Product Overview
Civic cultural centres and performing arts theatres maintain amenities with the Hydro Multi-E 3 CRNE 10-4. The three-pump parallel layout shares duty evenly across the CRNE 10-4 wet ends, preserving steady pressure during morning spikes. Ordering part number 99752288 puts the fully tested booster skid directly onto the plant room floor.
Supplying up to 905 L/min of pressurized water across facility mains, Up to 60 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.
Supplied on an engineered floor-mounted chassis, the assembly 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 3 x 380-415 V supply at 50 / 60 Hz with combined rated current of 9.3 A (3 x 3.1 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 booster delivers seamless pressure regulation across hospital surgical wings, aged-care complexes and industrial process supply, adapting instantly to changes. Variable-speed motor modulation makes the set a practical clean-water pressure-boosting solution for both new plant rooms and system upgrades.
FEATURES
- The controller tracks the pressure setpoint with proportional deviation alerts before conditions become faults.
- Rated 1.5 kW (P2) on every main pump in the frame.
- Three Grundfos CRNE 10-4 pumps share the boosting work in parallel.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.
- Frequency converters on the motors pair with IE5 permanent magnet motors for efficient part-load operation.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- 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.
- Dry-running protection is built into the control, protecting the pumps if the suction supply is interrupted.
- Maximum operating pressure of 10 bar with motors sealed to IP55.
- 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.
