The rotating enz nozzle for cleaning surfaces is remarkable for its high efficiency. It outperforms conventional flat jet or round jet nozzles with a large margin. This special nozzle for cleaning surfaces is rotated by the cleaning liquid by means of an impeller. The exhaust axis has an inclination against the central axis of the rotating nozzle, which results in a circular movement.

  • Surface Cleaner: To remove deposits of concrete-slurry, cleaning of store fronts, steps, walls, traffic signboards etc.
  • Turbo Killer: for the cleaning of steps, walls, artificial surfaces, traffic signs, etc.

With this enz tool large channels will be efficiently cleaned. They can be used for dimensions of 24 – 120 inch. The skids are easy to adjust and can even be adapted to clean egg-shaped or oval pipe profiles. The propeller nozzles have been designed for the use of recycling-water, of course they can be used for fresh water as well.

  • For cleaning large channels

The enz rotating nozzle is provided with an eccentrically supported rotor, which produces very fast vibrations and pulsating jets. The resulting pulsations become as strong that deposits up to 4 inch thickness are disintegrated. Thanks to the application of the rotopuls nozzle, the more expensive work with the cutting tools or with the chain flail head can be avoided in many cases. Important: Rotopuls nozzles develop strong hydraulic impacts and vibrations. This can possibly cause damage in some sort of pipes (e.g. earthenware pipes, thin-walled plastic pipes or badly-bedded PVC pipes).

  • The Rotopuls nozzles are conceived to remove middle-hard deposits in pipes of plastic, steel or concrete

The enz manhole nozzles are specifically designed for cleaning shafts and vertical pipes. The forward facing water jets provide circumferential cleaning without stripes. The nozzles are self-centering during operation and do not have protruding parts that can cause the nozzle to become wedged on the access ladder. They clean with a front jet on the floor as well and require little space in the cleaning vehicle. Additional advantages include the manhole nozzles having no water loss from leaks and require practically no maintenance. The arduous cleaning with a hand nozzle or a lance is history with the manhole nozzle. Likewise, conical shafts can be cleaned easily.

The Chain scraper enz is an apparatus which has many uses and is simple in handling and maintenance. Several different pipe diameters can be cleaned with the same tool. Layers of mineral deposits and concrete residues are efficiently removed.

  • As preliminary operation before renovation with in-liners, coatings or by injections
  • Complete root removal
  • Removal of incrustations and deposits
  • Removal of concrete residues in newly installed sewage pipelines prior to inspection

These enz rotating cutters work without impacts. The cutter heads are equipped with hard metal plates, which are able to remove the most any kind of deposits. Their field of application is versatile. Layers of mineral deposits, concrete or concrete
sludge can be milled out with them as well as roots and wood.

  • Concrete or concrete sludge
  • Layers of mineral deposits
  • Roots, wood

These tools are a radical innovation for milling-off deposits in pipes. The enz impact milling cutters are designed to remove the most stubborn deposits like concrete, injection cement, mineral deposits etc. They work with a percussion system of 600-3000 impulses per minute and up to 12 tons of impact force.

  • To remove concrete, injection cement, calcareous layers etc.
  • 3.9 – 23.6 inch

The enz cutting ball works without impact, but has the ability to switch in vibration. The cutting ball is equipped with a hard metal front cut for pipes that are more than 50% clogged. The side blades are self-sharpening and maintain their sharpness over their entire service life. The cutting ball’s area of application is diverse. Due to its spherical shape it goes easily around curves without damaging the pipe. The cutting ball is leakage-free and can be operated with recycling water.

  • Interlaced roots
  • Mineral deposits
  • Lime scale

The enz guiding nozzles standard were developed specifically for targeted cleaning of pipe inlets. They are used in searching for connections in ground lines and can thus prevent the need for cleaning via a household connection, for example. Entrance into the connection is made using a head nozzle on a flexible hose.

  • For removal of loose rubble stone, gravel and soft deposits

The enz Bulldog rotating nozzle has been designed for operation with recycling water and fresh water. The cleverly built sliding bearing allows the use of every kind of recycled water. An integrated oil-free braking system results in a low wear and tear operation and in controlled numbers of rotation. In this way a most efficient and economic pipe cleaning is achieved. The bore of the nozzle insert determines the admissible size of the dirt particles up to a maximum 0.05 inch. Transport and water costs are noticeably reduced.

  • To remove fat, roots and harder incrustations
  • For operation with recycling water and fresh water

The nozzle enz KBRV is provided with 2 semi-radial jets directed forward in an angle of 45°. As a result, this nozzle must either be equipped with extra thrust jets or be mounted on a lance. The forward jets disintegrate most any residue and flush the debris ahead of the nozzle.

  • To remove plastic deposits
  • To clean heat exchanges
  • Cleaning of fat deposits
  • Flushing of the pipes from the house toward the main line
Sewer & Hydro Equipment

This all round enz combination nozzle is excellent for flushing out pipes as well as adjoining lateral pipes at any angle. It only requires a very small pump capacity and uses 2 radial jets at a 90° angle to the pipe wall and 2 semi-radial retro-jets at a 45° angle. This combination allows both, a forward thrust of the nozzle and simultaneously, a flushing away of the waste material.

  • To remove organic deposits
  • To clean heat exchanges
  • Cleaning of fat deposits
Sewer & Hydro Equipment

ENZ nozzles with forward impact angle of approx. 45° on the pipe wall as well as a front jet (on request) and 3 retro-thrust jets cause a cork-screw-like advance through the clogged pipe. While the front nozzles loosens and the semi-radial nozzles disintegrate the residues, the thrust nozzles are driving the nozzle head forwards and simultaneously pushing the waste material backwards.

  • Core-flushing of the steel pipes during hydraulic thrust-boring
  • Cleaning of house connecting pipework from inside to the drain system
  • Removal of ice in manholes
Sewer & Hydro Equipment

The semi-radial rotating enz nozzles with their 4 retro-acting cutting-jets at an angle of approx. 45° cause simultaneously the cleaning procedure and the thrust for the forward move of the tool i.e. the jets combine rotation and thrust in one function resulting in a low water consumption. With sufficient water capacity, optional thrust jets can facilitate upward cleaning.

  • Cleaning of pipes before TV-recordings
  • To remove mineral deposits in pipes
  • To remove roots up to 0.2 inch
Sewer & Hydro Equipment

The radial rotating nozzles enz are equipped with 4 radial jets of 75° for the pipe cleaning and 3 thrust jets for the advance which at the same time flush away the loosened residues. As a result, pipe ducts of all kinds, even with vertical boring etc., will be cleaned. The moving part of the enz nozzle rotates at a limited speed. These water jets hit the pipe wall directly with great impact, striking every corner, every dead end, every lateral pipe.

  • Cleaning of drain pipes
  • Cleaning of lateral pipes
  • Removal of solid deposits
Sewer & Hydro Equipment

Made of wear-resistant, hardened steel, provided with front jet insert and blind plug (interchangeable). Angle of jet backwards, sturdy wall thickness, long service life and a minimum of wear and tear.

  • Appropriate for removal of sludge deposits and clogging

Cleaning sewer lines when near home installations brings the risk of pressure equalization through toilets or stench traps. This comes from negative pressure arising ahead of the nozzle or excess pressure following the nozzle if the installation is not correct or venting is not working properly. It’s a very unpleasant surprise when this effect unintentionally turns a toilet into a shower! For this reason, enz collaborated with a prestigious technical institute to develop and test the Bulldog Antiblast. The Bulldog Antiblast prevents this unpleasant side effect and guarantees cleaning in all directions, right down to the pores.
