Product Overview
Urban boutique hotel conversions outgrowing restricted municipal street mains choose the Hydro Multi-E 3 CRNE 5-16. The three-pump parallel layout shares duty evenly across the CRNE 5-16 wet ends, preserving steady pressure during morning spikes. The complete booster system ships factory assembled and certified under part number 99752251.
The multistage system delivers up to 510 L/min across building risers. Line pressure is maintained with up to 158 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.
Delivered ready for plant room piping, the package includes 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 18.6 A (3 x 6.2 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.
Plant room specifications routinely select the package for hospital surgical wings, aged-care complexes and industrial process supply to achieve stable flow. 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.
- Each pump is driven by IE5 permanent magnet motors with frequency-controlled speed matching demand.
- Maximum operating pressure of 16 bar with motors sealed to IP55.
- Rated 3 kW (P2) on every main pump in the frame.
- Pumps are cut in and out according to demand, every running unit turning at the same speed to hold the pressure set point.
- Slow-speed duty and staged switching keep consumption down through low-demand hours.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- The controller tracks the pressure setpoint with proportional deviation alerts before conditions become faults.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.
- Three Grundfos CRNE 5-16 pumps share the boosting work in parallel.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a smartphone.
- Stainless steel manifolds provide two Rp 2 inch threaded manifold connections ready for plant pipework.
- Dry-running protection is built into the control, protecting the pumps if the suction supply is interrupted.
