Product Overview
Where school blocks and council facilities fed by long, pressure-hungry reticulation are served from a single booster, the Hydro Multi-E 3 CRE 10-1 holds pressure steady as three CRE 10-1 pumps respond to changing flow. Part number 99614379 provides the complete tested package in a single order line.
Flow capacity reaches 767 L/min. Up to 14 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.
For installation, the booster is supplied pre-assembled with stainless steel manifolds, two 80 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 4.41 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.
Typical duty sits with industrial process supply, high-rise apartments and hotel plant rooms. It is designed for clean-water pressure boosting where demand varies through the day.
Features
- Each main pump is rated 0.55 kW (P2), so per-pump draw scales down as speed follows demand.
- Three Grundfos CRE 10-1 pumps share the boosting work in parallel.
- Both constant-pressure and proportional-pressure modes are available, so plant rooms can tune response to pipework.
- The package is wet-tested and pre-configured, requiring only pipework and power on site.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a phone.
- The set ships with an 24L precharged diaphragm tank for low-flow stability.
- Dry-running protection is built into the control, protecting the pumps if the suction supply is interrupted.
- Each pump is driven by IE5 permanent magnet motors with frequency-controlled speed matching demand.
- Pump staging follows demand automatically: pumps enter at low speed as pressure drops, ramp to equal speed, and exit as flow fades.
- Power use precisely tracks demand, avoiding the waste of fixed-speed alternates.
- The stainless steel manifold assembly is supplied with two 80 mm manifold connections.
- Rated for 10 bar system pressure; motors carry IP54 protection.
- No external controller required: Multi-Master redundancy lets either pump assume the controlling role.
