Product Overview
Correctional facility blocks requiring tamper-proof, redundant water boosting operate the Hydro Multi-E 2 CRNE 5-12. Two Grundfos CRNE 5-12 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 99752247.
Peak line volume reaches up to 340 L/min across active commercial branches. Line pressure is maintained with up to 120 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.
Pre-plumbed on an industrial base chassis, the system 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 8.86 A (2 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.
Plumbing contractors routinely install the set across hospital surgical wings, aged-care complexes and industrial process supply for straightforward plant hookup. Variable-speed motor modulation makes the set a practical clean-water pressure-boosting solution for both new plant rooms and system upgrades.
FEATURES
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a smartphone.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.
- Constant pressure control holds the delivered pressure flat while proportional mode lets setpoints flex with demand.
- Maximum operating pressure of 16 bar with motors sealed to IP55.
- Two Grundfos CRNE 5-12 vertical multistage pumps run in parallel on one common base frame.
- Variable speed comes from frequency converters matched to IE5 permanent magnet motors, keeping the booster set in its efficient range.
- Rated 2.2 kW (P2) on every main pump in the frame.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- Dry-running protection is built into the control, protecting the pumps if the suction supply is interrupted.
- Power use precisely tracks demand, avoiding the waste of fixed-speed alternates.
- 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.
- Pumps are cut in and out according to demand, every running unit turning at the same speed to hold the pressure set point.
