Product Overview
Large-scale distribution centres and logistics hubs running wash pads count on the robust Hydro Multi-E 2 CRNE 64-3-2. Staged parallel operation between two CRNE 64-3-2 pumps maintains consistent line pressure without erratic cycling. Ordering part number 93368447 puts the fully tested booster skid directly onto the plant room floor.
Providing up to 3400 L/min of clean-water volumetric flow, Up to 101.1 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.
Constructed as a turnkey plant room unit, the assembly combines stainless steel pipework, 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 87.6 A (2 x 43.8 A per pump). Motors carry IP54 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 booster provides dedicated clean-water service for food production facilities, logistics distribution hubs and aquatic sports centres, keeping line velocity steady. Variable-speed motor modulation makes the set a practical clean-water pressure-boosting solution for both new plant rooms and system upgrades.
FEATURES
- Rated 22 kW (P2) on every main pump in the frame.
- Stainless steel manifolds provide two 150 mm manifold connections ready for plant pipework.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a smartphone.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- The system protects its pumps against dry running if the incoming supply is lost.
- Maximum operating pressure of 16 bar with motors sealed to IP54.
- Constant pressure control holds the delivered pressure flat while proportional mode lets setpoints flex with demand.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- The system pairs two CRNE 64-3-2 pumps in parallel duty, controlled as a single coordinated system.
- 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.
- Variable speed comes from frequency converters matched to IE5 permanent magnet motors, keeping the booster set in its efficient range.
