The three-pump parallel layout shares duty evenly across the CRNE 5-7 wet ends, preserving steady pressure during morning spikes. Quote part number 99752216 to have the entire pre-commissioned assembly delivered to site.\u003c\/p\u003e\u003cp\u003eThe booster handles commercial flow volumes up to 510 L\/min with ease. Up to 69 metres of shut-off head is generated to overcome vertical riser friction. There is no separate central controller to purchase: Multi-Master control resides within the pumps, either unit can assume the controlling role, and a fault is handed over cleanly without interrupting supply.\u003c\/p\u003e\u003cp\u003eFactory aligned on an engineered mounting skid, the assembly incorporates 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 1 x 200-240 V supply at 50 \/ 60 Hz with combined rated current of 19.4 A (3 x 6.47 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\u003eThe set is an ideal choice for hospital surgical wings, aged-care complexes and industrial process supply, where fluctuating tenancy water demands occur. 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\u003eMaximum operating pressure of 10 bar with motors sealed to IP55.\u003c\/li\u003e\n\u003cli\u003eStainless steel manifolds provide two Rp 2 inch threaded manifold connections ready for plant pipework.\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\u003eCascade logic brings pumps on-line and off-line against changing demand without manual intervention.\u003c\/li\u003e\n\u003cli\u003eFactory assembled and wet-tested, the set arrives pre-configured for straightforward installation.\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\u003eEnergy draw matches the actual job because speed follows demand, not a fixed curve.\u003c\/li\u003e\n\u003cli\u003eEach pump is driven by IE5 permanent magnet motors with frequency-controlled speed matching demand.\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\u003eIntegrated Grundfos GO compatibility supports configuration, logging and diagnostics from a smartphone.\u003c\/li\u003e\n\u003cli\u003eAn integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.\u003c\/li\u003e\n\u003cli\u003eThree Grundfos CRNE 5-7 vertical multistage pumps run in parallel on one common base frame.\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\u003e3 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":51425999192311,"sku":"99752216","price":26270.2,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-hydro-multi-e-3-x-crne-5-7-single-phase-1-1kw-variable-speed-304ss-booster-pump-set-24l-tank.png?v=1793092852","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-hydro-multi-e-3-x-crne-5-7-single-phase-1-1kw-variable-speed-304ss-booster-pump-set-24l-tank","provider":"Foundation Pumps","version":"1.0","type":"link"}
