Product Overview
High-occupancy residential hostels balancing shared kitchen and bathroom lines choose the Hydro Multi-E 3 CRNE 10-2. Staged parallel operation between three CRNE 10-2 pumps maintains consistent line pressure without erratic cycling. The complete booster system ships factory assembled and certified under part number 99752277.
Total system throughput expands up to 905 L/min during maximum operation. Line pressure is maintained with up to 29 metres of maximum delivery head. Advanced Multi-Master firmware shares operating duties directly between pump heads, providing immediate fail-safe handover if an individual drive is isolated.
Factory built on an anti-vibration channel, the booster combines 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 / 60 Hz with combined rated current of 5.55 A (3 x 1.85 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.
The package serves commercial facilities like food production facilities, logistics distribution hubs and aquatic sports centres, where sudden fixture rushes are common. Variable-speed motor modulation makes the set a practical clean-water pressure-boosting solution for both new plant rooms and system upgrades.
FEATURES
- The controller tracks the pressure setpoint with proportional deviation alerts before conditions become faults.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a smartphone.
- Stainless steel manifolds provide two 80 mm manifold connections ready for plant pipework.
- The system protects its pumps against dry running if the incoming supply is lost.
- At P2 each main pump is 0.75 kW, covering the duty without oversizing the frame.
- Energy draw matches the actual job because speed follows demand, not a fixed curve.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.
- The system pairs three CRNE 10-2 pumps in parallel duty, controlled as a single coordinated system.
- Pumps are cut in and out according to demand, every running unit turning at the same speed to hold the pressure set point.
- Frequency converters on the motors pair with IE5 permanent magnet motors for efficient part-load operation.
- Maximum operating pressure of 10 bar with motors sealed to IP55.
