Product Overview
Commercial food cannery facilities maintaining steady process line water operate the Hydro Multi-E 3 CRNE 10-2. Integrated variable-speed drives coordinate the three CRNE 10-2 pumps in parallel, seamlessly ramping output as fixtures open. Everything is ordered under the single manufacturer part number 99752282.
Discharge delivery comfortably reaches up to 905 L/min under heavy duty. The vertical stage assembly can build up to 29 metres of head for steep elevations. Because every pump carries its own frequency converter and Multi-Master software elects the controlling pump itself, losing a control unit or pressure sensor means seamless handover rather than a shutdown.
Firmly secured on a structural base skid, the system features stainless steel manifolds, two 80 mm manifold connections, isolation and non-return valves, pressure sensors, plus a 24L diaphragm tank. It connects to a 3 x 380-415 V supply at 50 / 60 Hz with combined rated current of 7.11 A (3 x 2.37 A per pump). Motors carry IP55 sealing with maximum pressure of 10 bar. Liquid-temperature suitability is 5°C to 60°C, and inlet pressure is rated to 10 bar.
Clean-water boosting applications cover high-rise apartments, hotel plant rooms and schools and universities, where automated speed modulation is preferred. Variable-speed motor modulation makes the set a practical clean-water pressure-boosting solution for both new plant rooms and system upgrades.
FEATURES
- 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.
- Constant pressure control holds the delivered pressure flat while proportional mode lets setpoints flex with demand.
- Maximum operating pressure of 10 bar with motors sealed to IP55.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- Energy draw matches the actual job because speed follows demand, not a fixed curve.
- Pump staging follows demand automatically: pumps enter at low speed as pressure drops, ramp to equal speed, and exit as flow fades.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a smartphone.
- Three Grundfos CRNE 10-2 pumps share the boosting work in parallel.
- Stainless steel manifolds provide two 80 mm manifold connections ready for plant pipework.
- Each main pump is rated 1.1 kW (P2), so per-pump draw scales down as speed follows demand.
