Case Study

Retrofit Of A Brand New Pump Station


Like many pump stations, the Kellogg Pump Station was experiencing issues with impeller clogging events. Unlike many problematic pump stations, the Kellogg pump station was a newly constructed pump station. The new pump station had been equipped with non-Flygt, conventional extended shaft, solids-handling pumps. These pumps quickly proved that they were unable to handle today’s “modern trash”, which is laden with non-disposables, FOG and “items that should not be flushed.” Due to clogging problems, the pump station was experiencing reduced pump performance, longer pump run times, significant vibration issues and the need to be physically unclogged.

The utility did not want to purchase new pumps to “see if they would work.” They wanted proof. Xylem, Inc. offered the Flygt N-Pump “Try and Buy” program. This program provides an appropriately sized Flygt-brand electric submersible N-Pump unit for an agreed-to trial period to the utility for installation, to replace an ailing pump. After the pre-agreed time period, when the Flygt N-Pump performs satisfactorily, the utility agrees to purchase the pump.
