Product Overview
Suburban healthcare complexes maintaining steady consultation basin feeds count on the Hydro Multi-E 2 CRNE 45-1-1. Integrated variable-speed drives coordinate the two CRNE 45-1-1 pumps in parallel, seamlessly ramping output as fixtures open. Specify part number 93368419 and the complete factory-tested package arrives ready for connection.
Volumetric capacity easily scales to 2333 L/min during heavy morning use. To pressurise elevated upper levels, the pumps develop up to 31 metres of 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.
Engineered as a plug-and-play plant room skid, the assembly features 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 27.2 A (2 x 13.6 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.
Suited to multi-fixture commercial layouts like high-rise apartments, hotel plant rooms and schools and universities, the system ensures uniform pressure. 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.
- Two Grundfos CRNE 45-1-1 vertical multistage pumps run in parallel on one common base frame.
- Slow-speed duty and staged switching keep consumption down through low-demand hours.
- Frequency converters on the motors pair with IE5 permanent magnet motors for efficient part-load operation.
- 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.
- Cascade logic brings pumps on-line and off-line against changing demand without manual intervention.
- The system protects its pumps against dry running if the incoming supply is lost.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- Rated 4 kW (P2) on every main pump in the frame.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.
- Maximum operating pressure of 10 bar with motors sealed to IP54.
- Both constant-pressure and proportional-pressure modes are available, so plant rooms can tune response to pipework.
