Traditional and innovative

Family-owned for seven generations

Our company history started in 1861, and is also a history of the family to this day because of values such as awareness of tradition, ability to adapt and innovative spirit. 

In many cases, we have been the first manufacturer on the market to find and deliver a technical solution for changing situations. We have therefore always succeeded in adapting our range of products to market changes that have been drastic at times, and marketed them worldwide. Our current company departments Pumps, Cable winches, Pool technology, Casting and steel components, Steel hydraulic engineering and valves have arisen from these technical developments. 

Our in-house foundry has always been the focal point and the heart of the company. 

It is our unique selling point as far as the competition is concerned, and makes the unique manufacturing depth of our production possible.
