The package operates three Grundfos CRNE 10-2 vertical multistage pumps in parallel, automatically staging each unit as flow demand increases. Part number 99752279 provides the complete tested package in a single order line.\u003c\/p\u003e\u003cp\u003eProviding high volumetric performance up to 905 L\/min across peak hours, Multistage vertical hydraulics produce up to 29 metres of maximum head. Because every pump carries its own frequency converter and Multi-Master software elects the controlling pump itself, losing a control unit or pressure sensor means seamless handover rather than a shutdown.\u003c\/p\u003e\u003cp\u003eConstructed on a heavy-duty mounting frame, the assembly incorporates stainless steel manifolds, two 80 mm 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\u003eKey commercial installations regularly feature the set across high-rise apartments, hotel plant rooms and schools and universities for constant line 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\u003eEach main pump is rated 1.1 kW (P2), so per-pump draw scales down as speed follows demand.\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\u003eStainless steel manifolds provide two 80 mm manifold connections ready for plant pipework.\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\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\u003eIntegrated Grundfos GO compatibility supports configuration, logging and diagnostics from a smartphone.\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\u003eMaximum operating pressure of 10 bar with motors sealed to IP55.\u003c\/li\u003e\n\u003cli\u003eThree Grundfos CRNE 10-2 pumps share the boosting work in parallel.\u003c\/li\u003e\n\u003cli\u003eThe controller tracks the pressure setpoint with proportional deviation alerts before conditions become faults.\u003c\/li\u003e\n\u003cli\u003eAn integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.\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 10-2 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":51425999749367,"sku":"99752279","price":27033.6,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-hydro-multi-e-3-x-crne-10-2-single-phase-1-1kw-variable-speed-booster-pump-set-24l-tank.png?v=1793092727","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-hydro-multi-e-3-x-crne-10-2-single-phase-1-1kw-variable-speed-booster-pump-set-24l-tank","provider":"Foundation Pumps","version":"1.0","type":"link"}
