Configured with two CRNE 64-2-1 vertical pumps in parallel, the booster dynamically matches motor speed to immediate water requirements. Everything is ordered under the single manufacturer part number 93368439.\u003c\/p\u003e\u003cp\u003eAt maximum operating frequency, the package yields up to 3400 L\/min. The vertical stage assembly can build up to 74 metres of head for steep elevations. Integrated Multi-Master intelligence coordinates the pumps without requiring an external control panel, ensuring automatic role swapping and uninterrupted pressure stabilization.\u003c\/p\u003e\u003cp\u003eMounted on a vibration-dampened base skid, the booster incorporates 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 39.2 A (2 x 19.6 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\u003eRoutine plant room duty sits with mixed-use commercial buildings, corporate office towers and shopping centres, delivering seamless pressure regulation across shifts. 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\u003eMaximum operating pressure of 10 bar with motors sealed to IP54.\u003c\/li\u003e\n\u003cli\u003eFactory assembled and wet-tested, the set arrives pre-configured for straightforward installation.\u003c\/li\u003e\n\u003cli\u003eTwo Grundfos CRNE 64-2-1 vertical multistage pumps run in parallel on one common base frame.\u003c\/li\u003e\n\u003cli\u003eIntegrated Grundfos GO compatibility supports configuration, logging and diagnostics from a smartphone.\u003c\/li\u003e\n\u003cli\u003ePumps are cut in and out according to demand, every running unit turning at the same speed to hold the pressure set point.\u003c\/li\u003e\n\u003cli\u003eThe system protects its pumps against dry running if the incoming supply is lost.\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\u003eAn integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.\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\u003eAt P2 each main pump is 18.5 kW, covering the duty without oversizing the frame.\u003c\/li\u003e\n\u003cli\u003eConstant pressure control holds the delivered pressure flat while proportional mode lets setpoints flex with demand.\u003c\/li\u003e\n\u003cli\u003eEnergy draw matches the actual job because speed follows demand, not a fixed curve.\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 64-2-1 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":51425968980215,"sku":"93368439","price":83567.0,"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-64-2-1-three-phase-18-5kw-variable-speed-booster-pump-set-24l-tank.png?v=1793092602","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-hydro-multi-e-2-x-crne-64-2-1-three-phase-18-5kw-variable-speed-booster-pump-set-24l-tank","provider":"Foundation Pumps","version":"1.0","type":"link"}
