Product Overview
Convention centres and exhibition halls subject to rapid amenity surge periods depend on the Hydro Multi-E 2 CRE 45-4. Staged parallel operation between two CRE 45-4 pumps maintains consistent line pressure without erratic cycling. Quote part number 93320254 to have the entire pre-commissioned assembly delivered to site.
The multistage assembly develops flow rates up to 2333 L/min under full draw. Up to 150.6 metres of shut-off head is generated to overcome vertical riser friction. Advanced Multi-Master firmware shares operating duties directly between pump heads, providing immediate fail-safe handover if an individual drive is isolated.
Factory aligned on a shared steel chassis, the set combines stainless steel pipework, two 150 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 87.6 A (2 x 43.8 A per pump). Motors carry IP54 sealing with maximum pressure of 16 bar. Liquid-temperature suitability is 5°C to 60°C, and inlet pressure is rated to 16 bar.
Installation sites frequently encompass food production facilities, logistics distribution hubs and aquatic sports centres, where automated pump rotation protects service life. Variable-speed motor modulation makes the set a practical clean-water pressure-boosting solution for both new plant rooms and system upgrades.
FEATURES
- Maximum operating pressure of 16 bar with motors sealed to IP54.
- Stainless steel manifolds provide two 150 mm manifold connections ready for plant pipework.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.
- Variable speed comes from frequency converters matched to IE5 permanent magnet motors, keeping the booster set in its efficient range.
- Energy draw matches the actual job because speed follows demand, not a fixed curve.
- The system protects its pumps against dry running if the incoming supply is lost.
- Cascade logic brings pumps on-line and off-line against changing demand without manual intervention.
- Both constant-pressure and proportional-pressure modes are available, so plant rooms can tune response to pipework.
- Two Grundfos CRE 45-4 pumps share the boosting work in parallel.
- 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.
- Rated 26 kW (P2) on every main pump in the frame.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
