Product Overview
Across installations such as small sites where a duty-point review calls for reserve pump capacity, the Hydro Multi-E 2 CRE 5-8 maintains stable pressure at every draw-off point. Specify part number 99614276 and the whole set lands tested, assembled and ready for pipework.
The system supports flow rates up to 307 L/min. It can develop up to 78 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 two-pump package arrives as one base-mounted assembly with stainless steel manifolds, two 50 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 6.2 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.
Applications include industrial process supply, aged-care complexes and high-rise apartments. The control flexibility suits clean-water boosting in new installations and upgrades.
Features
- Each pump is driven by IE5 permanent magnet motors with frequency-controlled speed matching demand.
- Dry-running protection is built into the control, protecting the pumps if the suction supply is interrupted.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- Stainless steel manifolds provide two 50 mm manifold connections ready for pipework.
- Slow-speed duty and staged switching keep consumption down through low-demand hours.
- Maximum operating pressure of 10 bar with motors sealed to IP54.
- No external controller required: Multi-Master redundancy lets either pump assume the controlling role.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a phone.
- Each main pump is rated 1.5 kW (P2), so per-pump draw scales down as speed follows demand.
- Cascade logic brings pumps on-line and off-line against changing demand without manual intervention.
- Two Grundfos CRE 5-8 pumps share the boosting work in parallel.
- Constant pressure control holds the delivered pressure flat while proportional mode lets setpoints flex with demand.

Under maximum water demand, what delivery flow volume can this multi pump package maintain?
Operating across its factory curve, the Grundfos Hydro Multi-E 2 CRE 5-8 U2 A-A-I-I-DU discharges up to 307 L/min of clean water to maintain consistent line pressure during peak demand cycles.
What electric motor power and supply voltage powers each pump in this packaged booster set?
Each centrifugal stage of the Hydro Multi-E 2 CRE 5-8 is driven by a 1.5 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 system working pressure and maximum vertical head does this multi stage booster unit produce?
Elevating water across multi-level pipework, the Hydro-Multi-E-2-CRE-5-8 maintains up to 78 m total dynamic head with an overall 10 bar maximum operating limit.
How are the parallel centrifugal stages connected to common suction and discharge manifolds?
Plumbed for rapid site installation, the Hydro Multi E 2 CRE 5 8 includes R 2 stainless steel headers equipped with dedicated isolating valves, check valves, and pressure transmitters.
How is this multi stage booster skid protected under manufacturer warranty terms?
