Product Overview
Suburban shopping plazas with high restaurant and cafe density depend on the Hydro Multi-E 2 CRNE 5-16. Configured with two CRNE 5-16 vertical pumps in parallel, the booster dynamically matches motor speed to immediate water requirements. Everything is ordered under the single manufacturer part number 99752249.
The variable-speed system supplies up to 340 L/min of peak volumetric flow. The vertical stage assembly can build up to 158 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 common fabricated skid, the booster package 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 3 x 380-415 V supply at 50 Hz with combined rated current of 12.4 A (2 x 6.2 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.
Typical commercial plant installations cover mixed-use commercial buildings, corporate office towers and shopping centres, handling changing draw-off patterns. Variable-speed motor modulation makes the set a practical clean-water pressure-boosting solution for both new plant rooms and system upgrades.
FEATURES
- Both constant-pressure and proportional-pressure modes are available, so plant rooms can tune response to pipework.
- Maximum operating pressure of 16 bar with motors sealed to IP55.
- Rated 3 kW (P2) on every main pump in the frame.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.
- Two Grundfos CRNE 5-16 vertical multistage pumps run in parallel on one common base frame.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a smartphone.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- Stainless steel manifolds provide two Rp 2 inch threaded manifold connections ready for plant pipework.
- The system protects its pumps against dry running if the incoming supply is lost.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- Cascade logic brings pumps on-line and off-line against changing demand without manual intervention.
- Each pump is driven by IE5 permanent magnet motors with frequency-controlled speed matching demand.
- Slow-speed duty and staged switching keep consumption down through low-demand hours.
