Product Overview
Public transport interchanges handling heavy daily commuter amenity traffic select the Hydro Multi-E 2 CRNE 45-4. Staged parallel operation between two CRNE 45-4 pumps maintains consistent line pressure without erratic cycling. The complete booster system ships factory assembled and certified under part number 93368429.
Discharge performance easily reaches 2333 L/min across simultaneous taps. Line pressure is maintained with up to 150.6 metres of maximum delivery head. Advanced Multi-Master firmware shares operating duties directly between pump heads, providing immediate fail-safe handover if an individual drive is isolated.
Arriving pre-tested and skid-mounted, the package brings together 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 75.4 A (2 x 37.7 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.
Key application environments encompass food production facilities, logistics distribution hubs and aquatic sports centres, where automated staging prevents line hammer. Variable-speed motor modulation makes the set a practical clean-water pressure-boosting solution for both new plant rooms and system upgrades.
FEATURES
- Stainless steel manifolds provide two 150 mm manifold connections ready for plant pipework.
- Pumps are cut in and out according to demand, every running unit turning at the same speed to hold the pressure set point.
- Each pump is driven by IE5 permanent magnet motors with frequency-controlled speed matching demand.
- 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.
- Slow-speed duty and staged switching keep consumption down through low-demand hours.
- At P2 each main pump is 26 kW, covering the duty without oversizing the frame.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.
- Two Grundfos CRNE 45-4 pumps share the boosting work in parallel.
- Maximum operating pressure of 16 bar with motors sealed to IP54.
- Both constant-pressure and proportional-pressure modes are available, so plant rooms can tune response to pipework.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
