Wasserfall der Ems am Hanekenfähr bei Lingen.

Flowserve Pump Division’s Hengelo, Netherlands office, supplied in 2003 six high capacity, concrete volute pumps to the German State of Lower Saxony, Department of Water and Coastal Protection, for a dam that was built in Northern Germany. The pumps, valued at US$ 3 million, are part of a US$ 210 million semi-open flood control dam that is used to boost the water level of the Ems River.

These Flowserve BSV concrete volute pumps (types BSV 225 and BSV 260) have impellers ranging from 2.3 m (89 in) to 2.6 m (102 in) and are capable of discharging 100 m3/s (1.6 million USG/min) at heads up to 4.8 m (16 ft). The pumps have been installed in six pillars along the 305 m (1000 ft) wide dam, connected by 55 m (180 ft) control gates. The pumps will be engaged to increase water depth for large seagoing vessels built 32 km (20 miles) upstream at the Meyer Shipyard. The dam will also function to safeguard the sub-sea level inlands against flooding due to storm surges.

To complete this project, Flowserve engineers had to perform computational fluid dynamics (CFD) calculations and 1:5 scale model testing. The tough site conditions and the limited installation space also presented demanding circumstances for project engineers. The successful completion of this project demonstrates the willingness and ability of Flowserve to work closely with customers to develop sound engineered solutions for their challenging problems.
