More than 150 Pelton runners in patented EFG design …
EFG Turbinenbau can draw on more than thirty years of experience in the production of patented Pelton runners in drop-forged interlocking structure design. Drop-forged single buckets provide for maximum quality and meet even the highest safety standards significantly better than buckets in conventional designs. This runner technology is complemented by state-of-the-art CAD-CAM technology in the production process allowing for shorter delivery periods when compared to runners in monobloc design, in particular for spare runners. As the runner is made of single buckets, coating technologies can be applied that ensure longer service life also in cases of increased abrasion, and we are also able to respond more quickly in the event of failures or breakdowns and to reduce the overall cost of repair works.
Francis turbines are the most widely used type of turbines in the world and have been operating on the same basic principle for over 160 years. Of course, many details have changed, which is why modern Francis turbines can achieve hydraulic efficiencies of more than 94%.
The Francis replacement runners provided by EFG are welded constructions made from forged solid raw material to meet highest quality standards. These include the non-porous nature of the surfaces or the dimensional accuracy, to name just a few examples. Another advantage is the practically absolute freedom in the selection of the profiling and the twisting of the blades in the design process.
In the case of high machine capacities and correspondingly complex and extensive refurbishment works, we regularly refer to long-standing and successful partnerships.
Major overhauls, repair and automation of existing plants, no matter who the manufacturer was or how old these plants are. Due to our many years of experience, we are familiar with all technical aspects of hydropower technology.
At the start of a project we discuss possible variants of the technically and economically optimal use of the existing plant with the power plant operator. This impartial consultation then serves as clear basis for decisions on necessary measures.
Shut-off devices are an integral component of almost every hydropower plant. These are positioned either directly upstream of the machine set as turbine shut-off devices or in the water inlet area, mainly in medium and high-pressure systems, as security devices in the event of a pipe burst.
The high standards with regard to the reliability of the functioning in normal operation as well as in cases of emergency make continuous maintenance and servicing necessary. For this reason, EFG has specialised in the manufacturing, the refurbishment and the repair of shut-off valves of various makes and types.
As a one-stop shop EFG offers everything from a single source – starting from the design up to the finished coated parts, the various production steps take place in our own company. Decades of experience and the wide range of manufacturing techniques enable us to manufacture components according to your technical specifications with the highest degree of quality.
Our component production of various individual parts for machine engineering, special machine engineering as well as steel hydraulic structures includes development, production, assembly, QA, and delivery.
All-round support from the first consultation to commissioning.
