Product Overview
Wholesale produce market pavilions running morning wash hoses install the Hydro Multi-E 3 CRNE 10-6. Operating three CRNE 10-6 pumps in parallel duty, the booster automatically cuts pumps in and out to track line velocity. Quote part number 99752293 to have the entire pre-commissioned assembly delivered to site.
The booster provides up to 905 L/min of total clean-water capacity. Up to 89 metres of shut-off head is generated to overcome vertical riser friction. Advanced Multi-Master firmware shares operating duties directly between pump heads, providing immediate fail-safe handover if an individual drive is isolated.
Delivered as a factory-tested pumping assembly, the set incorporates 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 18.6 A (3 x 6.2 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 system provides dedicated plant room boosting for food production facilities, logistics distribution hubs and aquatic sports centres, keeping line velocity balanced. Variable-speed motor modulation makes the set a practical clean-water pressure-boosting solution for both new plant rooms and system upgrades.
FEATURES
- Frequency converters on the motors pair with IE5 permanent magnet motors for efficient part-load operation.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.
- The system protects its pumps against dry running if the incoming supply is lost.
- Maximum operating pressure of 10 bar with motors sealed to IP55.
- Stainless steel manifolds provide two 80 mm manifold connections ready for plant pipework.
- Energy draw matches the actual job because speed follows demand, not a fixed curve.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a smartphone.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- Pump staging follows demand automatically: pumps enter at low speed as pressure drops, ramp to equal speed, and exit as flow fades.
- Three Grundfos CRNE 10-6 pumps share the boosting work in parallel.
- Each main pump is rated 3 kW (P2), so per-pump draw scales down as speed follows demand.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- Constant pressure control holds the delivered pressure flat while proportional mode lets setpoints flex with demand.
