Customer satisfaction through quality

Since the foundation in 1957 were sold between 70,000 and 80,000 agitators. With our Head office in Sulzberg we operate internationally with an export share of 65%. Our plants can be found in 52 different countries. Despite the large internationality, we stand for quality and know-how.
The entire value-added chain is almost exclusively on site in Sulzberg Germany.


With our products we guarantee a long service life and easy and quick maintenance.
This makes it possible to replace parts even after 10 years thanks to the modular design.

Solutions for each customer's requirements

Our mixers are suitable for biogas, agricultural or industrial plants and can be operated electrically or in the agricultural sector by tractor.
With our products we ensure that the milieu conditions are optimally positioned to achieve the highest possible output in your biogas tank.
With a temperature of between 37 and 42°C the best growth of methane bacteria takes place.
Through our long-axis agitators and submersible motors the optimal temperature distribution in the tank is reached. This leads to a higher biogas yield and guarantees high process stability.
In addition, the fermentation and the distribution of nutrients and vitamins to the supply of micro-organisms are ensured by agitating with the SUMA agitators.
You can use our products at pH-values between 5.5% and 8.5% within the fermenter.
60 employees and 10 apprentices are working on your desired requests to implement and generate solutions for a wide variety of challenges for nearly 60 years.

Complete „made in Sulzberg"

The engineering department develops and designs all agitators in house and uses the own test basin to receive further information about the behavior of the. Thereby the propeller geometry can be optimized continually.
The flow simulations can also be used to dimensioning your future plant to establish the most ideal use of the agitators.
Furthermore, the engineering department supplies data sheets including installation information on request, with the aid of this data it is possible to get important information about the products in advance.
Since customer's benefit and customer satisfaction have highest priority for us, we offer also step-by-step installation and repair instructions with on-site installation images and 3D views, clearly spare parts lists and operating instructions.
As a result of the high demand our tutorials are available in German as well as in English for our international customers.

Internationality and years of experience

From our pioneering role as the inventor and first developer of electric mixers, SUMA became a global, innovative and quality conscious company, which by the independent companies Brasuma in Brazil and Suma America Inc. in America is not only at home in Allgäu (Bavaria, Germany).
In keeping with our motto "it´s our invention" we would like to make stirring and mixing as simple as possible for you.
