Staged parallel operation between three CRE 45-1 pumps maintains consistent line pressure without erratic cycling. Quote part number 93320247 to have the entire pre-commissioned assembly delivered to site.\u003c\/p\u003e\u003cp\u003eVolumetric supply reaches up to 3500 L\/min to protect pipework pressure. Up to 38.6 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 a heavy-duty structural frame, the package features stainless steel pipework, two 200 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 40.9 A (3 x 13.63 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\u003eClean-water distribution duties cover food production facilities, logistics distribution hubs and aquatic sports centres, where automated multi-pump staging is required. 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 IP54.\u003c\/li\u003e\n\u003cli\u003eRated 5.5 kW (P2) on every main pump in the frame.\u003c\/li\u003e\n\u003cli\u003eAn integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.\u003c\/li\u003e\n\u003cli\u003eThe controller tracks the pressure setpoint with proportional deviation alerts before conditions become faults.\u003c\/li\u003e\n\u003cli\u003eEnergy draw matches the actual job because speed follows demand, not a fixed curve.\u003c\/li\u003e\n\u003cli\u003eStainless steel manifolds provide two 200 mm manifold connections ready for plant pipework.\u003c\/li\u003e\n\u003cli\u003eIntegrated Grundfos GO compatibility supports configuration, logging and diagnostics from a smartphone.\u003c\/li\u003e\n\u003cli\u003eThe system pairs three CRE 45-1 pumps in parallel duty, controlled as a single coordinated system.\u003c\/li\u003e\n\u003cli\u003eFactory assembled and wet-tested, the set arrives pre-configured for straightforward installation.\u003c\/li\u003e\n\u003cli\u003eVariable speed comes from frequency converters matched to IE5 permanent magnet motors, keeping the booster set in its efficient range.\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\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\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eWhat's Included\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e3 x Grundfos CRE 45-1 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":51425992769783,"sku":"93320247","price":59911.5,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-hydro-multi-e-3-x-cre-45-1-three-phase-5-5kw-variable-speed-booster-pump-set-24l-tank.png?v=1793092685","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-hydro-multi-e-3-x-cre-45-1-three-phase-5-5kw-variable-speed-booster-pump-set-24l-tank","provider":"Foundation Pumps","version":"1.0","type":"link"}
