As you surely know, over time pump impellers used in
wastewater applications can become clogged or ragged, thus lowering the pump’s
efficiency. In some cases, clogging can cause the pump to jam completely,
resulting in operational headaches and higher maintenance costs.
Unnecessary and difficult visits by maintenance people to
clean wastewater pumps can be avoided by using the built-in automatic pump
cleaning function in the water dedicated ACQ580 drive. Pump cleaning automatically
starts a series of rapid reverse* and forward rotations to shake debris off the
impeller. The impeller is thereby cleaned, allowing the pump to run more
efficiently, and also extending its lifetime. As a result, risk for downtime
and needless cleaning costs is lowered. In addition, the drive brings lower
costs thanks to higher average pump efficiency.
* Reverse running only where the pump type allows.
