Product Overview
Urban transit terminal hubs maintaining heavy-traffic public amenities select the Hydro Multi-E 3 CRNE 10-9. The package operates three Grundfos CRNE 10-9 vertical multistage pumps in parallel, automatically staging each unit as flow demand increases. Specify part number 99752296 and the complete factory-tested package arrives ready for connection.
Header flow capacity reaches up to 905 L/min during intensive use periods. To pressurise elevated upper levels, the pumps develop up to 133 metres of head. Because every pump carries its own frequency converter and Multi-Master software elects the controlling pump itself, losing a control unit or pressure sensor means seamless handover rather than a shutdown.
Mounted on an industrial channel-iron skid, the package combines stainless steel manifolds, 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 24.3 A (3 x 8.1 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.
Commercial facilities such as high-rise apartments, hotel plant rooms and schools and universities rely on the package for smooth, inverter-driven flow. Variable-speed motor modulation makes the set a practical clean-water pressure-boosting solution for both new plant rooms and system upgrades.
FEATURES
- Energy draw matches the actual job because speed follows demand, not a fixed curve.
- Pump staging follows demand automatically: pumps enter at low speed as pressure drops, ramp to equal speed, and exit as flow fades.
- Each main pump is rated 4 kW (P2), so per-pump draw scales down as speed follows demand.
- Constant pressure control holds the delivered pressure flat while proportional mode lets setpoints flex with demand.
- Stainless steel manifolds provide two 80 mm manifold connections ready for plant pipework.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- Three Grundfos CRNE 10-9 vertical multistage pumps run in parallel on one common base frame.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- Maximum operating pressure of 16 bar with motors sealed to IP55.
- The system protects its pumps against dry running if the incoming supply is lost.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a smartphone.
- Variable speed comes from frequency converters matched to IE5 permanent magnet motors, keeping the booster set in its efficient range.
