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.

The wind turbines needed are built in various ways.
The most complex and at the same time most reliable way is the adjustment of the rotor blades with the aid of hydraulic cylinders (pitch cylinders).

This is also something that Ruhfus is involved in.

Energy provision at any time, in any situation and in high density is a requirement of our industries.

So-called piston gas accumulators are used in high performance presses, high voltage emergency stop switches, pressure moulding and injection moulding machines,... even in roller coasters.
The tubes for these come from Ruhfus, in large quantities, in excellent inside surface qualities and always order-specific in length and diameter. Just as the customer needs them.
Forward-looking stockpiling, sophisticated production logistics, consistently high production quality, secure batch retraceability and routine in processing are here key criteria that our customers have appreciated for many decades.
