Product Overview
Private hospital treatment wings and diagnostic laboratories depend on the Hydro Multi-E 2 CRNE 15-2. The two-pump parallel layout shares duty evenly across the CRNE 15-2 wet ends, preserving steady pressure during morning spikes. Quote part number 99752330 to have the entire pre-commissioned assembly delivered to site.
Hydraulic output reaches up to 933 L/min across the discharge manifold. Up to 41 metres of shut-off head is generated to overcome vertical riser friction. 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-aligned and fully assembled on an engineered skid, the package includes stainless steel pipework, two 80 mm 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 10 bar. Liquid-temperature suitability is 5°C to 60°C, and inlet pressure is rated to 10 bar.
Commercial property engineers select the package for hospital surgical wings, aged-care complexes and industrial process supply to secure long-term pressure. Variable-speed motor modulation makes the set a practical clean-water pressure-boosting solution for both new plant rooms and system upgrades.
FEATURES
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- Variable speed comes from frequency converters matched to IE5 permanent magnet motors, keeping the booster set in its efficient range.
- Pump staging follows demand automatically: pumps enter at low speed as pressure drops, ramp to equal speed, and exit as flow fades.
- Maximum operating pressure of 10 bar with motors sealed to IP55.
- Stainless steel manifolds provide two 80 mm manifold connections ready for plant pipework.
- Rated 2.2 kW (P2) on every main pump in the frame.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.
- The system pairs two CRNE 15-2 pumps in parallel duty, controlled as a single coordinated system.
- Power use precisely tracks demand, avoiding the waste of fixed-speed alternates.
- Constant pressure control holds the delivered pressure flat while proportional mode lets setpoints flex with demand.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- The system protects its pumps against dry running if the incoming supply is lost.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a smartphone.
