Product Overview
Regional community sports pavilions managing weekend game demand select the Hydro Multi-E 3 CRNE 10-2. The package operates three Grundfos CRNE 10-2 vertical multistage pumps in parallel, automatically staging each unit as flow demand increases. Part number 99752279 provides the complete tested package in a single order line.
Providing high volumetric performance up to 905 L/min across peak hours, Multistage vertical hydraulics produce up to 29 metres of maximum 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.
Constructed on a heavy-duty mounting frame, the assembly incorporates stainless steel manifolds, two 80 mm manifold connections, isolation and non-return valves, pressure sensors, plus a 24L diaphragm tank. It connects to a 1 x 200-240 V supply at 50 / 60 Hz with combined rated current of 19.4 A (3 x 6.47 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.
Key commercial installations regularly feature the set across high-rise apartments, hotel plant rooms and schools and universities for constant line pressure. Variable-speed motor modulation makes the set a practical clean-water pressure-boosting solution for both new plant rooms and system upgrades.
FEATURES
- Each main pump is rated 1.1 kW (P2), so per-pump draw scales down as speed follows demand.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.
- Stainless steel manifolds provide two 80 mm manifold connections ready for plant pipework.
- Cascade logic brings pumps on-line and off-line against changing demand without manual intervention.
- The system protects its pumps against dry running if the incoming supply is lost.
- Power use precisely tracks demand, avoiding the waste of fixed-speed alternates.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a smartphone.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- 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.
- Three Grundfos CRNE 10-2 pumps share the boosting work in parallel.
- The controller tracks the pressure setpoint with proportional deviation alerts before conditions become faults.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
