Product Overview
High-occupancy towers where every level opens its taps inside the same half hour rely on booster systems with no tolerance for pressure variation, and the Hydro Multi-E 2 CRE64-3 is engineered for exactly that duty. Everything is ordered under the single part number 93328667.
This set provides up to 3221 L/min of flow capacity. Variable-speed operation can develop up to 130 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 150 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 87.6 A, with IP54 motor protection and a 16 bar maximum system pressure. Liquid-temperature suitability is 5°C to 60°C. Inlet pressure is rated to 16 bar.
Applications include hospitals, high-rise apartments and mixed-use commercial buildings. The control flexibility suits clean-water boosting in new installations and upgrades.
Features
- The controller tracks the pressure setpoint with proportional deviation alerts before conditions become faults.
- Rated 26 kW (P2) on every main pump in the frame.
- The system protects its pumps against dry running if the incoming supply is lost.
- No external controller required: Multi-Master redundancy lets either pump assume the controlling role.
- Power use precisely tracks demand, avoiding the waste of fixed-speed alternates.
- Rated for 16 bar system pressure; motors carry IP54 protection.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- Frequency converters on the motors pair with IE5 permanent magnet motors for efficient part-load operation.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- The stainless steel manifold assembly is supplied with two 150 mm manifold connections.
- Two Grundfos CRE 64-3 vertical multistage pumps run in parallel on one common base frame.
- Cascade logic brings pumps on-line and off-line against changing demand without manual intervention.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a phone.
