Product Overview
Shopping centres and large retail plaza amenity cores maintain balanced line pressure using the Grundfos Hydro Multi-E 3 x CRNE 20-1 Three Phase 3 x 2.2kW Variable Speed 304ss Booster Pump Set with 24L Tank. Three Grundfos CRNE 20-1 multistage pumps work in unison to eliminate pressure fluctuations during heavy usage. Part number 99752351 provides the complete tested package in a single order line.
The precision-balanced hydraulic package effortlessly generates system flows up to 1750 L/min. Across vertical multi-storey plumbing risers, the package comfortably develops up to 20 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.
Designed for minimal footprint in compact plant rooms, the system features a rigid base. The set is fully pre-plumbed with two 100 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 13.3 A (3 x 4.4 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 commercial laundries, uniform cleaning plants, and linen processing facilities. Integrating variable speed electronic control eliminates water hammer, extends mechanical life, and lowers lifecycle energy consumption compared to fixed-speed boosting systems.
