Product Overview
Sites such as boutique motels and dental suites whose tenants notice every pressure dip require consistent pressure regardless of demand fluctuation; the Hydro Multi-E 2 CRNE 5-7 achieves this with two CRNE 5-7 pumps operating in parallel. The complete system ships factory assembled and tested under part number 99752213.
It handles flows up to 291 L/min across the system. The pumps can develop up to 66 metres of head when pressure demand increases. 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 12.9 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 hotel plant rooms, mixed-use commercial buildings and high-rise apartments. The control flexibility suits clean-water boosting in new installations and upgrades.
Features
- The stainless steel manifold assembly is supplied with two 50 mm manifold connections.
- Each main pump is rated 1.1 kW (P2), so per-pump draw scales down as speed follows demand.
- Setup and monitoring run through the Grundfos GO app rather than a panel visit.
- 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.
- Slow-speed duty and staged switching keep consumption down through low-demand hours.
- Pump staging follows demand automatically: pumps enter at low speed as pressure drops, ramp to equal speed, and exit as flow fades.
- Rated for 10 bar system pressure; motors carry IP55 protection.
- Two Grundfos CRNE 5-7 pumps share the boosting work in parallel.
- Dry-running protection is built into the control, protecting the pumps if the suction supply is interrupted.
- Each pump is driven by IE5 permanent magnet motors with frequency-controlled speed matching demand.
- 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.
