Product Overview
Balancing high-volume simultaneous fixture draw across major sports venues is the primary role of the Grundfos Hydro Multi-E 3 x CRNE45-4-2 Three Phase 3 x 22kW Variable Speed 304ss Booster Pump Set with 24L Tank. Three Grundfos CRNE45-4-2 multistage pumps work in unison to eliminate pressure fluctuations during heavy usage. Part number 93368432 provides the complete tested package in a single order line.
Engineered for zero-cavitation performance, overall pump discharge scales up to 3500 L/min. Across vertical multi-storey plumbing risers, the package comfortably develops up to 133.1 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 robust mechanical package rests on a vibration-damped structural steel base. 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 132 A (3 x 44 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.
Engineered for winery operations, cellar door tasting rooms, and barrel wash areas. Integrating variable speed electronic control eliminates water hammer, extends mechanical life, and lowers lifecycle energy consumption compared to fixed-speed boosting systems.
