Clogged or blocked pumps in sewage networks are causing huge problems globally. The cost can be over a hundred million USD for the industry in a single country.
Every time a pump is blocked, costs like cranage and technician time are incurred, combined with the fact that the cleaning task is dirty and necessitates special attention to health and safety due to risks such as gases, debris, and hypodermics needles, etc.
These high maintenance costs can, in many cases, be reduced with the pump cleaning function that you can find in the PSTX soft starter from ABB. The pump cleaning function performs several cleaning cycles triggered at every start or when it detects a blocked pump through torque monitoring or through time set points.
The pump cleaning function is a standard feature in the PSTX soft starters. It is a sequence of cleaning cycles in a series of slow reverse and fast forward rotations of the impeller. The intelligent pump control menu has an easy-to-use wizard feature that will help to set up the function for different pump applications.
