Product Overview
Where school blocks and council facilities fed by long, pressure-hungry reticulation are served from a single booster, the Hydro Multi-E 2 CRNE 10-5 holds pressure steady as two CRNE 10-5 pumps respond to changing flow. The complete system ships factory assembled and tested under part number 99752289.
The system supports flow rates up to 476 L/min. It can develop up to 71 metres of head for dependable pressure boosting. 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.
For installation, the booster is supplied pre-assembled with stainless steel manifolds, two 50 mm manifold connections, isolation valves, non-return valves, pressure sensors and a gauge, plus a 24L diaphragm tank. It is designed for 3 x 380-415 V power at 50 / 60 Hz with a rated current of 8.86 A, with IP55 motor protection and a 10 bar maximum system pressure. Liquid-temperature suitability is 5°C to 60°C. Inlet pressure is rated to 10 bar.
Expect it on mixed-use commercial buildings and aged-care complexes sites, plus schools and universities duties. It provides clean-water pressure boosting for both new plant rooms and refits.
Features
- Stainless steel manifolds provide two 50 mm manifold connections ready for pipework.
- Frequency converters on the motors pair with IE5 permanent magnet motors for efficient part-load operation.
- No external controller required: Multi-Master redundancy lets either pump assume the controlling role.
- At P2 each main pump is 2.2 kW, covering the duty without oversizing the frame.
- Power use precisely tracks demand, avoiding the waste of fixed-speed alternates.
- Cascade logic brings pumps on-line and off-line against changing demand without manual intervention.
- Setup and monitoring run through the Grundfos GO app rather than a panel visit.
- Two Grundfos CRNE 10-5 vertical multistage pumps run in parallel on one common base frame.
- The system protects its pumps against dry running if the incoming supply is lost.
- Rated for 10 bar system pressure; motors carry IP55 protection.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- The package is wet-tested and pre-configured, requiring only pipework and power on site.
- Both constant-pressure and proportional-pressure modes are available, so plant rooms can tune response to pipework.
