Product Overview
Across installations such as mixed-use buildings where a single booster covers retail, offices and apartments, the Hydro Multi-E 2 CRNE 10-2 maintains stable pressure at every draw-off point. Specify part number 99752270 and the whole set lands tested, assembled and ready for pipework.
This set provides up to 449 L/min of flow capacity. Variable-speed operation can develop up to 29 metres of head where required. There is no separate central controller to purchase: Multi-Master control resides within the pumps, either unit can assume the controlling role, and a fault is handed over cleanly without interrupting supply.
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 1 x 200-240 V supply at 50 / 60 Hz with a rated current of 9.02 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 industrial process supply, hotel plant rooms and schools and universities. The control flexibility suits clean-water boosting in new installations and upgrades.
Features
- No external controller required: Multi-Master redundancy lets either pump assume the controlling role.
- Dry-running protection is built into the control, protecting the pumps if the suction supply is interrupted.
- Both constant-pressure and proportional-pressure modes are available, so plant rooms can tune response to pipework.
- Cascade logic brings pumps on-line and off-line against changing demand without manual intervention.
- At P2 each main pump is 0.75 kW, covering the duty without oversizing the frame.
- Two Grundfos CRNE 10-2 pumps share the boosting work in parallel.
- Rated for 10 bar system pressure; motors carry IP55 protection.
- Each pump is driven by IE5 permanent magnet motors with frequency-controlled speed matching demand.
- The package is wet-tested and pre-configured, requiring only pipework and power on site.
- Slow-speed duty and staged switching keep consumption down through low-demand hours.
- The stainless steel manifold assembly is supplied with two 50 mm manifold connections.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a phone.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
