Product Overview
Where school blocks and council facilities fed by long, pressure-hungry reticulation are served from a single booster, the Hydro Multi-E 3 CRE 15-5 holds pressure steady as three CRE 15-5 pumps respond to changing flow. Specify part number 99614460 and the whole set lands tested, assembled and ready for pipework.
The system supports flow rates up to 1322 L/min. It can develop up to 99 metres of head for dependable pressure boosting. 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.
The three-pump package arrives as one base-mounted assembly with stainless steel manifolds, two 100 mm manifold connections, valves, sensors and a pressure gauge, plus a 24L diaphragm tank. Electrical supply is 3 x 380-415 V at 50 / 60 Hz with a rated current of 32.9 A. The motors have IP54 protection and the system is rated to 16 bar maximum pressure. Liquid-temperature suitability is 5°C to 60°C. Inlet pressure is rated to 16 bar.
Typical duty sits with hotel plant rooms, high-rise apartments and hospitals. It is designed for clean-water pressure boosting where demand varies through the day.
Features
- Each main pump is rated 5.5 kW (P2), so per-pump draw scales down as speed follows demand.
- The stainless steel manifold assembly is supplied with two 100 mm manifold connections.
- No external controller required: Multi-Master redundancy lets either pump assume the controlling role.
- Dry-running protection is built into the control, protecting the pumps if the suction supply is interrupted.
- Power use precisely tracks demand, avoiding the waste of fixed-speed alternates.
- Pump staging follows demand automatically: pumps enter at low speed as pressure drops, ramp to equal speed, and exit as flow fades.
- The package is wet-tested and pre-configured, requiring only pipework and power on site.
- Each pump is driven by IE5 permanent magnet motors with frequency-controlled speed matching demand.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- 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.
- Setup and monitoring run through the Grundfos GO app rather than a panel visit.
- Three Grundfos CRE 15-5 vertical multistage pumps run in parallel on one common base frame.

Under maximum flow conditions, what water delivery volume can this parallel pump unit maintain?
Operating across its factory curve, the Grundfos Hydro Multi-E 3 CRE 15-5 U2 A-A-I-I-DU discharges up to 1322 L/min of clean water to maintain consistent line pressure during peak demand cycles.
How is variable frequency motor propulsion delivered to each centrifugal wet end on this unit?
Each centrifugal stage of the Hydro Multi-E 3 CRE 15-5 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.
How much elevation lift head does this multi pump booster system generate across the ringmain?
Elevating water across multi-level pipework, the Hydro-Multi-E-3-CRE-15-5 maintains up to 99 m total dynamic head with an overall 16 bar maximum operating limit.
What plumbing connections and manifold valve hardware are provided across the booster framework?
Plumbed for rapid site installation, the Hydro Multi E 3 CRE 15 5 includes DN 100 stainless steel headers equipped with dedicated isolating valves, check valves, and pressure transmitters.
What manufacturer warranty terms apply to this factory assembled booster skid?
Grundfos provides two-year manufacturer warranty coverage on the 3 CRE 15-5 (Hydro Multi-E), securing the complete multi-pump package, manifolds, and integrated electronics.
