Product Overview
Government administrative complexes maintaining steady multi-floor domestic water specify the Hydro Multi-E 2 CRNE 15-1. Integrated variable-speed drives coordinate the two CRNE 15-1 pumps in parallel, seamlessly ramping output as fixtures open. Part number 99752327 provides the complete tested package in a single order line.
Operating across wide demand swings, the package delivers up to 933 L/min. Multistage vertical hydraulics produce up to 21 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.
Supplied on a shared structural channel, the booster 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 6.2 A (2 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.
Operating environments regularly encompass high-rise apartments, hotel plant rooms and schools and universities, where demand escalates rapidly in morning peaks. Variable-speed motor modulation makes the set a practical clean-water pressure-boosting solution for both new plant rooms and system upgrades.
FEATURES
- Frequency converters on the motors pair with IE5 permanent magnet motors for efficient part-load operation.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- 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.
- Constant pressure control holds the delivered pressure flat while proportional mode lets setpoints flex with demand.
- Each main pump is rated 1.5 kW (P2), so per-pump draw scales down as speed follows demand.
- Two Grundfos CRNE 15-1 vertical multistage pumps run in parallel on one common base frame.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a smartphone.
- Stainless steel manifolds provide two 80 mm manifold connections ready for plant pipework.
- Dry-running protection is built into the control, protecting the pumps if the suction supply is interrupted.
- Cascade logic brings pumps on-line and off-line against changing demand without manual intervention.
- Maximum operating pressure of 10 bar with motors sealed to IP55.
- Power use precisely tracks demand, avoiding the waste of fixed-speed alternates.
