Integrated variable-speed drives coordinate the two CRNE 45-1-1 pumps in parallel, seamlessly ramping output as fixtures open. Specify part number 93368419 and the complete factory-tested package arrives ready for connection.\u003c\/p\u003e\u003cp\u003eVolumetric capacity easily scales to 2333 L\/min during heavy morning use. To pressurise elevated upper levels, the pumps develop up to 31 metres of head. Because every pump carries its own frequency converter and Multi-Master software elects the controlling pump itself, losing a control unit or pressure sensor means seamless handover rather than a shutdown.\u003c\/p\u003e\u003cp\u003eEngineered as a plug-and-play plant room skid, the assembly features stainless steel manifolds, two 150 mm manifold connections, isolation and non-return valves, pressure sensors, plus a 24L diaphragm tank. It connects to a 3 x 380-415 V supply at 50 \/ 60 Hz with combined rated current of 27.2 A (2 x 13.6 A per pump). Motors carry IP54 sealing with maximum pressure of 10 bar. Liquid-temperature suitability is 5°C to 60°C, and inlet pressure is rated to 10 bar.\u003c\/p\u003e\u003cp\u003eSuited to multi-fixture commercial layouts like high-rise apartments, hotel plant rooms and schools and universities, the system ensures uniform pressure. Variable-speed motor modulation makes the set a practical clean-water pressure-boosting solution for both new plant rooms and system upgrades.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eStainless steel manifolds provide two 150 mm manifold connections ready for plant pipework.\u003c\/li\u003e\n\u003cli\u003eTwo Grundfos CRNE 45-1-1 vertical multistage pumps run in parallel on one common base frame.\u003c\/li\u003e\n\u003cli\u003eSlow-speed duty and staged switching keep consumption down through low-demand hours.\u003c\/li\u003e\n\u003cli\u003eFrequency converters on the motors pair with IE5 permanent magnet motors for efficient part-load operation.\u003c\/li\u003e\n\u003cli\u003eIntegrated Grundfos GO compatibility supports configuration, logging and diagnostics from a smartphone.\u003c\/li\u003e\n\u003cli\u003eFactory assembled and wet-tested, the set arrives pre-configured for straightforward installation.\u003c\/li\u003e\n\u003cli\u003eCascade logic brings pumps on-line and off-line against changing demand without manual intervention.\u003c\/li\u003e\n\u003cli\u003eThe system protects its pumps against dry running if the incoming supply is lost.\u003c\/li\u003e\n\u003cli\u003eAn integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.\u003c\/li\u003e\n\u003cli\u003eRated 4 kW (P2) on every main pump in the frame.\u003c\/li\u003e\n\u003cli\u003eMulti-Master redundancy means either pump can act as controller, with seamless changeover on fault.\u003c\/li\u003e\n\u003cli\u003eMaximum operating pressure of 10 bar with motors sealed to IP54.\u003c\/li\u003e\n\u003cli\u003eBoth constant-pressure and proportional-pressure modes are available, so plant rooms can tune response to pipework.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eWhat's Included\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e2 x Grundfos CRNE 45-1-1 vertical multistage pumps\u003c\/li\u003e\n\u003cli\u003eIE5 permanent magnet motors with integrated frequency converters\u003c\/li\u003e\n\u003cli\u003eStainless steel suction manifold\u003c\/li\u003e\n\u003cli\u003eStainless steel discharge manifold\u003c\/li\u003e\n\u003cli\u003eNon-return valves\u003c\/li\u003e\n\u003cli\u003eIsolation valves\u003c\/li\u003e\n\u003cli\u003ePressure sensors\/transmitters\u003c\/li\u003e\n\u003cli\u003ePressure gauge\u003c\/li\u003e\n\u003cli\u003e24L diaphragm pressure tank\u003c\/li\u003e\n\u003cli\u003eFactory assembled and tested booster system\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":51425973829879,"sku":"93368419","price":39397.6,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-hydro-multi-e-2-x-crne-45-1-1-three-phase-4kw-variable-speed-304ss-booster-pump-set-24l-tank.png?v=1793092520","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-hydro-multi-e-2-x-crne-45-1-1-three-phase-4kw-variable-speed-304ss-booster-pump-set-24l-tank","provider":"Foundation Pumps","version":"1.0","type":"link"}
