Hydropower as an instrument. The power of water has been used by mankind since ancient times. Hydropower has powered mills and lifted heavy loads. Hydropower is an important regenerative energy source. But water can be much more.

The revolutionary idea of using the mechanical effects of running water to clean with a huge pressure formed the foundation of Woma in 1962. Since then, this idea has become the driving force behind the company.

  • Woma is one of the leading manufacturers of high-pressure pumps, high pressure systems and accessories.
  • Our constant research and development has ensured today's systems can deliver up to 4000 bar - quadruple the pressures found at the deepest point of the ocean.

As part of the Kärcher Group, Woma provides a comprehensive worldwide dealer and service network.

Eco MK3



The new Ecorunner brings pressure quickly to where it is needed. The vehicle and the waterjet combination unites the transport and operation of ultra-high pressure technology in a single device. This modular design allows fast and flexible conversion for all high pressure water jetting applications.

The advantages:

  • The modular high pressure unit is quickly and easily changed using a forklift. This simple "plug and spray" concept allows the vehicle to quickly provide a deployable high pressure unit capable of delivering up to 3000 bar and 235 l / min.
  • The high-pressure unit is driven by the engine of the vehicle via an integral split shaft gear box. This saves space and weight, as additional engine and the fuel tank is no longer necessary.
  • Low noise thanks to the entire housing of the high pressure unit and the engine of the vehicle.
  • An electric 24-volt device with an E-EXI interface is included in the high-pressure unit for use in areas falling under the heading of "explosion".
  • A Class B EU driving license is sufficient for the operation of the vehicle, which has a total weight of about 3.5 tonnes.

Major maintenance Noorderkroon.

Saturday, December 20, 2014 was a special day for Urk Zeekadetkorps. After a long preparation period, the corps ship arrived in the port of Urk. The Northern Crown is a former Norwegian Fjords seaworthy vessel, which was used to supply the various islands off the Norwegian coast. After that the ship years as a training vessel hazards to the Judicial Service of the Dutch government, which also explains the old Austro-color scheme of the ship. Precisely this last function of the vessel makes it ideally suited to serve for the Urk Zeekadetkorps as a platform, through the ample accommodation and facilities on the ship.

Woma Netherlands along with many voluntary capacity have begun on August 21, 2015 with the renovation of the Northern Crown. Thanks to the provided equipment consisting of a Ecomaster MK3 and EcoCold 500/30 Classic ship within the shortest times stripped of its coating. Watch the video.
