Pumping station Leemans at Den Oever is one of two pumping stations that are built for the reclamation of the Wieringermeer. In 1994 the pumping station was renovated and a hydraulic installation was delivered under the HYCOM flag.
The pumping station can be closed and opened through hydraulic cylinders. In 2017 HYDAC started the revision of the existing hydraulic part. Both the cylinders as well as the aggregates are being fully overhauled and where necessary, the hydraulics will be adapted to the existing NB6000 conditions.
