Product Overview
Commercial dry-cleaning and garment finishing hubs maintain process water with the Hydro Multi-E 3 CRNE 10-2. Operating three CRNE 10-2 pumps in parallel duty, the booster automatically cuts pumps in and out to track line velocity. Ordering part number 99752271 puts the fully tested booster skid directly onto the plant room floor.
Discharge rates scale up to 905 L/min to satisfy simultaneous showers. Up to 29 metres of delivery head is available to keep upper-floor fixtures pressurised. Advanced Multi-Master firmware shares operating duties directly between pump heads, providing immediate fail-safe handover if an individual drive is isolated.
Pre-assembled on a vibration-isolated steel base, the booster combines 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 13.5 A (3 x 4.5 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.
Designed for institutional and commercial duty across food production facilities, logistics distribution hubs and aquatic sports centres, the system ensures long service life. Variable-speed motor modulation makes the set a practical clean-water pressure-boosting solution for both new plant rooms and system upgrades.
FEATURES
- The system protects its pumps against dry running if the incoming supply is lost.
- Stainless steel manifolds provide two 80 mm manifold connections ready for plant pipework.
- Frequency converters on the motors pair with IE5 permanent magnet motors for efficient part-load operation.
- Both constant-pressure and proportional-pressure modes are available, so plant rooms can tune response to pipework.
- Pump staging follows demand automatically: pumps enter at low speed as pressure drops, ramp to equal speed, and exit as flow fades.
- 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.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a smartphone.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- Three Grundfos CRNE 10-2 pumps share the boosting work in parallel.
- Maximum operating pressure of 10 bar with motors sealed to IP55.
- Rated 0.75 kW (P2) on every main pump in the frame.

How does the integrated variable frequency drive regulate motor speed across changing flow rates?
Speed-controlled electric drive on the Grundfos Hydro Multi-E 3 CRNE 10-2 U8 A-A-I-I-DU (part number 99752271) delivers power through three IE5 permanent-magnet MGE electric motors rated at 0.75 kW each on 1 x 200-240 V mains.
Under full operational pressure, what dynamic head does this parallel booster assembly deliver?
Pressure boosting performance allows the Hydro Multi-E 3 CRNE 10-2 to achieve up to 29 m dynamic elevation head and an 10 bar working envelope.
Which pipework connection sizing and manifold valves are integrated across this booster unit?
Common manifolding across the Hydro-Multi-E-3-CRNE-10-2 utilizes DN 80 stainless steel suction and discharge pipework with integrated non-return valves and isolating ball valves.
What warranty coverage and service provisions back this multi-pump booster unit?
