Product Overview
Commercial nursery greenhouses and wholesale growers maintain steady irrigation pressure with the Hydro Multi-E 2 CRNE 5-2. The two-pump parallel layout shares duty evenly across the CRNE 5-2 wet ends, preserving steady pressure during morning spikes. Ordering part number 99752203 puts the fully tested booster skid directly onto the plant room floor.
Header throughput accommodates flow requirements up to 340 L/min. Up to 21 metres of delivery head is available to keep upper-floor fixtures pressurised. 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.
Factory assembled on an anti-vibration base, the assembly combines 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 2.94 A (2 x 1.47 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.
Plant rooms across hospital surgical wings, aged-care complexes and industrial process supply benefit from the compact footprint and automated control. Variable-speed motor modulation makes the set a practical clean-water pressure-boosting solution for both new plant rooms and system upgrades.
FEATURES
- Rated 0.55 kW (P2) on every main pump in the frame.
- Both constant-pressure and proportional-pressure modes are available, so plant rooms can tune response to 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.
- Maximum operating pressure of 10 bar with motors sealed to IP55.
- Stainless steel manifolds provide two Rp 2 inch threaded manifold connections ready for plant pipework.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.
- Variable speed comes from frequency converters matched to IE5 permanent magnet motors, keeping the booster set in its efficient range.
- Pumps are cut in and out according to demand, every running unit turning at the same speed to hold the pressure set point.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- Two Grundfos CRNE 5-2 vertical multistage pumps run in parallel on one common base frame.
- Slow-speed duty and staged switching keep consumption down through low-demand hours.
