Product Overview
Luxury coastal resorts managing extensive guest villa water networks depend on the Hydro Multi-E 2 CRNE 45-2. The package operates two Grundfos CRNE 45-2 vertical multistage pumps in parallel, automatically staging each unit as flow demand increases. Part number 93368423 provides the complete tested package in a single order line.
Delivering volumetric throughput up to 2333 L/min across busy plant lines, Multistage vertical hydraulics produce up to 75 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.
Mounted on an engineered plant room skid, the booster incorporates stainless steel manifolds, 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 39.2 A (2 x 19.6 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.
Commercial specifications frequently call for the set across high-rise apartments, hotel plant rooms and schools and universities to satisfy peak demand. Variable-speed motor modulation makes the set a practical clean-water pressure-boosting solution for both new plant rooms and system upgrades.
FEATURES
- Pumps are cut in and out according to demand, every running unit turning at the same speed to hold the pressure set point.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- Maximum operating pressure of 10 bar with motors sealed to IP54.
- Rated 15 kW (P2) on every main pump in the frame.
- Energy draw matches the actual job because speed follows demand, not a fixed curve.
- Each pump is driven by IE5 permanent magnet motors with frequency-controlled speed matching demand.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- The system protects its pumps against dry running if the incoming supply is lost.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.
- Two Grundfos CRNE 45-2 pumps share the boosting work in parallel.
- Stainless steel manifolds provide two 150 mm manifold connections ready for plant pipework.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a smartphone.
- Both constant-pressure and proportional-pressure modes are available, so plant rooms can tune response to pipework.
