Product Overview
Tea rooms, staff kitchens and en-suite banks in small commercial sites get a constant-pressure answer in this Grundfos Hydro Multi-E 2 CRE 5-7 set. Quote part number 99657283 to have it arrive pre-configured and ready for the plant room.
Flow capacity reaches 290 L/min. Up to 68 metres of head is available to maintain pressure as demand changes. 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 4.74 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 high-rise apartments, hospitals and mixed-use commercial buildings. The control flexibility suits clean-water boosting in new installations and upgrades.
Features
- Maximum operating pressure of 10 bar with motors sealed to IP54.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- 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.
- Constant pressure control holds the delivered pressure flat while proportional mode lets setpoints flex with demand.
- Each main pump is rated 1.1 kW (P2), so per-pump draw scales down as speed follows demand.
- Two Grundfos CRE 5-7 pumps share the boosting work in parallel.
- Frequency converters on the motors pair with IE5 permanent magnet motors for efficient part-load operation.
- Stainless steel manifolds provide two 50 mm manifold connections ready for pipework.
- 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.
- Energy draw matches the actual job because speed follows demand, not a fixed curve.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
