Dams and Water Reservoirs

Dams are always critical projects. The hydromechanics of a dam must function always and at all times over many years. Failure of the hydromechanics may lead to large-scale catastrophes.

 

As the hydromechanics is always operated in the direct vicinity of drinking water, here too the highest demands are made on the safety of the sealing systems.
Only perfection in the design and manufacture can guarantee the long-term functioning of the dams.
Servomotors (function-optimised hydraulic cylinders) and the highest quality units secure this requirement.

In addition in many dams water turbines are also used for power generation. These complex and highly efficient constructions function by the use of delicately controlling servomotors. These too are designed, built and supplied by Ruhfus specifically tailored for the customer.

 

In order to be able to supply in these area, it needs great trust from customers and installation operators. Ruhfus has earned this trust over many years.
