Product Overview
Industrial wash-down lines and fire-ring make-up feeds running flat out rely on booster systems with no tolerance for pressure variation, and the Hydro Multi-E 3 CRE64-1-1 is engineered for exactly that duty. The complete system ships factory assembled and tested under part number 93320261.
Flow capacity reaches 4804 L/min. Up to 31 metres of head is available to maintain pressure as demand changes. Because every pump carries its own frequency converter and the Multi-Master software elects the controlling pump itself, losing a control unit or pressure sensor means seamless handover rather than a shutdown.
Factory assembled on a common base, the set combines stainless steel pipework, two 200 mm manifold connections, isolation and non-return valves, pressure sensors and a gauge, plus a 24L diaphragm tank. It connects to a 3 x 380-415 V supply at 50 / 60 Hz with a rated current of 40.9 A. Motors are protected to IP54, while maximum system pressure is 10 bar. Liquid-temperature suitability is 5°C to 60°C. Inlet pressure is rated to 10 bar.
Its home ground covers industrial process supply, aged-care complexes and schools and universities. The variable-speed system suits clean-water boosting duties with changing demand.
Features
- Rated for 10 bar system pressure; motors carry IP54 protection.
- Stainless steel manifolds provide two 200 mm manifold connections ready for pipework.
- The package is wet-tested and pre-configured, requiring only pipework and power on site.
- Power use precisely tracks demand, avoiding the waste of fixed-speed alternates.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a phone.
- Both constant-pressure and proportional-pressure modes are available, so plant rooms can tune response to pipework.
- Cascade logic brings pumps on-line and off-line against changing demand without manual intervention.
- The system protects its pumps against dry running if the incoming supply is lost.
- Variable speed comes from frequency converters matched to IE5 permanent magnet motors, keeping the booster set in its efficient range.
- Three Grundfos CRE 64-1 pumps share the boosting work in parallel.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- Rated 5.5 kW (P2) on every main pump in the frame.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.

How much water transfer volume can this packaged booster assembly maintain across peak usage cycles?
Operating across its factory curve, the Grundfos Hydro Multi-E 3 CRE64-1-1 U2 A-A-I-I-DU discharges up to 4804 L/min of clean water to maintain consistent line pressure during peak demand cycles.
How are the multistage centrifugal pumps driven and speed regulated across shifting water draw?
Each centrifugal stage of the Hydro Multi-E 3 CRE64-1-1 is driven by a 5.5 kW IE5 permanent-magnet MGE electric motor running on 3 x 380-415 V power, utilizing built-in variable speed drives to adjust output dynamically.
Which total dynamic lift head does this variable speed booster assembly achieve under full duty?
Elevating water across multi-level pipework, the Hydro-Multi-E-3-CRE64-1-1 maintains up to 31 m total dynamic head with an overall 10 bar maximum operating limit.
Which pipework connection fittings and manifold components are factory mounted to the skid?
Plumbed for rapid site installation, the Hydro Multi E 3 CRE64 1 1 includes DN 200 stainless steel headers equipped with dedicated isolating valves, check valves, and pressure transmitters.
How is this multi pump booster package protected by manufacturer warranty provisions?
Grundfos provides two-year manufacturer warranty coverage on the 3 CRE64-1-1 (Hydro Multi-E), securing the complete multi-pump package, manifolds, and integrated electronics.
