Product Overview
Civic buildings and government administrative facilities ensure dependable booster duty with the Grundfos Hydro Multi-E 3 x CRNE32-1-1 Three Phase 3 x 1.5kW Variable Speed Booster Pump Set with 24L Tank. Three Grundfos CRNE32-1-1 multistage pumps work in unison to eliminate pressure fluctuations during heavy usage. Part number 93368408 provides the complete tested package in a single order line.
With all pumps engaged at full frequency, total discharge capacity reaches 2400 L/min. Across vertical multi-storey plumbing risers, the package comfortably develops up to 21.5 metres of head. Multi-Master autonomous inverter technology enables each pump to take lead control dynamically, providing complete hardware redundancy without requiring a separate central control cabinet.
The compact skid arrangement is supported by an industrial-grade base frame. The set is fully pre-plumbed with two 150 mm manifold connections, dedicated isolation valves, and integrated non-return valves on each discharge line. It connects to a 3 x 380-415 V supply at 50 / 60 Hz with combined rated current of 16.9 A (3 x 5.6 A per pump). A 24L diaphragm pressure tank absorbs initial draw-offs and line hammer, while IP55 enclosure protection and a 16 bar pressure rating ensure long-term mechanical reliability. Liquid-temperature suitability is 5°C to 60°C for all standard clean water booster duties.
Exceptional for high-volume automotive service centres, truck stops, and multi-bay wash pads. Integrating variable speed electronic control eliminates water hammer, extends mechanical life, and lowers lifecycle energy consumption compared to fixed-speed boosting systems.
