Product Overview
City fringe co-working spaces and high-density tech hubs balance water feeds with the Hydro Multi-E 3 CRNE 5-2. Operating three CRNE 5-2 pumps in parallel duty, the booster automatically cuts pumps in and out to track line velocity. The complete booster system ships factory assembled and certified under part number 99752196.
Supplying up to 510 L/min of steady water volume under full cascade, Line pressure is maintained with up to 19 metres of maximum delivery head. Advanced Multi-Master firmware shares operating duties directly between pump heads, providing immediate fail-safe handover if an individual drive is isolated.
Pre-built on a shared structural frame, the booster combines stainless steel pipework, two Rp 2 inch threaded manifold connections, isolation and non-return valves, pressure sensors, plus a 24L diaphragm tank. It connects to a 3 x 380-415 V supply at 50 / 60 Hz with combined rated current of 3.42 A (3 x 1.14 A per pump). Motors carry IP55 sealing with maximum pressure of 10 bar. Liquid-temperature suitability is 5°C to 60°C, and inlet pressure is rated to 10 bar.
The booster delivers constant line pressure across food production facilities, logistics distribution hubs and aquatic sports centres, matching motor speed to flow. Variable-speed motor modulation makes the set a practical clean-water pressure-boosting solution for both new plant rooms and system upgrades.
FEATURES
- Variable speed comes from frequency converters matched to IE5 permanent magnet motors, keeping the booster set in its efficient range.
- Energy draw matches the actual job because speed follows demand, not a fixed curve.
- Maximum operating pressure of 10 bar with motors sealed to IP55.
- Rated 0.37 kW (P2) on every main pump in the frame.
- Pump staging follows demand automatically: pumps enter at low speed as pressure drops, ramp to equal speed, and exit as flow fades.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.
- Dry-running protection is built into the control, protecting the pumps if the suction supply is interrupted.
- The controller tracks the pressure setpoint with proportional deviation alerts before conditions become faults.
- Stainless steel manifolds provide two Rp 2 inch threaded manifold connections ready for plant pipework.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- Three Grundfos CRNE 5-2 vertical multistage pumps run in parallel on one common base frame.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a smartphone.
