Product Overview
Across installations such as school blocks and council facilities fed by long, pressure-hungry reticulation, the Hydro Multi-E 2 CRE 10-9 maintains stable pressure at every draw-off point. Quote part number 99614424 to have it arrive pre-configured and ready for the plant room.
Flow capacity reaches 476 L/min. Up to 130 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.
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 16.2 A. Motors are protected to IP54, while maximum system pressure is 16 bar. Liquid-temperature suitability is 5°C to 60°C. Inlet pressure is rated to 16 bar.
Its home ground covers schools and universities, hospitals and hotel plant rooms. The variable-speed system suits clean-water boosting duties with changing demand.
Features
- 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.
- Two Grundfos CRE 10-9 vertical multistage pumps run in parallel on one common base frame.
- Both constant-pressure and proportional-pressure modes are available, so plant rooms can tune response to pipework.
- The set ships with an 24L precharged diaphragm tank for low-flow stability.
- Each pump is driven by IE5 permanent magnet motors with frequency-controlled speed matching demand.
- Each main pump is rated 4 kW (P2), so per-pump draw scales down as speed follows demand.
- Maximum operating pressure of 16 bar with motors sealed to IP54.
- Dry-running protection is built into the control, protecting the pumps if the suction supply is interrupted.
- 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.
- Energy draw matches the actual job because speed follows demand, not a fixed curve.
- The stainless steel manifold assembly is supplied with two 50 mm manifold connections.
