Product Overview
High-rise hotel kitchens and central dishwashing banks maintain line pressure through the Hydro Multi-E 2 CRNE 5-7. Operating two CRNE 5-7 pumps in parallel duty, the booster automatically cuts pumps in and out to track line velocity. Quote part number 99752221 to have the entire pre-commissioned assembly delivered to site.
At peak operating velocity, the system flows up to 340 L/min. Up to 69 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.
Engineered on an integrated floor skid, the booster pairs 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 4.74 A (2 x 2.37 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.
Institutional applications cover facilities like food production facilities, logistics distribution hubs and aquatic sports centres, where uninterrupted water is critical. Variable-speed motor modulation makes the set a practical clean-water pressure-boosting solution for both new plant rooms and system upgrades.
FEATURES
- Stainless steel manifolds provide two Rp 2 inch threaded manifold connections ready for plant pipework.
- Dry-running protection is built into the control, protecting the pumps if the suction supply is interrupted.
- Pumps are cut in and out according to demand, every running unit turning at the same speed to hold the pressure set point.
- Maximum operating pressure of 10 bar with motors sealed to IP55.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- The system pairs two CRNE 5-7 pumps in parallel duty, controlled as a single coordinated system.
- Both constant-pressure and proportional-pressure modes are available, so plant rooms can tune response to pipework.
- Power use precisely tracks demand, avoiding the waste of fixed-speed alternates.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a smartphone.
- At P2 each main pump is 1.1 kW, covering the duty without oversizing the frame.
- 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.
