Product Overview
Mixed-use buildings where a single booster covers retail, offices and apartments rely on booster systems with no tolerance for pressure variation, and the Hydro Multi-E 3 CRE 15-1 is engineered for exactly that duty. The complete system ships factory assembled and tested under part number 99657290.
Flow capacity reaches 1297 L/min. Up to 19 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.
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 7.11 A. The motors have IP54 protection and the system is rated to 10 bar maximum pressure. Liquid-temperature suitability is 5°C to 60°C. Inlet pressure is rated to 10 bar.
Typical duty sits with schools and universities, mixed-use commercial buildings and industrial process supply. It is designed for clean-water pressure boosting where demand varies through the day.
Features
- Slow-speed duty and staged switching keep consumption down through low-demand hours.
- The stainless steel manifold assembly is supplied with two 100 mm manifold connections.
- The package is wet-tested and pre-configured, requiring only pipework and power on site.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a phone.
- Maximum operating pressure of 10 bar with motors sealed to IP54.
- Three Grundfos CRE 15-1 vertical multistage pumps run in parallel on one common base frame.
- Variable speed comes from frequency converters matched to IE5 permanent magnet motors, keeping the booster set in its efficient range.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- At P2 each main pump is 1.1 kW, covering the duty without oversizing the frame.
- Both constant-pressure and proportional-pressure modes are available, so plant rooms can tune response to pipework.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.
- Cascade logic brings pumps on-line and off-line against changing demand without manual intervention.
- Dry-running protection is built into the control, protecting the pumps if the suction supply is interrupted.

What peak fluid volume does this variable speed booster set deliver during high draw periods?
Operating across its factory curve, the Grundfos Hydro Multi-E 3 CRE 15-1 U2 A-A-I-I-DU discharges up to 1297 L/min of clean water to maintain consistent line pressure during peak demand cycles.
What electrical motor power and drive electronics operate the pumps on this booster assembly?
Each centrifugal stage of the Hydro Multi-E 3 CRE 15-1 is driven by a 1.1 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.
What maximum system operating pressure and dynamic head does this packaged booster set deliver?
Elevating water across multi-level pipework, the Hydro-Multi-E-3-CRE-15-1 maintains up to 19 m total dynamic head with an overall 10 bar maximum operating limit.
Which suction and discharge manifold connections and isolation valves are integrated onto the skid?
Plumbed for rapid site installation, the Hydro Multi E 3 CRE 15 1 includes DN 100 stainless steel headers equipped with dedicated isolating valves, check valves, and pressure transmitters.
