Three Grundfos CRNE45-4-2 multistage pumps work in unison to eliminate pressure fluctuations during heavy usage. Part number 93368432 provides the complete tested package in a single order line.\u003c\/p\u003e\n\u003cp\u003eEngineered for zero-cavitation performance, overall pump discharge scales up to 3500 L\/min. Across vertical multi-storey plumbing risers, the package comfortably develops up to 133.1 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 robust mechanical package rests on a vibration-damped structural steel base. 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 132 A (3 x 44 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\u003eEngineered for winery operations, cellar door tasting rooms, and barrel wash areas. 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\u003eFactory-fitted 24L diaphragm pressure tank to suppress water hammer\u003c\/li\u003e\n\u003cli\u003ePeak volumetric clean water delivery flow up to 3500 L\/min\u003c\/li\u003e\n\u003cli\u003eCombined rated current draw of 132 A (3 x 44 A per pump)\u003c\/li\u003e\n\u003cli\u003eDual pressure transmitters providing continuous line monitoring and fault failover\u003c\/li\u003e\n\u003cli\u003eElectrical supply rating: 3 x 380-415 V at 50 \/ 60 Hz\u003c\/li\u003e\n\u003cli\u003ePre-plumbed with two 200 mm manifold connections and isolating non-return valves\u003c\/li\u003e\n\u003cli\u003eMaximum operating pressure rating of 16 bar for robust commercial duty\u003c\/li\u003e\n\u003cli\u003ePermissible liquid temperature range from 5°C to 60°C\u003c\/li\u003e\n\u003cli\u003eIndustrial IP55 dust and moisture ingress protection on all pump drives\u003c\/li\u003e\n\u003cli\u003eWetted components manufactured from high-grade Stainless Steel and 316-grade fittings\u003c\/li\u003e\n\u003cli\u003eIntegrated multi-pump array featuring three Grundfos CRNE45-4-2 multistage pumps\u003c\/li\u003e\n\u003cli\u003eMaximum vertical delivery head up to 133.1 metres\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 CRNE45-4-2 U2 A-A-I-I-D Factory-Tested Booster Skid\u003c\/li\u003e\n\u003cli\u003eThree x Grundfos CRNE45-4-2 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":51466803216631,"sku":"93368432","price":136710.2,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-hydro-multi-e-3-x-crne45-4-2-three-phase-22kw-variable-speed-booster-pump-set-24l-tank.png?v=1793172914","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-hydro-multi-e-3-x-crne45-4-2-three-phase-22kw-variable-speed-booster-pump-set-24l-tank","provider":"Foundation Pumps","version":"1.0","type":"link"}
