Product Overview
Commercial kitchen commissaries preparing bulk catering meals choose the Hydro Multi-E 3 CRE 45-1. Staged parallel operation between three CRE 45-1 pumps maintains consistent line pressure without erratic cycling. Quote part number 93320247 to have the entire pre-commissioned assembly delivered to site.
Volumetric supply reaches up to 3500 L/min to protect pipework pressure. Up to 38.6 metres of shut-off head is generated to overcome vertical riser friction. Advanced Multi-Master firmware shares operating duties directly between pump heads, providing immediate fail-safe handover if an individual drive is isolated.
Engineered on a heavy-duty structural frame, the package 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 40.9 A (3 x 13.63 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.
Clean-water distribution duties cover food production facilities, logistics distribution hubs and aquatic sports centres, where automated multi-pump staging is required. Variable-speed motor modulation makes the set a practical clean-water pressure-boosting solution for both new plant rooms and system upgrades.
FEATURES
- Maximum operating pressure of 10 bar with motors sealed to IP54.
- Rated 5.5 kW (P2) on every main pump in the frame.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- The controller tracks the pressure setpoint with proportional deviation alerts before conditions become faults.
- Energy draw matches the actual job because speed follows demand, not a fixed curve.
- Stainless steel manifolds provide two 200 mm manifold connections ready for plant pipework.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a smartphone.
- The system pairs three CRE 45-1 pumps in parallel duty, controlled as a single coordinated system.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- Variable speed comes from frequency converters matched to IE5 permanent magnet motors, keeping the booster set in its efficient range.
- 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.
- Pumps are cut in and out according to demand, every running unit turning at the same speed to hold the pressure set point.

What plumbing manifold connections and non-return check valves are installed on this booster skid?
Hydraulic header plumbing across the Grundfos Hydro Multi-E 3 CRE45-1 U2 A-A-I-I-DU (part number 93320247) incorporates DN 200 stainless steel suction and discharge manifolds with built-in non-return valves and isolating valves.
What manufacturer warranty period covers the pumps and electronic drive package?
Long-term operational backing for the Hydro Multi-E 3 CRE45-1 includes an authentic Grundfos two-year manufacturer warranty covering the parallel pumps, manifolds, and skid frame.
Which maximum volumetric delivery does this packaged booster system provide for distribution headers?
Parallel pump operation enables the Hydro-Multi-E-3-CRE45-1 to discharge a peak water volume of 3500 L/min into header pipework.
How are the centrifugal pumps driven and inverter regulated across variable network demands?
Propulsion across the Hydro Multi E 3 CRE45 1 is supplied by three IE5 permanent-magnet MGE electric motors rated at 5.5 kW each on a 3 x 380-415 V electrical supply.
Under full discharge duty, what maximum elevation head does this packaged booster skid maintain?
Elevating water across multi-level pipework, the 3 CRE45-1 (Hydro Multi-E) maintains up to 38.6 m total dynamic head with an overall 10 bar operating limit.
