Product Overview
Commercial craft breweries and beverage bottling plants specify the sanitary Grundfos Hydro Multi-E 3 x CRNE32-4-2 Three Phase 3 x 7.5kW Variable Speed Booster Pump Set with 24L Tank. Three Grundfos CRNE32-4-2 multistage pumps work in unison to eliminate pressure fluctuations during heavy usage. Part number 93368412 provides the complete tested package in a single order line.
Across wide-ranging facility flow profiles, delivery volume reliably peaks at 2400 L/min. Across vertical multi-storey plumbing risers, the package comfortably develops up to 101.9 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.
Built to withstand industrial plant room demands, the unit features a rugged steel skid. 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 58.7 A (3 x 19.6 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.
Widely used in commercial nursery glasshouses, wholesale market gardens, and turf farms. Integrating variable speed electronic control eliminates water hammer, extends mechanical life, and lowers lifecycle energy consumption compared to fixed-speed boosting systems.
