Product Overview
Major retail department stores maintaining multi-level amenities operate the Hydro Multi-E 3 CRNE 5-8. Staged parallel operation between three CRNE 5-8 pumps maintains consistent line pressure without erratic cycling. Quote part number 99752245 to have the entire pre-commissioned assembly delivered to site.
Continuous fluid movement reaches up to 510 L/min across all outlets. Up to 79 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.
Factory piped on a sturdy channel chassis, the assembly combines 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 9.3 A (3 x 3.1 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.
Commercial building services installations cover food production facilities, logistics distribution hubs and aquatic sports centres, where reliable pressure is mandatory. Variable-speed motor modulation makes the set a practical clean-water pressure-boosting solution for both new plant rooms and system upgrades.
FEATURES
- Three Grundfos CRNE 5-8 vertical multistage pumps run in parallel on one common base frame.
- 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.
- Cascade logic brings pumps on-line and off-line against changing demand without manual intervention.
- Variable speed comes from frequency converters matched to IE5 permanent magnet motors, keeping the booster set in its efficient range.
- Maximum operating pressure of 10 bar with motors sealed to IP55.
- Stainless steel manifolds provide two Rp 2 inch threaded manifold connections ready for plant pipework.
- Constant pressure control holds the delivered pressure flat while proportional mode lets setpoints flex with demand.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a smartphone.
- 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.
- The system protects its pumps against dry running if the incoming supply is lost.
- Rated 1.5 kW (P2) on every main pump in the frame.
