Product Overview
For gymnasiums, aquatic centres and student housing running wall-to-wall showers, a factory-assembled Hydro Multi-E 2 CRNE 20-3 package provides a well-matched solution, with two CRNE 20-3 pumps staged against the demand curve. One factory-tested package replaces a shelf of loose components; order part number 99752365 to put it on site.
Flow capacity reaches 1063 L/min. Up to 61 metres of head is available to maintain pressure as demand changes. 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 80 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 16.2 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.
Its home ground covers mixed-use commercial buildings, schools and universities and hotel plant rooms. The variable-speed system suits clean-water boosting duties with changing demand.
Features
- Rated for 10 bar system pressure; motors carry IP55 protection.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a phone.
- Energy draw matches the actual job because speed follows demand, not a fixed curve.
- Rated 4 kW (P2) on every main pump in the frame.
- Stainless steel manifolds provide two 80 mm manifold connections ready for pipework.
- The package is wet-tested and pre-configured, requiring only pipework and power on site.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- Both constant-pressure and proportional-pressure modes are available, so plant rooms can tune response to pipework.
- Two Grundfos CRNE 20-3 pumps share the boosting work in parallel.
- Cascade logic brings pumps on-line and off-line against changing demand without manual intervention.
- Dry-running protection is built into the control, protecting the pumps if the suction supply is interrupted.
- Frequency converters on the motors pair with IE5 permanent magnet motors for efficient part-load operation.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.
