The museum shows in detail the centuries-old struggle against water. Various models of windmills that were used to pump water are shown in the exhibition. In addition, many machines and equipment related to hydraulic engineering , a large landscape diorama and drawings.
The original steam-driven pump is still preserved and it can also be put into operation. However, it has been powered hydraulically since 2002. In the center of the round machine house is the huge steam cylinder, with a diameter of 3.66 meters, the largest ever built. It drives eight lever arms, each weighing 10 tons, which reach out through the windows. Eight pumps are attached to this in the ring channel, each of which delivers 8,000 liters of water with one stroke. With an output of five strokes per minute, 320 m³ of water per minute were pumped out of the Haarlemmermeer .
The pumping station is part of the European Route of Industrial Heritage .
