Product Overview
Multi-building retirement estate villages managing extensive ring mains operate the Hydro Multi-E 3 CRNE 10-10. Three Grundfos CRNE 10-10 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 99752298.
Delivering up to 905 L/min of continuous volumetric flow across the plant, Line pressure is maintained with up to 149 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.
Built on an integrated floor-mounted baseplate, the system brings together stainless steel pipework, two 80 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 Hz with combined rated current of 32.9 A (3 x 10.97 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.
The engineered booster set provides unshakeable water boosting across hospital surgical wings, aged-care complexes and industrial process supply, supporting tough plant duty. Variable-speed motor modulation makes the set a practical clean-water pressure-boosting solution for both new plant rooms and system upgrades.
FEATURES
- At P2 each main pump is 5.5 kW, covering the duty without oversizing the frame.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- Three Grundfos CRNE 10-10 vertical multistage pumps run in parallel on one common base frame.
- Variable speed comes from frequency converters matched to IE5 permanent magnet motors, keeping the booster set in its efficient range.
- Stainless steel manifolds provide two 80 mm manifold connections ready for plant pipework.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a smartphone.
- The system protects its pumps against dry running if the incoming supply is lost.
- Pump staging follows demand automatically: pumps enter at low speed as pressure drops, ramp to equal speed, and exit as flow fades.
- Energy draw matches the actual job because speed follows demand, not a fixed curve.
- Maximum operating pressure of 16 bar with motors sealed to IP55.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- The controller tracks the pressure setpoint with proportional deviation alerts before conditions become faults.
