More transparency – with KSB Guard

Even high-quality pumps can sometimes experience malfunctions whose exact cause can only be determined by a long-term diagnosis. External factors are often to blame, and these can only be identified if the affected pump is monitored over a longer period of time using suitable sensor technology.

Even high-quality pumps can sometimes experience malfunctions whose exact cause can only be determined by a long-term diagnosis. External factors are often to blame, and these can only be identified if the affected pump is monitored over a longer period of time using suitable sensor technology.

The project:

Establishing the cause of pump failure

Four Sewatec D pumps installed in the return sludge pumping station of the Altenstadt waste water treatment plant had been experiencing failures at regular intervals. After commissioning, KSB Guard found that the vibration limit specified had been exceeded frequently. The maximum value measured for all four pumps was over 18 mm/s – well above the limit of 5 mm/s.

The client:

Abwasserverband Altenstadt

The municipality of Altenstadt is located in the Wetteraukreis region of Hessen, Germany, and comprises eight districts. The waste water treatment plant of Abwasserverband Altenstadt (Altenstadt waste water association) ensures urban drainage and trouble-free waste water disposal for the municipality’s 12,000 inhabitants. The waste water treatment plant has been designed for up to 25,000 inhabitants.

The challenge:

Determining external factors

Biological treatment is an important step in the waste water treatment process which involves dissolved organic substances and nitrogen compounds being decomposed by microorganisms. The activated sludge from the final clarifier is then returned to the aeration tank. Following the recurrent failures, KSB Guard was installed and commissioned to enable data on the condition of the return sludge pumping station to be viewed at any time.

The solution:

Failure diagnosis via long-term measurement

Thanks to KSB Guard it was possible to find the cause for the recurring vibrations: the discharge pipe had been directly mounted to the pumps instead of being suspended from the ceiling. As a result, the pumps had to bear the discharge pipe’s load which meant that remedial action was required. Two months after putting KSB Guard into operation, the piping installation was modified. Modification work involved attaching a load-bearing steel structure to the ceiling and fitting flexible rubber inserts between the piping and the pumps.

After returning the pumps to service, the vibration values dropped below 1 mm/s after only a short time – a result the customer was more than satisfied with. Until this point the Altenstadt waste water association had been testing KSB Guard free of charge, but now came the decision to purchase KSB Guard and install it permanently in the plant as a monitoring solution.

KSB Guard’s straightforward installation proved to be a particularly convincing feature. In addition, all registered users have round-the-clock access to the pumps’ data via the KSB Guard web portal and are immediately notified by e-mail in the event of any irregularities, allowing major damage and breakdowns to be reliably avoided.
