High pressure water jet cleaning and cutting

High pressure water jet cleaning is usually done with 500 to 3200 bar of pressure. High pressure pumps produced by URACA company are made for outdoor use, powered by diesel engines so that they are independent of electrical outlets. When used indoors, they mostly rely on electromotors as their power source. High pressure solutions are complete units, with built-in water filtration, independent booster pumps and control and regulation systems for setting and control of parameters. Parameter setting, mainly pressure and flow rate are set according to desired application, e.g. drain cleaning or paint coat removal. Machines are controlled remotely using remote control system, by person using the machine. Machines come with different accessories (cleaning guns, nozzles, rotary heads, jets, injectors, spherical heads etc. Our range of accessories is very broad and also determined by desired application. When using injector with point jet nozzle, you can cut different technical materials even outside of workshop. It can also be used in explosive, combustible or otherwise dangerous environments.

Chemical cleaning

Chemical cleaning of materials is used mainly in cleaning of enclosed systems, e.g. cooling of pumps, turbines, compressors or specific heat exchangers and coolers clogged by waterstone. It´s also used for cleaning of cooling tower lamellas etc. Circulation of chemical solutions in polluted piping circuits removes the impurities without needing to remove individual components. For best results it can be combined with other cleaning methods, e.g. high-pressure water jet.

Ultrasonic cleaning

Ultrasonic cleaning is convenient method of cleaning filters and filter
inserts with very fine filtration, where mechanical cleaning is simply
insufficient or can lead to damaging of the filters. It´s also convenient
when used for cleaning of small components, which can be immersed

into ultrasonic bath. Ultrasound in combination with cleaning solution
can very effectively remove impurities from capillaries or small filter
membranes.

Suction dredger works, cleaning and dredging of drains and sewers

Suction dredger is a high-performance machine with suction power of up to 10000 m3/hour. Its most convenient to use for dredging of transport vessels of dry, paste and liquid materials, including dangerous substances, as it is built according to ADR provisions. Similarly, it can be used as a suction sewage cleaning combined-use vehicle for simultaneous cleaning and dredging of sludge when cleaning sewers, piping systems, shafts, sumps, cesspools, tanks, reactors, silos etc. It´s also used for suction loading and transport to dumps for common materials like sand, gravel, pellets, cement, lime, ash, soda and other technical or food products.

Industrial grade soda and dry ice cleaning

Industrial grade soda and dry ice cleaning is a supplementary alternative cleaning method to water jet cleaning technology, with which industrial grade soda or dry ice are injected into waterjet gun output with injector. This helps to remove impurities from the surface of materials even with smaller working pressure. Use of this method is most convenient in electrotechnical and food industries. Its biggest advantage is safe dissolution of injected substances after the cleaning is finished, meaning that no abrasive particles (e.g. sand when using sand cleaning method) are left in the cleaned equipment.

Wet sandblasting

Cleaning by wet sandblasting is also a supplementary alternative cleaning method to water jet cleaning technology. With this method, the injector is used to inject sand, steel grit, glass beads or other abrasive material into the output of waterjet gun, which raises the kinetic energy of water jet to help remove specific hard crusts, corrosion or other undesirable coating. In comparison to traditional dry sandblasting, this method has an advantage of the process not causing any dust and therefore not threatening the health of operators and not causing any damage to workplace or environment.

CLEANING OF BOATS, TRAIN TANK CARS, TRUCK TANKS AND OTHER MEANS OF TRANSPORT

Cleaning with high pressure water jet is used for cleaning of outer surface of boats from kelp, impurities or damaged paint coats and corrosion when the boats are being repaired in drydocks. It is also used for cleaning of inner surfaces of tanks in tanker used for transportation of diesel, oil, petrol and other substances. They are also similarly used for cleaning of inner surfaces of train tank cars, truck tanks and other tanks, sumps, reactors or other closed containers. For these purposes we use spherical self-rotating heads produced by URACA company, copying the inner surface of sphere, so called TWK – TankWaschKopf. For operating these heads, we also employ various operators from URACA company, so that the whole inner space is cleaned without the presence of other persons in these tanks.

Cleaning of churches, monasteries, chappels and other sacral buildings

Cleaning with high pressure water jet is primarily used for cleaning or removal of damaged paint or plaster coats on various historical sacral buildings. Water jet technology is impact-less and non-dynamic, which means it doesn´t cause additional impact or cracks on cleaned buildings and helps to avoid damaging of unique historical objects.

Cleaning of historical castles, manors and mansions with water jet

According to several international standards is water jet technology most suitable and recommended method of cleaning, blasting or local hydro-demolition of plaster and paint coats or concrete in all historic buildings, high-rise buildings, bridges, chimneys, cooling towers etc. Similarly, it can be used for remediation of concrete structures, as it is one of few impact-less methods, meaning it does not cause dynamic microcracks in cleaned objects, which prevents possible damages.

Cleaning of sewers, drains and pipes

Pumps made by URACA company are used internationally for cleaning of sewers and pipes. They are used for ecological cleaning of pipelines and pipes of diameters between 10 mm and 1000 mm. Cleaning of large-scale piping systems also poses no problem. We manufacture and use a wide range of various handling systems for effective cleaning. Important part of this process is simultaneous sludge dredging, provided by our suction dredgers or suction sewage cleaning vehicle, equipped with URACA pumps with output of up to 250 kW, pressure of 180 bar and flow of up to 420 l/min.

Cleaning of heat exchangers, tube sheets and heat exchanger shells from inside and outside

One of the most wide-spread technologies of heat exchanger cleaning in chemical, food, rubber and paper industries are cleaning with high pressure water jet with pressure of up to 3000 bar or 300 MPa. We use wide selection of our partner company URACA for effective and high-quality cleaning.
