Two Grundfos CRNE 5-12 multistage pumps share the hydraulic load across a common skid, staging smoothly to match real-time draw. The complete booster system ships factory assembled and certified under part number 99752247.\u003c\/p\u003e\u003cp\u003ePeak line volume reaches up to 340 L\/min across active commercial branches. Line pressure is maintained with up to 120 metres of maximum delivery head. 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\u003ePre-plumbed on an industrial base chassis, the system features stainless steel pipework, two Rp 2 inch threaded 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 8.86 A (2 x 4.43 A per pump). Motors carry IP55 sealing with maximum pressure of 16 bar. Liquid-temperature suitability is 5°C to 60°C, and inlet pressure is rated to 16 bar.\u003c\/p\u003e\u003cp\u003ePlumbing contractors routinely install the set across hospital surgical wings, aged-care complexes and industrial process supply for straightforward plant hookup. 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\u003eIntegrated Grundfos GO compatibility supports configuration, logging and diagnostics from a smartphone.\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\u003eConstant pressure control holds the delivered pressure flat while proportional mode lets setpoints flex with demand.\u003c\/li\u003e\n\u003cli\u003eMaximum operating pressure of 16 bar with motors sealed to IP55.\u003c\/li\u003e\n\u003cli\u003eTwo Grundfos CRNE 5-12 vertical multistage pumps run in parallel on one common base 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\u003eRated 2.2 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\u003eDry-running protection is built into the control, protecting the pumps if the suction supply is interrupted.\u003c\/li\u003e\n\u003cli\u003ePower use precisely tracks demand, avoiding the waste of fixed-speed alternates.\u003c\/li\u003e\n\u003cli\u003eStainless steel manifolds provide two Rp 2 inch threaded manifold connections ready for plant pipework.\u003c\/li\u003e\n\u003cli\u003eAn integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.\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\u003e2 x Grundfos CRNE 5-12 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":51425984315639,"sku":"99752247","price":24998.6,"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-5-12-three-phase-2-2kw-variable-speed-304ss-booster-pump-set-24l-tank.png?v=1793092563","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-hydro-multi-e-2-x-crne-5-12-three-phase-2-2kw-variable-speed-304ss-booster-pump-set-24l-tank","provider":"Foundation Pumps","version":"1.0","type":"link"}
