Three Grundfos CRNE 20-1 multistage pumps work in unison to eliminate pressure fluctuations during heavy usage. Part number 99752347 provides the complete tested package in a single order line.\u003c\/p\u003e\n\u003cp\u003eUnder peak simultaneous facility draw, the skid maintains volumetric flow up to 1750 L\/min. Across vertical multi-storey plumbing risers, the package comfortably develops up to 20 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 mechanical package is anchored to an ultra-sturdy, laser-cut mounting baseplate. The set is fully pre-plumbed with two 100 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 9.3 A (3 x 3.1 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\u003eA standard choice for regional council amenities, public libraries, and civic buildings. 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\u003eMaximum operating pressure rating of 16 bar for robust commercial duty\u003c\/li\u003e\n\u003cli\u003eElectrical supply rating: 3 x 380-415 V at 50 \/ 60 Hz\u003c\/li\u003e\n\u003cli\u003eMaximum vertical delivery head up to 20 metres\u003c\/li\u003e\n\u003cli\u003eIndustrial IP55 dust and moisture ingress protection on all pump drives\u003c\/li\u003e\n\u003cli\u003eFactory-fitted 24L diaphragm pressure tank to suppress water hammer\u003c\/li\u003e\n\u003cli\u003eCombined rated current draw of 9.3 A (3 x 3.1 A per pump)\u003c\/li\u003e\n\u003cli\u003ePre-plumbed with two 100 mm manifold connections and isolating non-return valves\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 CRNE 20-1 multistage pumps\u003c\/li\u003e\n\u003cli\u003ePeak volumetric clean water delivery flow up to 1750 L\/min\u003c\/li\u003e\n\u003cli\u003eWetted components manufactured from high-grade Stainless Steel and 316-grade fittings\u003c\/li\u003e\n\u003cli\u003eDual pressure transmitters providing continuous line monitoring and fault failover\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 CRNE 20-1 U2 A-A-I-I-DU Factory-Tested Booster Skid\u003c\/li\u003e\n\u003cli\u003eThree x Grundfos CRNE 20-1 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 100 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":51466712449271,"sku":"99752347","price":34621.4,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-hydro-multi-e-3-x-crne-20-1-three-phase-1-5kw-variable-speed-booster-pump-set-24l-tank.png?v=1793172914","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-hydro-multi-e-3-x-crne-20-1-three-phase-1-5kw-variable-speed-booster-pump-set-24l-tank","provider":"Foundation Pumps","version":"1.0","type":"link"}
