Product Information
Extended Description
3AXD50000751839 ABB: The ACQ531-01 drives deliver innovative pump features for the water and wastewater industry, securing energy efficient flow of water and wastewater in your pumping solutions. This robust and compact wall-mounted drive has built-in simple pump application functionality. Usability is further enhanced with the optional intuitive Hand-Off-Auto control panel, the PC tool Drive composer and an optional Bluetooth=C2=AE control panel. The built-in energy calculator visualizes the energy savings achieved with the use of the drive. The ACQ531-01 variant comes in an IP20 enclosure as standard and can be installed on the wall.
Built-in pump application features optimize start/stop sequencing and speed control, reducing energy use and motor wear across municipal and industrial pumping networks. The business impact is lower operating costs and longer equipment life, translating to reduced downtime in critical water facilities and wastewater lift stations. In practice, engineers can configure pump curves, torque limits, and soft-start profiles quickly, ensuring reliable delivery under highly variable demand. IP20 enclosure and compact wall-mount design simplify installation in standard control panels, enabling quick deployment in tight spaces like confined plant rooms and skid-mounted packages. This reduces wiring complexity and cabinet footprint, speeds commissioning, and lowers installation labor across retrofit projects and new-build facilities. Field technicians appreciate robust protection with easy access for inspection, routine maintenance, and future upgrades. An integrated energy calculator visualizes potential savings under real operating conditions, supporting data-driven energy-management programs and budgetary approvals. It helps quantify ROI for upgrades, making finance reviews clearer and procurement faster. Operators gain visibility into how drive settings affect flow, pressure, and overall system efficiency, enabling proactive maintenance decisions. Optional Hand-Off-Auto control panel provides straightforward operator switching, while the Drive Composer PC tool speeds configuration, commissioning, and diagnostics across multiple sites. These tools reduce field service time, lower maintenance costs, and shorten mean time to repair by enabling remote diagnostics and guided workflows. Together they enable faster recovery after interruptions and more predictable pump performance, even in remote or hazardous environments. Compatibility with ABB ecosystem tools and standard motor-control interfaces ensures seamless integration with existing drives, sensors, SCADA, and remote monitoring systems. The solution scales from small municipal facilities to large pumping networks while preserving performance, reliability, and serviceability across fleets. Designed for water treatment, industrial pumping, and process industries, it supports compliant, maintainable, and upgrade-ready infrastructure.
