ENCE GmbH offers a special program of attachments, devices and tools for all water-jet pump systems WOMA that includes the following components:

• Manual nozzles with extension lance for cleaning calcination kilns
• High-pressure jets for cleaning, protective layer removal and selective material removal
• Self-propelled and actuated rotary nozzles for surface preparation
• Cleaning heads for vessels, containers, mixers etc.
• Positioners and spooling systems for cleaning heads and rotary nozzles
• Heads and nozzles for pipe cleaning
• Abrasive water-jet super-high pressure cutting systems for demounting of structures and equipment
• Mobile systems for cleaning IBC containers
• Module systems for waste water treatment

The pump systems have the following features:

• Protective frame for safe helicopter transportation
• Air-operated start, using either external compressed air of control panel
• Ex- and fire protection class acc. to EEXIIeT3
• Grounding of electrical parts
• Exhaust gas cooling system
• Gas detector
• Air-operated pump control system, including electric control

For simultaneous operation of several super-high pressure nozzles WOMA Twin Jet system based on two directly coupled pumps has been developed.

• A wide range of nozzles for various applications using only one system - cleaning, rust removal, cutting etc.
• Small nozzle sizes for operation in hard-to-reach places.
• Geometrically accurate nozzle movement, including straightforward, which makes adjustment to the weld profile possible.
• Considerable increase in the amount of waste. Compared with dry sand blasting, the amount of waste is decreased by 98%.
• Dust-free operation to perform other jobs, i.e. coating, simultaneously. Treatment of selective zones is also possible.
• Selective multi-layer coating removal is possible
• Very gentle operation of water-jet systems. Sensitive spots, like welds and connections, will not be damaged.
• Applicable standards allow accurate quality assessment of surface cleaning using water-jet systems
• Low salt content of the surface, because high-pressure water cleans the smallest pockets. On the contrary, sand blasting leads to pockets plugging and conservation of salts in them.
• Water-jet treated surfaces ensure good adhesion and can be used underwater.
• A wide range of abrasive nozzles enables to cut almost all structural materials. Thus, no internal stress, dust or slag occur.
