Product Overview
Residential towers and medium commercial sites outgrowing their mains pressure rely on booster systems with no tolerance for pressure variation, and the Hydro Multi-E 2 CRNE 10-1 is engineered for exactly that duty. Specify part number 99752266 and the whole set lands tested, assembled and ready for pipework.
The system supports flow rates up to 511 L/min. It can develop up to 14 metres of head for dependable pressure boosting. Because every pump carries its own frequency converter and the Multi-Master software elects the controlling pump itself, losing a control unit or pressure sensor means seamless handover rather than a shutdown.
Factory assembled on a common base, the set combines stainless steel pipework, two 50 mm manifold connections, isolation and non-return valves, pressure sensors and a gauge, plus a 24L diaphragm tank. It connects to a 3 x 380-415 V supply at 50 / 60 Hz with a rated current of 2.94 A. Motors are protected to IP55, while maximum system pressure is 10 bar. Liquid-temperature suitability is 5°C to 60°C. Inlet pressure is rated to 10 bar.
Applications include mixed-use commercial buildings, hotel plant rooms and schools and universities. The control flexibility suits clean-water boosting in new installations and upgrades.
Features
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- Both constant-pressure and proportional-pressure modes are available, so plant rooms can tune response to pipework.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.
- Pumps are cut in and out according to demand, every running unit turning at the same speed to hold the pressure set point.
- Setup and monitoring run through the Grundfos GO app rather than a panel visit.
- Stainless steel manifolds provide two 50 mm manifold connections ready for pipework.
- Energy draw matches the actual job because speed follows demand, not a fixed curve.
- Each main pump is rated 0.55 kW (P2), so per-pump draw scales down as speed follows demand.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- The system pairs two CRNE 10-1 pumps in parallel duty, controlled as a single coordinated system.
- Variable speed comes from frequency converters matched to IE5 permanent magnet motors, keeping the booster set in its efficient range.
- The system protects its pumps against dry running if the incoming supply is lost.
- Rated for 10 bar system pressure; motors carry IP55 protection.

What electrical motor technology drives the vertical multistage pumps in this booster assembly?
Electronic speed regulation across the Grundfos Hydro Multi-E 2 CRNE 10-1 U2 A-A-I-I-DU is provided by two IE5 permanent-magnet MGE electric motors rated at 0.55 kW apiece on 3 x 380-415 V power, modulating motor rpm according to demand.
What dynamic head and system working pressure rating does this multi pump booster set maintain?
Hydraulic elevation capability on the Hydro Multi-E 2 CRNE 10-1 generates up to 14 m total dynamic head while supporting a maximum operating pressure rating of 10 bar.
How are the parallel pump stages plumbed with isolating valves and non return check valves?
Common manifolding across the Hydro-Multi-E-2-CRNE-10-1 utilizes R 2 1/2 stainless steel suction and discharge pipework with integrated non-return valves and isolating ball valves.
How is this variable speed booster system protected by factory warranty terms?
Investment protection for the Hydro Multi E 2 CRNE 10 1 features a genuine Grundfos two-year manufacturer warranty supported by nationwide technical service and replacement components.
What peak volumetric water flow can this packaged booster assembly maintain across the network?
For high-demand distribution pipework, the 2 CRNE 10-1 (Hydro Multi-E) delivers a peak water displacement rate of 511 L/min across its parallel multistage pump assembly.
