Product Overview
Multi-storey commercial storage facilities with integrated office suites install the Hydro Multi-E 3 CRNE 5-2. Configured with three CRNE 5-2 vertical pumps in parallel, the booster dynamically matches motor speed to immediate water requirements. Everything is ordered under the single manufacturer part number 99752194.
Operating volume scales up to 510 L/min to eliminate morning pressure sag. The vertical stage assembly can build up to 19 metres of head for steep elevations. Integrated Multi-Master intelligence coordinates the pumps without requiring an external control panel, ensuring automatic role swapping and uninterrupted pressure stabilization.
Mounted on a shared rigid baseplate, the system combines stainless steel manifolds, two Rp 2 inch threaded 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 7.17 A (3 x 2.39 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 plant room sectors encompass mixed-use commercial buildings, corporate office towers and shopping centres, where seamless pump duty handover is essential. Variable-speed motor modulation makes the set a practical clean-water pressure-boosting solution for both new plant rooms and system upgrades.
FEATURES
- Three Grundfos CRNE 5-2 pumps share the boosting work in parallel.
- Stainless steel manifolds provide two Rp 2 inch threaded manifold connections ready for plant pipework.
- Each pump is driven by IE5 permanent magnet motors with frequency-controlled speed matching demand.
- 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.
- Constant pressure control holds the delivered pressure flat while proportional mode lets setpoints flex with demand.
- Dry-running protection is built into the control, protecting the pumps if the suction supply is interrupted.
- Maximum operating pressure of 10 bar with motors sealed to IP55.
- Energy draw matches the actual job because speed follows demand, not a fixed curve.
- Rated 0.37 kW (P2) on every main pump in the frame.
- Cascade logic brings pumps on-line and off-line against changing demand without manual intervention.
- 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.
