One of the ports within the Ports of Stockholm was outfitted with a Flygt pump station for the handling of sewage and grey water. To handle the large amount of waste water without clogging, a Flygt TOP pump station including N-pumps was installed.

England’s Northumbrian Water Ltd (NWL) serves roughly 2.5 million people with water and sewerage services. To better assess its predicted results they conducted a project to measure how much the installation of N-pumps had reduced their costs.

Stockholm’s largest pump station is situated some meters below a site which was once a 17th century palace in the middle of the city. The large flows and central location demanded reliable pumps.
