Product Overview
Pharmaceutical packing facilities requiring clean-water process pressure choose the Hydro Multi-E 2 CRNE 45-3. Two Grundfos CRNE 45-3 multistage pumps share the hydraulic load across a common skid, staging smoothly to match real-time draw. Quote part number 93368427 to have the entire pre-commissioned assembly delivered to site.
Throughput capacity scales smoothly up to 2333 L/min as fixtures open. Up to 111.2 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.
Supplied as a fully piped booster assembly, the set integrates 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 64 A (2 x 32 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.
Its home ground covers facilities like hospital surgical wings, aged-care complexes and industrial process supply, where line pressure must remain uncompromised. Variable-speed motor modulation makes the set a practical clean-water pressure-boosting solution for both new plant rooms and system upgrades.
FEATURES
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a smartphone.
- Slow-speed duty and staged switching keep consumption down through low-demand hours.
- The system pairs two CRNE 45-3 pumps in parallel duty, controlled as a single coordinated system.
- Each pump is driven by IE5 permanent magnet motors with frequency-controlled speed matching demand.
- Both constant-pressure and proportional-pressure modes are available, so plant rooms can tune response to pipework.
- The system protects its pumps against dry running if the incoming supply is lost.
- Maximum operating pressure of 16 bar with motors sealed to IP54.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.
- Rated 18.5 kW (P2) on every main pump in the frame.
- Pump staging follows demand automatically: pumps enter at low speed as pressure drops, ramp to equal speed, and exit as flow fades.
- Stainless steel manifolds provide two 150 mm manifold connections ready for plant pipework.

How much fluid volume can the parallel centrifugal wet ends discharge when operating together?
When all pumps run simultaneously, the Grundfos Hydro Multi-E 2 CRNE45-3 U2 A-A-I-I-D (part number 93368427) maintains a total delivery throughput of up to 2333 L/min.
Which permanent magnet or inverter electric motors power this parallel pump assembly?
Mechanical propulsion across the Hydro Multi-E 2 CRNE45-3 relies on two 18.5 kW IE5 permanent-magnet MGE electric motors running on a 3 x 380-415 V mains feed.
How much total dynamic head does this multi-pump booster package generate under peak demand?
Vertical discharge capability on the Hydro-Multi-E-2-CRNE45-3 supplies up to 111.2 m dynamic elevation head while maintaining 16 bar pressure tolerance.
What plumbing manifold dimensions and isolating valves are factory assembled on this package?
Piping infrastructure across the Hydro Multi E 2 CRNE45 3 supplies factory-fitted DN 150 stainless steel suction and discharge headers with line check valves and isolating valves.
