Three Grundfos CRNE 3-10 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 99752177.\u003c\/p\u003e\u003cp\u003eDelivering robust volume up to 270 L\/min through the stainless manifold, Line pressure is maintained with up to 96 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\u003eEngineered on a compact plant room skid, the assembly 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 7.11 A (3 x 2.37 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\u003eThe assembly is routinely deployed across hospital surgical wings, aged-care complexes and industrial process supply, providing quiet, reliable pressure boosting. 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\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\u003cli\u003eFactory assembled and wet-tested, the set arrives pre-configured for straightforward installation.\u003c\/li\u003e\n\u003cli\u003eSlow-speed duty and staged switching keep consumption down through low-demand hours.\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\u003eMaximum operating pressure of 10 bar with motors sealed to IP55.\u003c\/li\u003e\n\u003cli\u003eThe controller tracks the pressure setpoint with proportional deviation alerts before conditions become faults.\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\u003eThe system pairs three CRNE 3-10 pumps in parallel duty, controlled as a single coordinated system.\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\u003eMulti-Master redundancy means either pump can act as controller, with seamless changeover on fault.\u003c\/li\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\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\u003e3 x Grundfos CRNE 3-10 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":51425998995703,"sku":"99752177","price":28045.6,"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-3-10-three-phase-1-1kw-variable-speed-304ss-booster-pump-set-24l-tank.png?v=1793092768","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-hydro-multi-e-3-x-crne-3-10-three-phase-1-1kw-variable-speed-304ss-booster-pump-set-24l-tank","provider":"Foundation Pumps","version":"1.0","type":"link"}
