Product Overview
Meat packaging wholesale depots running wash-down sanitation lines install the Hydro Multi-E 3 CRNE 5-12. Integrated variable-speed drives coordinate the three CRNE 5-12 pumps in parallel, seamlessly ramping output as fixtures open. Specify part number 99752248 and the complete factory-tested package arrives ready for connection.
Header volume achieves up to 510 L/min under maximum commercial loading. To pressurise elevated upper levels, the pumps develop up to 120 metres of head. 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.
Positioned on an engineered structural skid, the set brings together 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 13.3 A (3 x 4.43 A per pump). Motors carry IP55 sealing with maximum pressure of 16 bar. Liquid-temperature suitability is 5°C to 60°C, and inlet pressure is rated to 16 bar.
The set is widely installed across facilities like high-rise apartments, hotel plant rooms and schools and universities for responsive, staged pressure control. Variable-speed motor modulation makes the set a practical clean-water pressure-boosting solution for both new plant rooms and system upgrades.
FEATURES
- Pumps are cut in and out according to demand, every running unit turning at the same speed to hold the pressure set point.
- Stainless steel manifolds provide two Rp 2 inch threaded manifold connections ready for plant pipework.
- Each main pump is rated 2.2 kW (P2), so per-pump draw scales down as speed follows demand.
- The system pairs three CRNE 5-12 pumps in parallel duty, controlled as a single coordinated system.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- Variable speed comes from frequency converters matched to IE5 permanent magnet motors, keeping the booster set in its efficient range.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- Maximum operating pressure of 16 bar with motors sealed to IP55.
- Constant pressure control holds the delivered pressure flat while proportional mode lets setpoints flex with demand.
- Dry-running protection is built into the control, protecting the pumps if the suction supply is interrupted.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.
- Slow-speed duty and staged switching keep consumption down through low-demand hours.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a smartphone.
