Featuring three horizontal multistage Calpeda MXHL 404 pumps mounted on a unified baseplate, this system delivers flow rates up to 399.9 L\/Min. Where high-pressure boosting is needed, the hydraulic stages can produce up to 40.5 m of head. AISI 304 stainless steel construction across the pump casings, diffusers, and impellers ensures lasting durability in potable water and hot-water boosting roles.\u003c\/p\u003e\u003cp\u003eProportional speed modulation is handled directly at the motor level by three integrated I-MAT frequency converters. Instead of harsh stop-start cycling, the inverters modulate pump speed smoothly to hold target line pressure while tracking energy metrics in real time. As fixture demand increases, additional pumps cascade into service automatically and alternate lead duty across consecutive cycles, supported by built-in electronic protections against dry running, overcurrent, and supply voltage faults.\u003c\/p\u003e\u003cp\u003eInlet and outlet flows are routed through heavy-gauge AISI 304 stainless steel manifolds sized with a 65 mm inlet and a 50 mm outlet. Each of the three pump branches is equipped with isolation ball valves and non-return check valves, preventing reverse flow through standby units and allowing maintenance without full plant shutdown. On the delivery header, installers will find a factory-fitted pressure gauge and a dedicated connection point for an external diaphragm tank.\u003c\/p\u003e\u003cp\u003eReceiving power from a convenient single-phase 230 V power supply, the onboard frequency converters deliver regulated three-phase 230\/400 V output to the motor windings. Each 2-pole induction motor provides 0.75 kW (P2) of mechanical power and draws 2 A while turning at approximately 2900 rpm (50 Hz). Compliant with IEC 60034 engineering standards and built with Class F winding insulation, the drive train ensures dependable thermal performance under continuous load.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eStainless 4-Stage Hydraulics: Close-coupled 4-stage AISI 304 stainless steel impellers provide balanced flow and pressure for medium-rise buildings.\u003c\/li\u003e\n\u003cli\u003eOnboard I-MAT Frequency Drives: Individual inverters mounted on each pump adjust speed dynamically to maintain constant outlet pressure.\u003c\/li\u003e\n\u003cli\u003eThree-Pump Cascade Control: Automatic staging and duty rotation spread mechanical wear evenly and provide N+1 operational redundancy.\u003c\/li\u003e\n\u003cli\u003eCorrosion-Free Headers: AISI 304 stainless steel suction and delivery manifolds safeguard potable water quality and structural integrity.\u003c\/li\u003e\n\u003cli\u003eIsolated Maintenance Design: Branch ball valves and non-return valves allow any single pump to be serviced while the system stays active.\u003c\/li\u003e\n\u003cli\u003eSealed Motor Housing: Constructed with IP54 ingress protection and Class F insulation to withstand humid plant-room environments.\u003c\/li\u003e\n\u003cli\u003eWide Liquid Temperature Range: Suitable for cold water boosting and hot water circulation from -15 °C to +110 °C.\u003c\/li\u003e\n\u003cli\u003eVessel Port Included: Pre-configured manifold connection point simplifies the addition of an external pressure accumulation tank.\u003c\/li\u003e\n\u003cli\u003eFactory Tested Quality: Supplied fully assembled and supported 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\u003e3 x Calpeda MXHL 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\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":51423240552695,"sku":"BSM3V 3MXHL 404-EMT","price":21011.1,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-bsm3v-3mxhl-404-emt-3-x-0-75kw-variable-speed-3-pump-multistage-booster-set-easymat-converter.png?v=1793071077","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-bsm3v-3mxhl-404-emt-3-x-0-75kw-variable-speed-3-pump-multistage-booster-set-easymat-converter","provider":"Foundation Pumps","version":"1.0","type":"link"}
