Product Overview
Industrial machinery manufacturing workshops maintaining wash-down circuits install the Hydro Multi-E 3 CRNE 10-4. Three Grundfos CRNE 10-4 multistage pumps share the hydraulic load across a common skid, staging smoothly to match real-time draw. Quote part number 99752284 to have the entire pre-commissioned assembly delivered to site.
The engineered package delivers up to 905 L/min of dependable fluid volume. Up to 60 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.
Arriving pre-configured on an industrial skid, the set brings together stainless steel pipework, two 80 mm manifold connections, isolation and non-return valves, pressure sensors, plus a 24L diaphragm tank. It connects to a 1 x 200-240 V supply at 50 / 60 Hz with combined rated current of 26.3 A (3 x 8.77 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 provides reliable pressure boosting across hospital surgical wings, aged-care complexes and industrial process supply, preventing fixture starvation. Variable-speed motor modulation makes the set a practical clean-water pressure-boosting solution for both new plant rooms and system upgrades.
FEATURES
- Both constant-pressure and proportional-pressure modes are available, so plant rooms can tune response to pipework.
- Maximum operating pressure of 10 bar with motors sealed to IP55.
- 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.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a smartphone.
- Stainless steel manifolds provide two 80 mm manifold connections ready for plant pipework.
- Three Grundfos CRNE 10-4 pumps share the boosting work in parallel.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- Rated 1.5 kW (P2) on every main pump in the frame.
- The system protects its pumps against dry running if the incoming supply is lost.
- Slow-speed duty and staged switching keep consumption down through low-demand hours.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.
