In co-operation with ABB, we’ve developed a range of VFDs which, with their unique Flygt software, are specifically tailored for wastewater pumps. Using a standard VFD usually means a derating of your pumps. But with the ACS550, you can expect all the advantages of speed regulation, plus top pumping efficiency.

Fewer call-outs
To reduce the risk of clogging a special program has been developed to help keep impellers clean. When the ACS550 senses an increase in load that exceeds a preset value, it triggers a cleaning sequence. Not only does this improve reliability, but it also means fewer emergency call-outs.

Pre-programmed for wastewater pumping
As pump experts, we know exactly what you need. The ACS550 is supplied with a selection of pre-settings, reducing the number of parameters you need to handle by more than 90 percent. The ACS550 can communicate with other pump controllers such as Flygt’s
FMC and can interface with different SCADA systems, including AquaView.
