How to prevent pump and pipe clogging with ABB pump cleaning routine

In applications where the pumped liquid contains small particles capable of jamming the pump, there is a need to have a cleaning procedure, otherwise there is a risk of the pump becoming fouled and even breaking.


The challenge

Blockages in foul pumps and pipes are caused largely by rags sticking to the impeller. As well as downtime, clogging can lead to sewage pollution. A total system failure can lead to effluent leakage, with implications for the environment and health and safety, as well as incurring clean-up costs and resulting in possible breaches of legislation.

The solution

Pump cleaning  software is suitable for sewage treatment processes and is used to prevent pump and pipe clogging. The function can be timed to occur without interrupting the pumping duty cycle, helping to maximise process uptime.

How it works

The  pump cleaning  software performs a number of cleaning cycles every time the pump starts. Each cycle consist of a series of rapid ramp ups in both forward and reverse directions. Taking one to two minutes to complete, the cleaning cycle removes the debris from around the pump volute, preventing it from entering the pump and blocking it when the pump ramps up from zero to its normal operating speed.

Key Benefits

- Reduced tanker mileage
- Reduced plant downtime
- Reduced maintenance needs and costs

How do I get the pump cleaning function?

The pump cleaning function is a feature of the ABB industrial drive modules for water and wastewater applications. The drives’ pump specific features ensure accurate control of water flow throughout the processing cycle – from raw water, through utilisation, to wastewater treatment.

The modules include pre-programmed pump control functions. These functions are easy to select and implement using pre-configured macros for single and multi-pump applications. In addition, an easy-to-use programming utility is provided, enabling users to further customise their drives.

ABB industrial drive modules are the ideal choice for water and wastewater applications. Specially designed to meet the demanding needs of squared torque pump control, these highly advanced drives maximise uptime and minimise energy costs in pumping systems.

The modules are designed for cabinet assembly and are easily mounted side-by-side. Intelligent start-up assistant ensures that drive commissioning is straightforward and the functions needed for most pumping systems can be easily implemented with the pre-programmed macros. Starting up a pumping system and optimising its performance is extremely easy. ABB industrial drive modules include everything needed for reliable and efficient pump control in water and wastewater applications.
