Three horizontal multistage Calpeda MXHL 403 pumps work together on a common frame to supply up to 399.9 L\/Min of flow. The multistage impeller stack can develop up to 30 m of head to overcome static building height. With all hydraulic chambers and impellers formed from AISI 304 stainless steel, the package ensures hygienic handling of both potable cold water and heated circulation fluids.\u003c\/p\u003e\u003cp\u003eEach pump is driven by its own motor-mounted I-MAT frequency converter, creating a responsive variable-speed boosting plant. By tracking downstream line pressure continuously, the inverters adjust rotational speed to maintain a steady pressure setpoint regardless of how many taps or valves are open. Automatic cascade staging brings lag pumps online smoothly as demand grows, while periodic duty alternation balances operating hours and onboard safeties guard against dry running or electrical surges.\u003c\/p\u003e\u003cp\u003eManifold architecture centres on corrosion-proof AISI 304 stainless steel headers featuring a 65 mm suction inlet and a 50 mm delivery outlet. Individual isolation ball valves and non-return check valves are fitted to all three branches so any single pump can be isolated for maintenance without cutting water supply to the premises. The discharge manifold also incorporates an easy-to-read pressure gauge and a pre-tapped connection port for an external expansion vessel.\u003c\/p\u003e\u003cp\u003eIncoming power is supplied via a standard single-phase 230 V circuit, which the integrated I-MAT drives invert to energize the three-phase 230\/400 V motor windings. Every pump uses a 2-pole induction motor rated at 0.55 kW (P2) that draws 1.6 A at a nominal speed of 2900 rpm (50 Hz). Constructed to IEC 60034 standards with Class F insulation, the drive assemblies offer low-noise, energy-conscious operation across prolonged duty cycles.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eEfficient 3-Stage Impeller Stack: AISI 304 stainless steel 3-stage hydraulics deliver high flow capacity with smooth, quiet pressure build-up.\u003c\/li\u003e\n\u003cli\u003eIntegrated I-MAT Inverters: Pump-mounted variable frequency drives regulate speed accurately to eliminate water hammer and pressure swings.\u003c\/li\u003e\n\u003cli\u003eTriplex Duty Alternation: Intelligent staging rotates lead and standby roles across all three units to extend seal and bearing life.\u003c\/li\u003e\n\u003cli\u003eStainless Steel Pipework: Fabricated AISI 304 suction and delivery headers protect water purity and resist external plant-room corrosion.\u003c\/li\u003e\n\u003cli\u003eFull Branch Valving: Dedicated ball valves and non-return valves on every pump leg prevent backflow and simplify in-situ servicing.\u003c\/li\u003e\n\u003cli\u003eProtected Motor Enclosure: IP54 ingress protection paired with Class F thermal insulation shields motor internals from dust and moisture.\u003c\/li\u003e\n\u003cli\u003eHot \u0026amp; Cold Fluid Compatibility: Rated for continuous operation with clean liquids between -15 °C to +110 °C.\u003c\/li\u003e\n\u003cli\u003eExternal Vessel Tapping: Includes a manifold port ready to accept an external diaphragm tank for buffering small draw-offs.\u003c\/li\u003e\n\u003cli\u003eTwo-Year Peace of Mind: Backed by a 24 Months manufacturer warranty on the complete factory-tested skid.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eWhat's Included\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e3 x Calpeda MXHL 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\u003eIntegrated I-MAT frequency converters mounted on each pump\u003c\/li\u003e\n\u003cli\u003eSystem pressure gauge\u003c\/li\u003e\n\u003cli\u003eFactory assembled and tested boosting plant\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":51423240519927,"sku":"BSM3V 3MXHL 403-EMT","price":20650.3,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-bsm3v-3mxhl-403-emt-3-x-0-55kw-variable-speed-3-pump-multistage-booster-set-easymat-converter.png?v=1793071075","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-bsm3v-3mxhl-403-emt-3-x-0-55kw-variable-speed-3-pump-multistage-booster-set-easymat-converter","provider":"Foundation Pumps","version":"1.0","type":"link"}
