Operating two CRNE 5-7 pumps in parallel duty, the booster automatically cuts pumps in and out to track line velocity. Quote part number 99752221 to have the entire pre-commissioned assembly delivered to site.\u003c\/p\u003e\u003cp\u003eAt peak operating velocity, the system flows up to 340 L\/min. Up to 69 metres of shut-off head is generated to overcome vertical riser friction. Advanced Multi-Master firmware shares operating duties directly between pump heads, providing immediate fail-safe handover if an individual drive is isolated.\u003c\/p\u003e\u003cp\u003eEngineered on an integrated floor skid, the booster pairs stainless steel pipework, two Rp 2 inch threaded 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 4.74 A (2 x 2.37 A per pump). Motors carry IP55 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\u003eInstitutional applications cover facilities like food production facilities, logistics distribution hubs and aquatic sports centres, where uninterrupted water is critical. 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 Rp 2 inch threaded manifold connections ready for plant pipework.\u003c\/li\u003e\n\u003cli\u003eDry-running protection is built into the control, protecting the pumps if the suction supply is interrupted.\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\u003eMaximum operating pressure of 10 bar with motors sealed to IP55.\u003c\/li\u003e\n\u003cli\u003eAn integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.\u003c\/li\u003e\n\u003cli\u003eFactory assembled and wet-tested, the set arrives pre-configured for straightforward installation.\u003c\/li\u003e\n\u003cli\u003eThe system pairs two CRNE 5-7 pumps in parallel duty, controlled as a single coordinated system.\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\u003cli\u003ePower use precisely tracks demand, avoiding the waste of fixed-speed alternates.\u003c\/li\u003e\n\u003cli\u003eIntegrated Grundfos GO compatibility supports configuration, logging and diagnostics from a smartphone.\u003c\/li\u003e\n\u003cli\u003eAt P2 each main pump is 1.1 kW, covering the duty without oversizing the frame.\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\u003eMulti-Master redundancy means either pump can act as controller, with seamless changeover on fault.\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 5-7 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":51425983365367,"sku":"99752221","price":20747.1,"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-5-7-three-phase-1-1kw-variable-speed-304ss-booster-pump-set-24l-tank.png?v=1793092602","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-hydro-multi-e-2-x-crne-5-7-three-phase-1-1kw-variable-speed-304ss-booster-pump-set-24l-tank","provider":"Foundation Pumps","version":"1.0","type":"link"}
