Product Overview
Commercial dairy processing suites handling sanitation rinse cycles operate the Hydro Multi-E 3 CRNE 5-7. The three-pump parallel layout shares duty evenly across the CRNE 5-7 wet ends, preserving steady pressure during morning spikes. Quote part number 99752216 to have the entire pre-commissioned assembly delivered to site.
The booster handles commercial flow volumes up to 510 L/min with ease. Up to 69 metres of shut-off head is generated to overcome vertical riser friction. 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.
Factory aligned on an engineered mounting skid, the assembly incorporates stainless steel pipework, two Rp 2 inch threaded manifold connections, isolation and non-return valves, pressure sensors, plus a 24L diaphragm tank. It connects to a 1 x 200-240 V supply at 50 / 60 Hz with combined rated current of 19.4 A (3 x 6.47 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.
The set is an ideal choice for hospital surgical wings, aged-care complexes and industrial process supply, where fluctuating tenancy water demands occur. 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 IP55.
- Stainless steel manifolds provide two Rp 2 inch threaded manifold connections ready for plant pipework.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.
- Cascade logic brings pumps on-line and off-line against changing demand without manual intervention.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- Dry-running protection is built into the control, protecting the pumps if the suction supply is interrupted.
- Energy draw matches the actual job because speed follows demand, not a fixed curve.
- Each pump is driven by IE5 permanent magnet motors with frequency-controlled speed matching demand.
- At P2 each main pump is 1.1 kW, covering the duty without oversizing the frame.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a smartphone.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- Three Grundfos CRNE 5-7 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.
