Product Overview
Shopping centre amenities and food court ring mains maintain balanced pressure using the Hydro Multi-E 2 CRNE 64-2-1. Configured with two CRNE 64-2-1 vertical pumps in parallel, the booster dynamically matches motor speed to immediate water requirements. Everything is ordered under the single manufacturer part number 93368439.
At maximum operating frequency, the package yields up to 3400 L/min. The vertical stage assembly can build up to 74 metres of head for steep elevations. Integrated Multi-Master intelligence coordinates the pumps without requiring an external control panel, ensuring automatic role swapping and uninterrupted pressure stabilization.
Mounted on a vibration-dampened base skid, the booster incorporates stainless steel manifolds, two 150 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 39.2 A (2 x 19.6 A per pump). Motors carry IP54 sealing with maximum pressure of 10 bar. Liquid-temperature suitability is 5°C to 60°C, and inlet pressure is rated to 10 bar.
Routine plant room duty sits with mixed-use commercial buildings, corporate office towers and shopping centres, delivering seamless pressure regulation across shifts. Variable-speed motor modulation makes the set a practical clean-water pressure-boosting solution for both new plant rooms and system upgrades.
FEATURES
- Stainless steel manifolds provide two 150 mm manifold connections ready for plant pipework.
- Maximum operating pressure of 10 bar with motors sealed to IP54.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- Two Grundfos CRNE 64-2-1 vertical multistage pumps run in parallel on one common base frame.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a smartphone.
- Pumps are cut in and out according to demand, every running unit turning at the same speed to hold the pressure set point.
- The system protects its pumps against dry running if the incoming supply is lost.
- 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.
- Frequency converters on the motors pair with IE5 permanent magnet motors for efficient part-load operation.
- At P2 each main pump is 18.5 kW, covering the duty without oversizing the frame.
- Constant pressure control holds the delivered pressure flat while proportional mode lets setpoints flex with demand.
- Energy draw matches the actual job because speed follows demand, not a fixed curve.

Which total water transfer rate does this variable speed booster system displace under full duty?
At full operational capacity, the Grundfos Hydro Multi-E 2 CRNE64-2-1 U2 A-A-I-I-D (part number 93368439) supplies up to 3400 L/min total liquid throughput into pressurised pipework.
Which variable speed motor technology provides mechanical power to the pumps on this skid?
Integrated frequency converters on the Hydro Multi-E 2 CRNE64-2-1 modulate two IE5 permanent-magnet MGE electric motors rated at 18.5 kW each from a 3 x 380-415 V power supply.
Under peak elevation requirements, what total dynamic head does this booster set achieve?
Peak vertical head generated by the Hydro-Multi-E-2-CRNE64-2-1 reaches up to 74 m across distribution pipework under an 10 bar pressure envelope.
What manifold port diameters and check valve fittings connect the pumps on this booster assembly?
Parallel skid pipework on the Hydro Multi E 2 CRNE64 2 1 features DN 150 stainless steel suction and discharge headers fitted with isolating valves and discharge non-return valves.
What manufacturer warranty backing supports this packaged variable speed pump set?
Factory warranty backing on the 2 CRNE64-2-1 (Hydro Multi-E) provides an authentic Grundfos two-year manufacturer warranty protecting the complete parallel booster skid assembly.
