Emotron VFD for important water leveling point
The pump station is the most important water inlet of the Krimpenerwaard. Fresh water is brought in from the river Lek to keep the water level in times of drought on the one hand and to flush the water level section and provide it with better quality water on the other.
The fish-friendly pump is run by a permanent magnet electric motor and Emotron AFE variable frequency drive (VFD). The Emotron VFXR 2.1 makes it is possible to capture a running PM motor.
Solution for fish migration
The pump was primarily remodeled to solve a fish migration bottleneck. 1 of the 2 existing pumps was replaced by a pump where the concrete casing was replaced by a pump block of a larger size. The pump has a capacity of 200m3 per minute and drains a large part of the Krimpenerwaard.
After completion, the pump was tested for fish safety for both draining and turbine operation. The pump has proved to be very fish-safe for both draining and turbining.
