At Hammelmann, innovative spirit and know-how meet around 75 years of experience as a market leader in the development of powerful high-pressure pumps and technical systems for high-pressure applications up to 4,500 bar.
Our expertise for the marine industry: high-quality water jetting systems and a comprehensive range of accessories for effective corrosion protection as well as injection pumps for alternative fuels.
Reduce expensive hazardous waste by 95% when cleaning and stripping paint from ships. Sandblasting is a thing of the past - with our water jetting technology, you can work cleanly, effectively and in a way that conserves resources. The remote-controlled, semi-automatic SPIDERJET, DOCKBOY and DOCKMATE systems, which are designed for one-man operation, reach even hard-to-reach areas, suck up water and dirt directly and collect residues for easy disposal. Surfaces are ideally prepared for subsequent coating. Our systems also clean parts like turbine blades, propellers, superstructures or ballast tanks.
Comprehensive service and individual advice, fast availability of spare parts and uncomplicated accessibility 24/7 – that is the ambition of around 500 employees at the company headquarters in Oelde, Germany, as well as at subsidiaries in the USA, Australia, Spain, China, France, Türkiye and Switzerland. Additionally 40 international representatives ensure presence worldwide.
