Product Overview
Suburban community centres and library facilities regulate shared water pressure with the Hydro Multi-E 2 CRNE 5-2. Integrated variable-speed drives coordinate the two CRNE 5-2 pumps in parallel, seamlessly ramping output as fixtures open. Everything is ordered under the single manufacturer part number 99752195.
Supplying up to 340 L/min of stable clean-water volume, The vertical stage assembly can build up to 19 metres of head for steep elevations. Because every pump carries its own frequency converter and Multi-Master software elects the controlling pump itself, losing a control unit or pressure sensor means seamless handover rather than a shutdown.
Pre-fitted on a common structural steel frame, the booster features stainless steel manifolds, 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 2.28 A (2 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 system delivers constant-pressure boosting across high-rise apartments, hotel plant rooms and schools and universities, ensuring dependable daily supply. Variable-speed motor modulation makes the set a practical clean-water pressure-boosting solution for both new plant rooms and system upgrades.
FEATURES
- Maximum operating pressure of 10 bar with motors sealed to IP55.
- Variable speed comes from frequency converters matched to IE5 permanent magnet motors, keeping the booster set in its efficient range.
- Cascade logic brings pumps on-line and off-line against changing demand without manual intervention.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.
- Power use precisely tracks demand, avoiding the waste of fixed-speed alternates.
- 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.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- Two Grundfos CRNE 5-2 pumps share the boosting work in parallel.
- Stainless steel manifolds provide two Rp 2 inch threaded manifold connections ready for plant pipework.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a smartphone.
- The system protects its pumps against dry running if the incoming supply is lost.
- At P2 each main pump is 0.37 kW, covering the duty without oversizing the frame.
