Product Overview
Sites such as high-occupancy towers where every level opens its taps inside the same half hour require consistent pressure regardless of demand fluctuation; the Hydro Multi-E 2 CRE45-2 achieves this with two CRE 45-2 pumps operating in parallel. Part number 93328663 provides the complete tested package in a single order line.
The system supports flow rates up to 2384 L/min. It can develop up to 76 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.
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 51.6 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 high-rise apartments, mixed-use commercial buildings and schools and universities. The control flexibility suits clean-water boosting in new installations and upgrades.
Features
- Variable speed comes from frequency converters matched to IE5 permanent magnet motors, keeping the booster set in its efficient range.
- No external controller required: Multi-Master redundancy lets either pump assume the controlling role.
- Setup and monitoring run through the Grundfos GO app rather than a panel visit.
- Each main pump is rated 15 kW (P2), so per-pump draw scales down as speed follows demand.
- Both constant-pressure and proportional-pressure modes are available, so plant rooms can tune response to pipework.
- Dry-running protection is built into the control, protecting the pumps if the suction supply is interrupted.
- The set ships with an 24L precharged diaphragm tank for low-flow stability.
- Stainless steel manifolds provide two 150 mm manifold connections ready for pipework.
- Power use precisely tracks demand, avoiding the waste of fixed-speed alternates.
- Pump staging follows demand automatically: pumps enter at low speed as pressure drops, ramp to equal speed, and exit as flow fades.
- Maximum operating pressure of 10 bar with motors sealed to IP54.
- Two Grundfos CRE 45-2 vertical multistage pumps run in parallel on one common base frame.
- The package is wet-tested and pre-configured, requiring only pipework and power on site.
