Product Overview
In small sites where a duty-point review calls for reserve pump capacity, the simultaneous demand of the morning peak places heavy loads on the supply; the Hydro Multi-E 3 CRE 5-2 answers with three CRE 5-2 pumps operating in parallel. One factory-tested package replaces a shelf of loose components; order part number 99614225 to put it on site.
This set provides up to 446 L/min of flow capacity. Variable-speed operation can develop up to 19 metres of head where required. 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 50 mm manifold connections, isolation valves, non-return valves, pressure sensors and a gauge, plus a 24L diaphragm tank. It is designed for 1 x 200-240 V power at 50 / 60 Hz with a rated current of 7.17 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.
Expect it on hotel plant rooms and schools and universities sites, plus aged-care complexes duties. It provides clean-water pressure boosting for both new plant rooms and refits.
Features
- Maximum operating pressure of 10 bar with motors sealed to IP54.
- Both constant-pressure and proportional-pressure modes are available, so plant rooms can tune response to pipework.
- The system protects its pumps against dry running if the incoming supply is lost.
- Rated 0.37 kW (P2) on every main pump in the frame.
- Frequency converters on the motors pair with IE5 permanent magnet motors for efficient part-load operation.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- The stainless steel manifold assembly is supplied with two 50 mm manifold connections.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a phone.
- No external controller required: Multi-Master redundancy lets either pump assume the controlling role.
- The system pairs three CRE 5-2 pumps in parallel duty, controlled as a single coordinated system.
- Energy draw matches the actual job because speed follows demand, not a fixed curve.
- Pumps are cut in and out according to demand, every running unit turning at the same speed to hold the pressure set point.
