Configured with three CRE 45-1-1 vertical pumps in parallel, the booster dynamically matches motor speed to immediate water requirements. Part number 93320245 provides the complete tested package in a single order line.\u003c\/p\u003e\u003cp\u003eThe booster set effortlessly supplies up to 3500 L\/min during peak trading. Multistage vertical hydraulics produce up to 31 metres of maximum head. 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\u003eAssembled on an industrial floor-mount skid, the system brings together stainless steel manifolds, 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 29.9 A (3 x 9.97 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\u003eFrequently commissioned across facilities including mixed-use commercial buildings, corporate office towers and shopping centres, the system operates unattended. 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\u003eThe system pairs three CRE 45-1-1 pumps in parallel duty, controlled as a single coordinated system.\u003c\/li\u003e\n\u003cli\u003eSlow-speed duty and staged switching keep consumption down through low-demand hours.\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\u003eFactory assembled and wet-tested, the set arrives pre-configured for straightforward installation.\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 4 kW, covering the duty without oversizing the frame.\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\u003eStainless steel manifolds provide two 200 mm manifold connections ready for plant pipework.\u003c\/li\u003e\n\u003cli\u003eThe system protects its pumps against dry running if the incoming supply is lost.\u003c\/li\u003e\n\u003cli\u003eAn integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.\u003c\/li\u003e\n\u003cli\u003eMaximum operating pressure of 10 bar with motors sealed to IP54.\u003c\/li\u003e\n\u003cli\u003eThe controller tracks the pressure setpoint with proportional deviation alerts before conditions become faults.\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 45-1-1 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":51425992409335,"sku":"93320245","price":53169.6,"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-45-1-1-three-phase-4kw-variable-speed-booster-pump-set-24l-tank.png?v=1793092685","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-hydro-multi-e-3-x-cre-45-1-1-three-phase-4kw-variable-speed-booster-pump-set-24l-tank","provider":"Foundation Pumps","version":"1.0","type":"link"}
