Product Overview
Civil civic buildings and council works depots ensure dependable plant room boosting with the Hydro Multi-E 2 CRNE 32-4-2. The package operates two Grundfos CRNE 32-4-2 vertical multistage pumps in parallel, automatically staging each unit as flow demand increases. Everything is ordered under the single manufacturer part number 93368411.
Discharge volume scales up to 1600 L/min across multi-branch distribution. The vertical stage assembly can build up to 101.9 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.
Supplied as an integrated skid-mounted package, the booster features stainless steel manifolds, two 100 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 39.2 A (2 x 19.6 A per pump). Motors carry IP54 sealing with maximum pressure of 16 bar. Liquid-temperature suitability is 5°C to 60°C, and inlet pressure is rated to 16 bar.
Building services consultants specify the set across high-rise apartments, hotel plant rooms and schools and universities for turnkey pressure duty. Variable-speed motor modulation makes the set a practical clean-water pressure-boosting solution for both new plant rooms and system upgrades.
FEATURES
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- Rated 7.5 kW (P2) on every main pump in the frame.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.
- Pump staging follows demand automatically: pumps enter at low speed as pressure drops, ramp to equal speed, and exit as flow fades.
- The controller tracks the pressure setpoint with proportional deviation alerts before conditions become faults.
- Frequency converters on the motors pair with IE5 permanent magnet motors for efficient part-load operation.
- Dry-running protection is built into the control, protecting the pumps if the suction supply is interrupted.
- The system pairs two CRNE 32-4-2 pumps in parallel duty, controlled as a single coordinated system.
- Slow-speed duty and staged switching keep consumption down through low-demand hours.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a smartphone.
- Stainless steel manifolds provide two 100 mm manifold connections ready for plant pipework.
- Maximum operating pressure of 16 bar with motors sealed to IP54.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
