Product Overview
Holiday units and boutique apartment blocks juggling showers at the morning peak get a constant-pressure answer in this Grundfos Hydro Multi-E 3 CRE 5-2 set. One factory-tested package replaces a shelf of loose components; order part number 99614325 to put it on site.
The system supports flow rates up to 504 L/min. It can develop up to 19 metres of head for dependable pressure boosting. 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 4.41 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.
Applications include schools and universities, hospitals and industrial process supply. The control flexibility suits clean-water boosting in new installations and upgrades.
Features
- Maximum operating pressure of 10 bar with motors sealed to IP54.
- Slow-speed duty and staged switching keep consumption down through low-demand hours.
- The package is wet-tested and pre-configured, requiring only pipework and power on site.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.
- The stainless steel manifold assembly is supplied with two 50 mm manifold connections.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- Each pump is driven by IE5 permanent magnet motors with frequency-controlled speed matching demand.
- Cascade logic brings pumps on-line and off-line against changing demand without manual intervention.
- Rated 0.55 kW (P2) on every main pump in the frame.
- The controller tracks the pressure setpoint with proportional deviation alerts before conditions become faults.
- Dry-running protection is built into the control, protecting the pumps if the suction supply is interrupted.
- Setup and monitoring run through the Grundfos GO app rather than a panel visit.
- Three Grundfos CRE 5-2 pumps share the boosting work in parallel.
