Product Overview
School blocks and council facilities fed by long, pressure-hungry reticulation rely on booster systems with no tolerance for pressure variation, and the Hydro Multi-E 2 CRNE 20-2 is engineered for exactly that duty. One factory-tested package replaces a shelf of loose components; order part number 99752352 to put it on site.
The system supports flow rates up to 1103 L/min. It can develop up to 40 metres of head for dependable pressure boosting. 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.
For installation, the booster is supplied pre-assembled with stainless steel manifolds, two 80 mm manifold connections, isolation valves, non-return valves, pressure sensors and a gauge, plus a 24L diaphragm tank. It is designed for 3 x 380-415 V power at 50 / 60 Hz with a rated current of 12.4 A, with IP55 motor protection and a 10 bar maximum system pressure. Liquid-temperature suitability is 5°C to 60°C. Inlet pressure is rated to 10 bar.
Typical duty sits with hotel plant rooms, industrial process supply and hospitals. It is designed for clean-water pressure boosting where demand varies through the day.
Features
- Cascade logic brings pumps on-line and off-line against changing demand without manual intervention.
- Rated for 10 bar system pressure; motors carry IP55 protection.
- Energy draw matches the actual job because speed follows demand, not a fixed curve.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- The controller tracks the pressure setpoint with proportional deviation alerts before conditions become faults.
- Dry-running protection is built into the control, protecting the pumps if the suction supply is interrupted.
- Stainless steel manifolds provide two 80 mm manifold connections ready for pipework.
- Two Grundfos CRNE 20-2 pumps share the boosting work in parallel.
- Setup and monitoring run through the Grundfos GO app rather than a panel visit.
- The package is wet-tested and pre-configured, requiring only pipework and power on site.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.
- Rated 3 kW (P2) on every main pump in the frame.
- Each pump is driven by IE5 permanent magnet motors with frequency-controlled speed matching demand.
