One factory-tested package replaces a shelf of loose components; order part number 93320271 to put it on site.\u003c\/p\u003e\u003cp\u003eThis set provides up to 5111 L\/min of flow capacity. Variable-speed operation can develop up to 101 metres of head where required. 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\u003eThe three-pump package arrives as one base-mounted assembly with stainless steel manifolds, two 200 mm manifold connections, valves, sensors and a pressure gauge, plus a 24L diaphragm tank. Electrical supply is 3 x 380-415 V at 50 \/ 60 Hz with a rated current of 132 A. The motors have IP54 protection and the system is rated to 16 bar maximum pressure. Liquid-temperature suitability is 5°C to 60°C. Inlet pressure is rated to 16 bar.\u003c\/p\u003e\u003cp\u003eApplications include hotel plant rooms, aged-care complexes and high-rise apartments. The control flexibility suits clean-water boosting in new installations and upgrades.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eEach pump is driven by IE5 permanent magnet motors with frequency-controlled speed matching demand.\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\u003eAn integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.\u003c\/li\u003e\n\u003cli\u003eRated 22 kW (P2) on every main pump in the frame.\u003c\/li\u003e\n\u003cli\u003eFactory assembled and wet-tested, the set arrives pre-configured for straightforward installation.\u003c\/li\u003e\n\u003cli\u003eNo external controller required: Multi-Master redundancy lets either pump assume the controlling role.\u003c\/li\u003e\n\u003cli\u003eMaximum operating pressure of 16 bar with motors sealed to IP54.\u003c\/li\u003e\n\u003cli\u003eThe stainless steel manifold assembly is supplied with two 200 mm manifold connections.\u003c\/li\u003e\n\u003cli\u003eThe system protects its pumps against dry running if the incoming supply is lost.\u003c\/li\u003e\n\u003cli\u003ePower use precisely tracks demand, avoiding the waste of fixed-speed alternates.\u003c\/li\u003e\n\u003cli\u003eThree Grundfos CRE 64-3 vertical multistage pumps run in parallel on one common base frame.\u003c\/li\u003e\n\u003cli\u003eSetup and monitoring run through the Grundfos GO app rather than a panel visit.\u003c\/li\u003e\n\u003cli\u003eCascade logic brings pumps on-line and off-line against changing demand without manual intervention.\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 64-3 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":51383697015031,"sku":"93320271","price":121690.8,"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-64-3-2-three-phase-22kw-variable-speed-booster-pump-set-24l-tank.png?v=1792667445","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-hydro-multi-e-3-x-cre-64-3-2-three-phase-22kw-variable-speed-booster-pump-set-24l-tank","provider":"Foundation Pumps","version":"1.0","type":"link"}
