Product Overview
Maritime terminal offices and dockside amenities operate dependable boosting via the Hydro Multi-E 3 CRE 45-3. Operating three CRE 45-3 pumps in parallel duty, the booster automatically cuts pumps in and out to track line velocity. Ordering part number 93320253 puts the fully tested booster skid directly onto the plant room floor.
Discharge flow expands smoothly up to 3500 L/min to meet fixture demand. Up to 111.2 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 on a rigid fabricated baseplate, the booster features stainless steel pipework, two 200 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 96 A (3 x 32 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 set provides robust, constant pressure for food production facilities, logistics distribution hubs and aquatic sports centres, protecting delicate wash systems. 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 pairs three CRE 45-3 pumps in parallel duty, controlled as a single coordinated system.
- Cascade logic brings pumps on-line and off-line against changing demand without manual intervention.
- 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.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a smartphone.
- Maximum operating pressure of 16 bar with motors sealed to IP54.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.
- At P2 each main pump is 18.5 kW, covering the duty without oversizing the frame.
- Power use precisely tracks demand, avoiding the waste of fixed-speed alternates.
- The system protects its pumps against dry running if the incoming supply is lost.
- Stainless steel manifolds provide two 200 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.
