Product Overview
Multi-deck commercial car parks and automated fleet wash facilities install the Grundfos Hydro Multi-E 3 x CRNE45-1-1 Three Phase 3 x 4kW Variable Speed 304ss Booster Pump Set with 24L Tank. Three Grundfos CRNE45-1-1 multistage pumps work in unison to eliminate pressure fluctuations during heavy usage. Part number 93368420 provides the complete tested package in a single order line.
Operating seamlessly under modulating inverter control, the set yields flow up to 3500 L/min. Across vertical multi-storey plumbing risers, the package comfortably develops up to 31 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 skid incorporates a low-vibration structural steel foundation. 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 40.9 A (3 x 13.6 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.
Suited to multi-storey car parks, commercial vehicle detailing bays, and fleet depots. Integrating variable speed electronic control eliminates water hammer, extends mechanical life, and lowers lifecycle energy consumption compared to fixed-speed boosting systems.
