It addresses common pain points like harmonic distortion, energy waste, and costly equipment damage in pumps. UL-listed for reliability, with IP21 as standard and IP55 options plus flange mounting for flexible installation. This combination supports energy efficiency and asset protection for water utilities and industrial pumping systems. Designed to simplify commissioning, it includes intuitive Hand-Off-Auto control, Drive Composer PC tool, and optional Bluetooth for remote configuration. With energy efficiency at the core, the drive helps reduce energy use, lifecycle costs, and harmonic-related penalties in water treatment and pumping operations.
Product Information
Extended Description
3AXD50000332076 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 performance with an integrated low harmonic filter reduces THDi to below 3% and eliminates the need for external filters or multi-pulse transformers. This improves power quality, lowers grid penalties, and extends motor life. In water and wastewater pumping, expect steadier flow, fewer nuisance trips, and lower maintenance costs. Built-in pump features include sensorless flow calculation, multipump control, level control, soft pipe fill, dry run protection, and quick ramps. These enable precise pump sequencing, reduced water hammer, and longer equipment life in municipal and industrial pumping stations requiring reliable, programmable sequences and safe start/stop behavior. Integrated active supply unit and built-in low harmonic line filter remove the need for external filters or special transformers. Benefit: simpler installation, reduced footprint, fewer cables, and faster commissioning. Application: retrofit projects or new builds with space constraints in pump rooms. Power factor correction and output voltage boost improve motor efficiency and grid interaction. Impact: energy savings, improved process control, and lower operational costs. Application: variable-speed pumping where energy efficiency is a priority. Control and usability are enhanced by Hand-Off-Auto, Drive Composer PC tool, and optional Bluetooth. Impact: easier commissioning, remote diagnostics, and faster optimization. Application: field service, control rooms, and utilities where uptime and rapid tuning matter. Rugged enclosure options (IP21 standard, IP55 option) support flexible installation in indoor pump rooms or protected locations.

FAQs
The drive plugs into the LV bus of existing pump setups, offering a 90 kW (Pn) rated input with 169 A at 400 V, and it supports 480 V for UL configurations. Its integrated low-harmonic filter and built-in supply unit simplify wiring, reducing install time and enabling quick retrofits or new builds without separate external filters or transformers.
Expect THDi to be well below 3%, which minimizes grid disturbances and penalties. The drive also provides advanced pump features like sensorless flow calculation and dry run protection, delivering steadier flow, reduced water hammer, and longer pump motor life in water and wastewater applications.
The standard enclosure is IP21, suitable for indoor installations, with IP55 and flange-mounting options available for harsher environments or alternative mounting configurations. This flexibility helps optimize space in pump rooms and utility installations while maintaining protection levels.
UL listing provides a recognized safety certification, and the unit’s IP-rated enclosures plus integrated filtration reduce external components. Built-in features like soft ramps, level control, and dry run protection lower maintenance needs and downtime, while easier commissioning reduces field service time and improves reliability in municipal and industrial pumping scenarios.
ROI comes from energy savings due to better power factor and reduced harmonics, lower maintenance costs due to protective features, and faster commissioning thanks to integrated tooling. The elimination of external filters and transformers also lowers installation and lifecycle costs, delivering a compelling total cost of ownership improvement for utilities and process industries.
