Product Overview
For apartment towers, hotel plant rooms and school wings with real morning demand spikes, a factory-assembled Hydro Multi-E 2 CRE45-3 package provides a well-matched solution, with two CRE 45-3 pumps staged against the demand curve. Specify part number 93320252 and the whole set lands tested, assembled and ready for pipework.
Flow capacity reaches 2367 L/min. Up to 113 metres of head is available to maintain pressure as demand changes. Because every pump carries its own frequency converter and the Multi-Master software elects the controlling pump itself, losing a control unit or pressure sensor means seamless handover rather than a shutdown.
Factory assembled on a common base, the set combines stainless steel pipework, two 150 mm manifold connections, isolation and non-return valves, pressure sensors and a gauge, plus a 24L diaphragm tank. It connects to a 3 x 380-415 V supply at 50 / 60 Hz with a rated current of 64 A. Motors are protected to IP54, while maximum system pressure is 16 bar. Liquid-temperature suitability is 5°C to 60°C. Inlet pressure is rated to 16 bar.
Typical duty sits with high-rise apartments, hotel plant rooms and hospitals. It is designed for clean-water pressure boosting where demand varies through the day.
Features
- Energy draw matches the actual job because speed follows demand, not a fixed curve.
- Rated for 16 bar system pressure; motors carry IP54 protection.
- 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.
- Each pump is driven by IE5 permanent magnet motors with frequency-controlled speed matching demand.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- The system protects its pumps against dry running if the incoming supply is lost.
- The controller tracks the pressure setpoint with proportional deviation alerts before conditions become faults.
- The stainless steel manifold assembly is supplied with two 150 mm manifold connections.
- Pumps are cut in and out according to demand, every running unit turning at the same speed to hold the pressure set point.
- The system pairs two CRE 45-3 pumps in parallel duty, controlled as a single coordinated system.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a phone.
- Each main pump is rated 18.5 kW (P2), so per-pump draw scales down as speed follows demand.

Under peak consumption conditions, what water volume does this packaged booster set deliver?
Operating across its factory curve, the Grundfos Hydro Multi-E 2 CRE45-3 U2 A-A-I-I-D discharges up to 2367 L/min of clean water to maintain consistent line pressure during peak demand cycles.
How are the parallel centrifugal pumps powered and speed regulated across variable flow demands?
Each centrifugal stage of the Hydro Multi-E 2 CRE45-3 is driven by a 18.5 kW IE5 permanent-magnet MGE electric motor running on 3 x 380-415 V power, utilizing built-in variable speed drives to adjust output dynamically.
How much total dynamic elevation head does this parallel centrifugal booster assembly deliver?
Elevating water across multi-level pipework, the Hydro-Multi-E-2-CRE45-3 maintains up to 113 m total dynamic head with an overall 16 bar maximum operating limit.
Which manifold connection sizes and isolation valves are supplied on this packaged booster skid?
Plumbed for rapid site installation, the Hydro Multi E 2 CRE45 3 includes DN 150 stainless steel headers equipped with dedicated isolating valves, check valves, and pressure transmitters.
What factory warranty period and support terms cover this multi pump booster unit?
Grundfos provides two-year manufacturer warranty coverage on the 2 CRE45-3 (Hydro Multi-E), securing the complete multi-pump package, manifolds, and integrated electronics.
