Product Overview
Airport terminal concourses managing non-stop passenger restroom flows rely on the Hydro Multi-E 2 CRNE 45-2-2. Two Grundfos CRNE 45-2-2 multistage pumps work in unison on the base frame, modulating rotational speed to follow the facility draw curve. Everything is ordered under the single manufacturer part number 93368425.
Under peak amenity loading, total throughput reaches up to 2333 L/min. The vertical stage assembly can build up to 59.8 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.
Delivered factory-tested on an integrated chassis, the system includes 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 51.6 A (2 x 25.8 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.
The booster system is well adapted to mixed-use commercial buildings, corporate office towers and shopping centres, managing varying daily occupancy levels. Variable-speed motor modulation makes the set a practical clean-water pressure-boosting solution for both new plant rooms and system upgrades.
FEATURES
- The controller tracks the pressure setpoint with proportional deviation alerts before conditions become faults.
- Two Grundfos CRNE 45-2-2 pumps share the boosting work in parallel.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- Cascade logic brings pumps on-line and off-line against changing demand without manual intervention.
- 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.
- The system protects its pumps against dry running if the incoming supply is lost.
- Power use precisely tracks demand, avoiding the waste of fixed-speed alternates.
- Stainless steel manifolds provide two 150 mm manifold connections ready for plant pipework.
- Each main pump is rated 7.5 kW (P2), so per-pump draw scales down as speed follows demand.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- Each pump is driven by IE5 permanent magnet motors with frequency-controlled speed matching demand.
- Maximum operating pressure of 10 bar with motors sealed to IP54.
