Product Overview
Multi-storey car wash facilities needing non-stop volumetric delivery install the Hydro Multi-E 2 CRNE 45-1. The two-pump parallel layout shares duty evenly across the CRNE 45-1 wet ends, preserving steady pressure during morning spikes. The complete booster system ships factory assembled and certified under part number 93368417.
Continuous discharge capacity reaches up to 2333 L/min across the building. Line pressure is maintained with up to 38.6 metres of maximum delivery head. 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.
Pre-built on a rigid floor-mounted base, the booster combines stainless steel pipework, two 150 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 19.9 A (2 x 9.95 A per pump). Motors carry IP54 sealing with maximum pressure of 10 bar. Liquid-temperature suitability is 5°C to 60°C, and inlet pressure is rated to 10 bar.
Facility managers rely on the package across hospital surgical wings, aged-care complexes and industrial process supply for unattended, reliable booster duty. Variable-speed motor modulation makes the set a practical clean-water pressure-boosting solution for both new plant rooms and system upgrades.
FEATURES
- Maximum operating pressure of 10 bar with motors sealed to IP54.
- Power use precisely tracks demand, avoiding the waste of fixed-speed alternates.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- Two Grundfos CRNE 45-1 pumps share the boosting work in parallel.
- Cascade logic brings pumps on-line and off-line against changing demand without manual intervention.
- Frequency converters on the motors pair with IE5 permanent magnet motors for efficient part-load operation.
- Both constant-pressure and proportional-pressure modes are available, so plant rooms can tune response to pipework.
- Each main pump is rated 5.5 kW (P2), so per-pump draw scales down as speed follows demand.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a smartphone.
- Dry-running protection is built into the control, protecting the pumps if the suction supply is interrupted.
- 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.
- Stainless steel manifolds provide two 150 mm manifold connections ready for plant pipework.
