Operating two CRNE 45-2 pumps in parallel duty, the booster automatically cuts pumps in and out to track line velocity. Ordering part number 93368421 puts the fully tested booster skid directly onto the plant room floor.\u003c\/p\u003e\u003cp\u003eThe pump system handles demand peaks up to 2333 L\/min without pressure loss. Up to 75 metres of delivery head is available to keep upper-floor fixtures pressurised. 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\u003eMechanically aligned on a heavy-gauge base frame, the package features stainless steel pipework, two 150 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 27.2 A (2 x 13.6 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\u003ePrimary plant room installations include food production facilities, logistics distribution hubs and aquatic sports centres, providing energy-efficient water pressure. 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 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\u003eCascade logic brings pumps on-line and off-line against changing demand without manual intervention.\u003c\/li\u003e\n\u003cli\u003eMaximum operating pressure of 10 bar with motors sealed to IP54.\u003c\/li\u003e\n\u003cli\u003eConstant pressure control holds the delivered pressure flat while proportional mode lets setpoints flex with demand.\u003c\/li\u003e\n\u003cli\u003eFactory assembled and wet-tested, the set arrives pre-configured for straightforward installation.\u003c\/li\u003e\n\u003cli\u003eTwo Grundfos CRNE 45-2 pumps share the boosting work in parallel.\u003c\/li\u003e\n\u003cli\u003eStainless steel manifolds provide two 150 mm manifold connections ready for plant pipework.\u003c\/li\u003e\n\u003cli\u003eSlow-speed duty and staged switching keep consumption down through low-demand hours.\u003c\/li\u003e\n\u003cli\u003eEach main pump is rated 11 kW (P2), so per-pump draw scales down as speed follows demand.\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\u003eAn integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.\u003c\/li\u003e\n\u003cli\u003eIntegrated Grundfos GO compatibility supports configuration, logging and diagnostics from a smartphone.\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 45-2 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":51425974485239,"sku":"93368421","price":66118.8,"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-45-2-three-phase-11kw-variable-speed-304ss-booster-pump-set-24l-tank.png?v=1793092563","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-hydro-multi-e-2-x-crne-45-2-three-phase-11kw-variable-speed-304ss-booster-pump-set-24l-tank","provider":"Foundation Pumps","version":"1.0","type":"link"}
