Three Grundfos CRNE45-2-2 multistage pumps work in unison to eliminate pressure fluctuations during heavy usage. Part number 93368426 provides the complete tested package in a single order line.\u003c\/p\u003e\n\u003cp\u003eHydraulic testing demonstrates this booster arrangement provides peak discharge up to 3500 L\/min. Across vertical multi-storey plumbing risers, the package comfortably develops up to 59.8 metres of head. Multi-Master autonomous inverter technology enables each pump to take lead control dynamically, providing complete hardware redundancy without requiring a separate central control cabinet.\u003c\/p\u003e\n\u003cp\u003eThe package features an industrial-grade mounting skid designed for easy rigging. The set is fully pre-plumbed with two 200 mm manifold connections, dedicated isolation valves, and integrated non-return valves on each discharge line. It connects to a 3 x 380-415 V supply at 50 \/ 60 Hz with combined rated current of 77.4 A (3 x 25.8 A per pump). A 24L diaphragm pressure tank absorbs initial draw-offs and line hammer, while IP55 enclosure protection and a 16 bar pressure rating ensure long-term mechanical reliability. Liquid-temperature suitability is 5°C to 60°C for all standard clean water booster duties.\u003c\/p\u003e\n\u003cp\u003eTailored for private healthcare clinics, dental centres, and specialist outpatient suites. Integrating variable speed electronic control eliminates water hammer, extends mechanical life, and lowers lifecycle energy consumption compared to fixed-speed boosting systems.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eElectrical supply rating: 3 x 380-415 V at 50 \/ 60 Hz\u003c\/li\u003e\n\u003cli\u003eIndustrial IP55 dust and moisture ingress protection on all pump drives\u003c\/li\u003e\n\u003cli\u003ePermissible liquid temperature range from 5°C to 60°C\u003c\/li\u003e\n\u003cli\u003eIntegrated multi-pump array featuring three Grundfos CRNE45-2-2 multistage pumps\u003c\/li\u003e\n\u003cli\u003eDual pressure transmitters providing continuous line monitoring and fault failover\u003c\/li\u003e\n\u003cli\u003ePeak volumetric clean water delivery flow up to 3500 L\/min\u003c\/li\u003e\n\u003cli\u003eMaximum operating pressure rating of 16 bar for robust commercial duty\u003c\/li\u003e\n\u003cli\u003ePre-plumbed with two 200 mm manifold connections and isolating non-return valves\u003c\/li\u003e\n\u003cli\u003eWetted components manufactured from high-grade Stainless Steel and 316-grade fittings\u003c\/li\u003e\n\u003cli\u003eCombined rated current draw of 77.4 A (3 x 25.8 A per pump)\u003c\/li\u003e\n\u003cli\u003eMaximum vertical delivery head up to 59.8 metres\u003c\/li\u003e\n\u003cli\u003eFactory-fitted 24L diaphragm pressure tank to suppress water hammer\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's Included\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eGrundfos Hydro Multi-E 3 CRNE45-2-2 U2 A-A-I-I-DU Factory-Tested Booster Skid\u003c\/li\u003e\n\u003cli\u003eThree x Grundfos CRNE45-2-2 Multistage Pumps with Integrated Frequency Converters\u003c\/li\u003e\n\u003cli\u003eIntegrated Multi-Master Autonomous Inverter Drive System\u003c\/li\u003e\n\u003cli\u003e1 x Factory-Mounted 24L Diaphragm Pressure Tank\u003c\/li\u003e\n\u003cli\u003eSuction and Discharge Manifolds (two 200 mm manifold connections)\u003c\/li\u003e\n\u003cli\u003eIndividual Pump Isolation Valves and Spring-Loaded Non-Return Valves\u003c\/li\u003e\n\u003cli\u003eDual Factory-Calibrated Pressure Transmitters\u003c\/li\u003e\n\u003cli\u003eHeavy-Duty Structural Steel Mounting Baseplate\u003c\/li\u003e\n\u003cli\u003eComprehensive Installation and Operating Documentation\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":51466780639479,"sku":"93368426","price":80674.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-hydro-multi-e-3-x-crne45-2-2-three-phase-7-5kw-variable-speed-booster-pump-set-24l-tank.png?v=1793172914","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-hydro-multi-e-3-x-crne45-2-2-three-phase-7-5kw-variable-speed-booster-pump-set-24l-tank","provider":"Foundation Pumps","version":"1.0","type":"link"}
