Product Overview
Stabilising mains supply pressure across expanding commercial tenancies is achieved with the Grundfos Hydro Multi-E 3 x CRNE45-2-2 Three Phase 3 x 7.5kW Variable Speed Booster Pump Set with 24L Tank. Three Grundfos CRNE45-2-2 multistage pumps work in unison to eliminate pressure fluctuations during heavy usage. Part number 93368426 provides the complete tested package in a single order line.
Hydraulic testing demonstrates this booster arrangement provides peak discharge up to 3500 L/min. Across vertical multi-storey plumbing risers, the package comfortably develops up to 59.8 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 package features an industrial-grade mounting skid designed for easy rigging. The set is fully pre-plumbed with two 200 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 77.4 A (3 x 25.8 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.
Tailored for private healthcare clinics, dental centres, and specialist outpatient suites. Integrating variable speed electronic control eliminates water hammer, extends mechanical life, and lowers lifecycle energy consumption compared to fixed-speed boosting systems.
