Product Overview
High-rise luxury penthouses demanding whisper-quiet, inverter-regulated boosting install the Hydro Multi-E 3 CRE 45-2. The three-pump parallel layout shares duty evenly across the CRE 45-2 wet ends, preserving steady pressure during morning spikes. The complete booster system ships factory assembled and certified under part number 93320249.
Continuous supply capacity reaches up to 3500 L/min across the network. Line pressure is maintained with up to 75 metres of maximum delivery head. There is no separate central controller to purchase: Multi-Master control resides within the pumps, either unit can assume the controlling role, and a fault is handed over cleanly without interrupting supply.
Supplied ready for plant room connection, the assembly integrates stainless steel pipework, two 200 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 58.7 A (3 x 19.57 A per pump). Motors carry IP54 sealing with maximum pressure of 10 bar. Liquid-temperature suitability is 5°C to 60°C, and inlet pressure is rated to 10 bar.
Hydraulic consulting engineers specify the package for hospital surgical wings, aged-care complexes and industrial process supply to balance dynamic water usage. 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 CRE 45-2 vertical multistage pumps run in parallel on one common base frame.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.
- 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.
- Rated 11 kW (P2) on every main pump in the frame.
- The system protects its pumps against dry running if the incoming supply is lost.
- 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.
- Stainless steel manifolds provide two 200 mm manifold connections ready for plant pipework.
- 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 IP54.
- Variable speed comes from frequency converters matched to IE5 permanent magnet motors, keeping the booster set in its efficient range.
- Power use precisely tracks demand, avoiding the waste of fixed-speed alternates.
