities.\u003c\/p\u003e\u003cp\u003eReliable start-and-stop automation is achieved through calibrated differential pressure switches managed by an integrated microprocessor control board. Rather than relying on raw switch closures alone, the processor enforces intelligent delay intervals that eliminate hydraulic shock and frequent motor restarts. Integrated safety interlocks monitor operating status around the clock to guard against dry-run conditions and thermal overload.\u003c\/p\u003e\u003cp\u003eConstructed from corrosion-resistant stainless steel AISI 304 pipework, the manifold set features a 32 mm suction header and a 25 mm delivery header. Full-port isolation ball valves and a spring-check non-return valve allow straightforward pump isolation while preventing backflow depressurisation. Technicians can monitor output pressure via the mounted dial gauge and connect an external diaphragm vessel directly to the dedicated manifold port.\u003c\/p\u003e\u003cp\u003eTaking its primary feed from a three-phase 415 V mains circuit, the unit drives a heavy-duty motor built with a three-phase 230\/400 V winding rating. The 2-pole induction design rotates at approximately 2900 rpm (50 Hz) to produce 0.55 kW (P2) of output power while drawing 1.6 A under full load. Class F winding insulation and strict adherence to IEC 60034 motor standards ensure exceptional longevity.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHigh-Flow Impeller Geometry: Utilises a 3-stage stainless steel hydraulic assembly tuned for elevated volumetric flow delivery.\u003c\/li\u003e\n\u003cli\u003eMicroprocessor Assisted Switching: Refines differential pressure switch signals with electronic timers to stop rapid pump cycling.\u003c\/li\u003e\n\u003cli\u003eSanitary Stainless Manifolds: Uses AISI 304 stainless steel across headers and wetted parts to ensure clean, rust-free water transport.\u003c\/li\u003e\n\u003cli\u003eVersatile Temperature Range: Pumps chilled water or high-temperature hot water reliably from -15 °C to +110 °C.\u003c\/li\u003e\n\u003cli\u003eProtected Motor Housing: Safeguards electrical internals against dust ingress and water splashes with an IP54 ingress rating.\u003c\/li\u003e\n\u003cli\u003eIntegrated Shut-Off \u0026amp; Check Valves: Simplifies maintenance isolation and stops reverse flow spin when the pump is idle.\u003c\/li\u003e\n\u003cli\u003eDiaphragm Tank Take-Off: Includes a pre-threaded manifold port designed for connecting an external expansion vessel.\u003c\/li\u003e\n\u003cli\u003ePre-Wired Turnkey Skid: Ships fully assembled, wired, and factory verified to reduce on-site commissioning time.\u003c\/li\u003e\n\u003cli\u003eBacked by Calpeda Warranty: Includes a 24 Months warranty covering factory build quality and component reliability.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eWhat's Included\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e1 x Calpeda MXHL 403 horizontal multistage pump\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":51423231377655,"sku":"BS1F 1MXHL 403","price":7089.5,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-bs1f-1mxhl-403-three-phase-0-55kw-fixed-speed-single-pump-multistage-booster-system.png?v=1793070780","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-bs1f-1mxhl-403-three-phase-0-55kw-fixed-speed-single-pump-multistage-booster-system","provider":"Foundation Pumps","version":"1.0","type":"link"}
