Description
The ACQ580-31 offers full water functionality with a clean supply (THDi less than 3%), easily meets harmonic standards, and simplifies system design by eliminating the need for overdimensioned components. Its straightforward installation with no external hardware improves system efficiency and reduces overall costs. ACQ580-31 offers you full water functionality and clean supply with THDi less than 3%.

The ABB ACQ580 is a drive built for water and wastewater pumping. It has the ACS580 hardware platform with pump-specific software, so features that usually need a PLC are built in.
Pump functions built in
- Multipump control: run up to several pumps in parallel with alternation and cascading to share wear.
- Level control for tanks, wet wells and lift stations.
- Soft pipe fill to avoid water hammer when starting into an empty pipe.
- Dry-run and pump protection to stop the pump on loss of suction or abnormal load.
- Pump cleaning (forward/reverse sequences) to clear ragging in sewage pumps.
- Flow calculation without a separate flowmeter, and energy savings counters.
- PID control with sleep and boost for pressure boosting.
For installations with strict harmonic limits or generator supply, the ACQ580-31 ultra-low harmonic version offers THDi below about 3% without external filters.
Sizing
Use the pump motor nameplate current and normal-duty rating for centrifugal pumps. Positive displacement and progressive cavity pumps are constant torque — size them on the heavy-duty rating.
Typical applications
- Water supply and booster pumping stations
- Sewage lift stations and wet wells
- Water and sewage treatment plants (STP/ETP/WTP)
- Irrigation pumping
- Borewell and submersible pumps
Selection tips
- Use normal-duty rating for centrifugal pumps, heavy-duty for PD pumps.
- Choose ACQ580-31 when harmonic limits or DG supply apply.
- Use built-in multipump instead of a PLC for simple duty/standby sets.
- Check cable length to submersible pumps; long cables may need output filters.
ACQ580_Water & Waste Water Drives: frequently asked questions
What is the difference between ACQ580 and ACS580?
They share hardware, but the ACQ580 has water-specific software: multipump, level control, pipe fill, dry-run protection and pump cleaning.
Can one ACQ580 control several pumps?
Yes. Multipump functions coordinate several pumps with alternation, so a duty/assist/standby set can run without a separate PLC.
Can the ACQ580 run submersible pumps?
Yes. Check motor cable length and the pump's minimum speed requirement; we can advise on output filters and settings.
