By combining built-in pump control features with efficiency-enhancing functions, it delivers lower operating costs while simplifying maintenance and integration with plant PLCs.
Product Information
Extended Description
3AXD50000359325 ABB: The ACQ580-31 drives deliver innovative pump features for the water and wastewater industry, securing energy efficient flow of water and wastewater in your pumping solutions. The ultra-low harmonic variant provides ultimate harmonic performance, reaching even less than 3 % THDi, and exceeding the requirements set by low harmonic standards and recommendations. The drive includes an active supply unit and integrated low harmonic line filter, meaning there is no need for external filters, multi-pulse arrangements or special transformers.
Other features include output voltage boost and power factor correction. This robust and compact wall-mounted drive has built-in pump application functionality such as sensorless flow calculation, multipump control, level control, soft pipe fill, dry run protection, quick ramps and a solution for keeping the impeller of the pump clean. Usability is further enhanced with the intuitive Hand-Off-Auto control panel, the PC tool Drive composer and an optional Bluetooth=C2=AE control panel. The ultra-low harmonic wall-mounted variant comes in IP21 enclosure as standard. Also, IP55 and flange mounting units are available.
Ultra-low harmonic architecture combines an integrated low harmonic line filter and an active supply unit, delivering THDi below 3% without external filters or multi-pulse transformers. That translates into lower installation costs, easier compliance with low-harmonic standards, and improved compatibility with existing electrical infrastructure in water and wastewater plants. Output voltage boost and power factor correction enhance pump efficiency under fluctuating loads, providing improved motor efficiency, reduced upstream currents, and smaller contributors to energy bills for large pumps. Built-in sensorless flow calculation, multipump control, and level control provide advanced process automation right from the drive, reducing commissioning time, minimizing software integration effort, and helping prevent dry-run events and overfills in pumping processes. Soft pipe fill, dry run protection, quick ramps, and automatic impeller cleaning extend pump life and lower maintenance costs. Hand-Off-Auto control panel, Drive Composer PC tool, and optional Bluetooth control panel simplify technician training and remote diagnostics. Standard IP21 enclosure ensures safe indoor mounting with compact wall-mount form factor; IP55 and flange-mount variants offer rugged outdoor and space-constrained installations, while seamless integration with common automation platforms reduces wiring complexity and installation risk.

FAQs
The 3AXD50000359325 integrates with standard LV AC infrastructure (400 V, 32 A) and features an internal low harmonic filter, reducing the need for external components. Its compact wall-mount form and IP21 enclosure simplify retrofits in existing pumping stations, while IP55 variants provide options for tougher environments.
THDi below 3% is achieved through the drive's integrated low harmonic filter and active supply unit, eliminating the need for external multi-pulse arrangements or transformers. Lower harmonic distortion improves power quality, reduces transformer and cable heating, and extends motor life in critical water/wastewater pumping applications.
Yes. The drive includes multipump control and level control features that support coordinated operation across multiple pumps, enabling sequencing, level-based start/stop logic, and reduced surge risks. This helps optimize pump fleet efficiency and reliability in treatment facilities.
The drive is UL-listed for safety and performance, with standard IP21 enclosure and optional IP55 variants for harsher environments. It is designed to meet low-harmonic standards and reliability requirements typical in water and wastewater applications, supporting compliant operation in many regional guidelines.
Benefits include reduced installation time due to built-in filters, lower energy costs from voltage boost and power factor improvements, and fewer external components. Built-in protections such as dry-run and impeller cleaning reduce downtime, while sensorless flow control and diagnostics simplify maintenance planning and extend pump life.
