About us


We are people with a great passion for propeller and mechanical engineering, the maritime industry and for our customers. Excellent service, advice with know-how and the pursuit of delivering only the highest quality are not only the pillars of our company, they are part of our personality.

Sales and propeller dimensioning

A good propeller is only as good as its dimensioning! Propeller technology in particular, which is regarded as the supreme discipline in shipbuilding, requires a great deal of experience. Our employees in sales and on site at boat shows worldwide have a very sound knowledge of propeller technology, which requires good training and is put into practice through their own experience as water sports enthusiasts.

In addition to our in-house developments, the high-quality VARIPROP and VARIFOLD rotary and folding propellers for sailing boats, we also manufacture fixed and high-performance propellers for motor yachts.

Propellers and products for all situations

With our extensive experience, we also manufacture special propellers for free-fall lifeboats used worldwide, as well as agitator propellers for medical and cosmetic products, for example.

We also manufacture ship shafts, stern tubes, modern stuffing boxes, couplings and rope cutters for you and many other products such as shaft bearings, shaft brakes and mechanical seals are available from us.

Take a look through our extensive online shop or contact us if you have any questions. Our sales team will be happy to advise you to the best of their knowledge and belief and always with a twinkle in their eye.
