Product Overview
Commercial bakery plants running multi-shift steam and wash-down feeds select the Hydro Multi-E 2 CRNE 15-8. Two Grundfos CRNE 15-8 multistage pumps share the hydraulic load across a common skid, staging smoothly to match real-time draw. Ordering part number 99752340 puts the fully tested booster skid directly onto the plant room floor.
Maximum volumetric delivery easily sustains flow rates up to 933 L/min. Up to 160 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.
Delivered factory-piped on a shared steel frame, the booster 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 30 A (2 x 15 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.
The assembly delivers reliable pressure boosting across hospital surgical wings, aged-care complexes and industrial process supply, safeguarding tenant comfort. Variable-speed motor modulation makes the set a practical clean-water pressure-boosting solution for both new plant rooms and system upgrades.
FEATURES
- Energy draw matches the actual job because speed follows demand, not a fixed curve.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.
- 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.
- Stainless steel manifolds provide two 80 mm manifold connections ready for plant pipework.
- Both constant-pressure and proportional-pressure modes are available, so plant rooms can tune response to pipework.
- Rated 7.5 kW (P2) on every main pump in the frame.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a smartphone.
- Frequency converters on the motors pair with IE5 permanent magnet motors for efficient part-load operation.
- Maximum operating pressure of 16 bar with motors sealed to IP55.
- The system protects its pumps against dry running if the incoming supply is lost.
- The system pairs two CRNE 15-8 pumps in parallel duty, controlled as a single coordinated system.
