Product Overview
For tea rooms, staff kitchens and en-suite banks in small commercial sites, a factory-assembled Hydro Multi-E 3 CRE 3-4 package provides a well-matched solution, with three CRE 3-4 pumps staged against the demand curve. Quote part number 99614239 to have it arrive pre-configured and ready for the plant room.
Flow capacity reaches 232 L/min. Up to 37 metres of head is available to maintain pressure as demand changes. 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.
Factory assembled on a common base, the set combines stainless steel pipework, two 50 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 3.42 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.
Expect it on industrial process supply and schools and universities sites, plus high-rise apartments duties. It provides clean-water pressure boosting for both new plant rooms and refits.
Features
- Power use precisely tracks demand, avoiding the waste of fixed-speed alternates.
- Frequency converters on the motors pair with IE5 permanent magnet motors for efficient part-load operation.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- Setup and monitoring run through the Grundfos GO app rather than a panel visit.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- Three Grundfos CRE 3-4 pumps share the boosting work in parallel.
- Maximum operating pressure of 10 bar with motors sealed to IP54.
- The stainless steel manifold assembly is supplied with two 50 mm manifold connections.
- The system protects its pumps against dry running if the incoming supply is lost.
- Rated 0.37 kW (P2) on every main pump in the frame.
- No external controller required: Multi-Master redundancy lets either pump assume the controlling role.
- Constant pressure control holds the delivered pressure flat while proportional mode lets setpoints flex with demand.
- Pumps are cut in and out according to demand, every running unit turning at the same speed to hold the pressure set point.

What motor propulsion and electronic speed control system drives this multi pump booster skid?
Electronic speed regulation across the Grundfos Hydro Multi-E 3 CRE 3-4 U2 A-A-I-I-DU is provided by three IE5 permanent-magnet MGE electric motors rated at 0.37 kW apiece on 3 x 380-415 V power, modulating motor rpm according to demand.
Under peak network pressure requirements, what dynamic head does this booster unit maintain?
Hydraulic elevation capability on the Hydro Multi-E 3 CRE 3-4 generates up to 37 m total dynamic head while supporting a maximum operating pressure rating of 10 bar.
How are the common suction and discharge headers arranged across the parallel pump set?
Common manifolding across the Hydro-Multi-E-3-CRE-3-4 utilizes R 2 stainless steel suction and discharge pipework with integrated non-return valves and isolating ball valves.
What warranty coverage backs this complete factory assembled booster assembly?
Investment protection for the Hydro Multi E 3 CRE 3 4 features a genuine Grundfos two-year manufacturer warranty supported by nationwide technical service and replacement components.
Which total water transfer rate does this variable speed booster system displace under full duty?
For high-demand distribution pipework, the 3 CRE 3-4 (Hydro Multi-E) delivers a peak water displacement rate of 232 L/min across its parallel multistage pump assembly.
