Product Overview
Light industrial unit complexes sharing a common water boundary ring depend on the Hydro Multi-E 2 CRNE 15-5. The package operates two Grundfos CRNE 15-5 vertical multistage pumps in parallel, automatically staging each unit as flow demand increases. Everything is ordered under the single manufacturer part number 99752337.
Header capacity accommodates peak simultaneous flows up to 933 L/min. The vertical stage assembly can build up to 102 metres of head for steep elevations. 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.
Pre-built on a vibration-isolated chassis, the assembly features 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 21.9 A (2 x 10.95 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.
Designed for commercial plant rooms, the set serves high-rise apartments, hotel plant rooms and schools and universities with steady, modulated pressure. Variable-speed motor modulation makes the set a practical clean-water pressure-boosting solution for both new plant rooms and system upgrades.
FEATURES
- The controller tracks the pressure setpoint with proportional deviation alerts before conditions become faults.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a smartphone.
- Cascade logic brings pumps on-line and off-line against changing demand without manual intervention.
- Frequency converters on the motors pair with IE5 permanent magnet motors for efficient part-load operation.
- 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.
- Each main pump is rated 5.5 kW (P2), so per-pump draw scales down as speed follows demand.
- Power use precisely tracks demand, avoiding the waste of fixed-speed alternates.
- The system protects its pumps against dry running if the incoming supply is lost.
- Two Grundfos CRNE 15-5 pumps share the boosting work in parallel.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- Stainless steel manifolds provide two 80 mm manifold connections ready for plant pipework.
- Maximum operating pressure of 16 bar with motors sealed to IP55.
