Product Overview
Aviation flight catering kitchens running non-stop tray wash lines specify the Hydro Multi-E 3 CRNE 3-10. Three Grundfos CRNE 3-10 multistage pumps share the hydraulic load across a common skid, staging smoothly to match real-time draw. The complete booster system ships factory assembled and certified under part number 99752177.
Delivering robust volume up to 270 L/min through the stainless manifold, Line pressure is maintained with up to 96 metres of maximum delivery head. 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.
Engineered on a compact plant room skid, the assembly features 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 7.11 A (3 x 2.37 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 assembly is routinely deployed across hospital surgical wings, aged-care complexes and industrial process supply, providing quiet, reliable pressure boosting. Variable-speed motor modulation makes the set a practical clean-water pressure-boosting solution for both new plant rooms and system upgrades.
FEATURES
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- Pumps are cut in and out according to demand, every running unit turning at the same speed to hold the pressure set point.
- 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.
- Frequency converters on the motors pair with IE5 permanent magnet motors for efficient part-load operation.
- Maximum operating pressure of 10 bar with motors sealed to IP55.
- The controller tracks the pressure setpoint with proportional deviation alerts before conditions become faults.
- Dry-running protection is built into the control, protecting the pumps if the suction supply is interrupted.
- The system pairs three CRNE 3-10 pumps in parallel duty, controlled as a single coordinated system.
- Stainless steel manifolds provide two Rp 2 inch threaded manifold connections ready for plant pipework.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.
- Each main pump is rated 1.1 kW (P2), so per-pump draw scales down as speed follows demand.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a smartphone.
