Product Overview
Where residential towers and medium commercial sites outgrowing their mains pressure are served from a single booster, the Hydro Multi-E 3 CRE 10-5 holds pressure steady as three CRE 10-5 pumps respond to changing flow. Part number 99614414 provides the complete tested package in a single order line.
It handles flows up to 714 L/min across the system. The pumps can develop up to 71 metres of head when pressure demand increases. 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.
For installation, the booster is supplied pre-assembled with stainless steel manifolds, two 80 mm manifold connections, isolation valves, non-return valves, pressure sensors and a gauge, plus a 24L diaphragm tank. It is designed for 3 x 380-415 V power at 50 / 60 Hz with a rated current of 13.3 A, with IP54 motor protection and a 10 bar maximum system pressure. Liquid-temperature suitability is 5°C to 60°C. Inlet pressure is rated to 10 bar.
Applications include hospitals, mixed-use commercial buildings and schools and universities. The control flexibility suits clean-water boosting in new installations and upgrades.
Features
- Cascade logic brings pumps on-line and off-line against changing demand without manual intervention.
- Rated 2.2 kW (P2) on every main pump in the frame.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.
- Energy draw matches the actual job because speed follows demand, not a fixed curve.
- The set ships with an 24L precharged diaphragm tank for low-flow stability.
- Each pump is driven by IE5 permanent magnet motors with frequency-controlled speed matching demand.
- Stainless steel manifolds provide two 80 mm manifold connections ready for pipework.
- Dry-running protection is built into the control, protecting the pumps if the suction supply is interrupted.
- The controller tracks the pressure setpoint with proportional deviation alerts before conditions become faults.
- Three Grundfos CRE 10-5 pumps share the boosting work in parallel.
- Setup and monitoring run through the Grundfos GO app rather than a panel visit.
- Rated for 10 bar system pressure; motors carry IP54 protection.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
