Product Overview
Automotive service centres and heavy vehicle wash bays depend on the Hydro Multi-E 3 CRE 45-4. Three Grundfos CRE 45-4 multistage pumps share the hydraulic load across a common skid, staging smoothly to match real-time draw. Quote part number 93320255 to have the entire pre-commissioned assembly delivered to site.
Total manifold throughput reaches up to 3500 L/min under heavy draw. Up to 150.6 metres of shut-off head is generated to overcome vertical riser friction. 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.
Pre-assembled on a heavy-gauge channel base, the package brings together 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 132 A (3 x 44 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.
Installation environments routinely include hospital surgical wings, aged-care complexes and industrial process supply, where water usage shifts throughout the day. Variable-speed motor modulation makes the set a practical clean-water pressure-boosting solution for both new plant rooms and system upgrades.
FEATURES
- Power use precisely tracks demand, avoiding the waste of fixed-speed alternates.
- The system pairs three CRE 45-4 pumps in parallel duty, controlled as a single coordinated system.
- The system protects its pumps against dry running if the incoming supply is lost.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- Maximum operating pressure of 16 bar with motors sealed to IP54.
- Both constant-pressure and proportional-pressure modes are available, so plant rooms can tune response to pipework.
- Stainless steel manifolds provide two 200 mm manifold connections ready for plant pipework.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- 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.
- Cascade logic brings pumps on-line and off-line against changing demand without manual intervention.
- Each pump is driven by IE5 permanent magnet motors with frequency-controlled speed matching demand.
- Rated 26 kW (P2) on every main pump in the frame.
