High-pressure jetting equipment is used to clean everything from surfaces to tubes, sewers and pipes. There are several challenges that jetting equipment operators may come up against, from tree roots to debris, and concrete inflow. However, having the right nozzle for the jetting hose is half the battle won.
This is why Werner Pumps SA, leading South African design, manufacture, supply and maintenance specialist in high-pressure jetting equipment, has partnered with Enz Technik AG to supply Swiss-manufactured nozzle solutions. “Enz has been servicing the jetting market since 1985 and the company’s high-tech products are unsurpassed when it comes to workmanship quality and effectiveness,” says Sebastian Werner, MD of Werner Pumps. “We stock a comprehensive range of Enz nozzles that are compatible with our 100% locally manufactured jetting and vacuuming equipment, as well as other models available in the South African market.”
The philosophy at Enz is creating “products that clear the way” and “the optimal piece of equipment for every application”. Some of the specialist Enz products available from Werner Pumps include:
- Rotopuls: The Enz Golden Jet rotating nozzle is provided with an eccentrically supported rotor, which produces very fast vibrations and pulsating jets. The resulting pulsations are strong enough to disintegrate deposits up to 10cm thick. 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.
- Bulldog: The Enz Golden Jet 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, ensuring efficient and economic pipe-cleaning. The bore of the nozzle insert determines the admissible size of the dirt particles, up to a maximum Ø 1mm.
- Pointed nozzles: Concentrated powerful advance is obtained by means of four front jet nozzles. The sharp edges cut, break and penetrate through every kind of blockage. Made of wear-resistant, hardened steel, all nozzles from art. 60.050 onward are provided with ceramic inserts. Because of this, the efficiency is considerably higher compared with those nozzles with drilled holes and the service life is several times longer. Applications include penetrating of completely clogged pipes, opening of interlaced roots and opening of frozen pipelines.
- Grenade bomb: This Enz Golden Jet nozzle is made of wear-resistant hardened steel. The “grenade” and the “bomb” are joined in the same nozzles. Two different jet angles of 10° and 30° perform together, ensuring strong traction and effective cleaning. Applications include removal of loose rubble, stone, gravel and soft deposits.
- Ejector nozzle: These tools are outstanding in their enormous flushing capacity. Their main application is cleaning large fully surcharged pipes and drains bigger than Ø 500 mm. The specific arrangement of the nozzle inserts ensures that the nozzle jets do not work directly against the pipe wall. As a result, this tool is also appropriate for cleaning older channel systems.
- Pipe cleaning nozzles: Designed specifically for cleaning clogged pipes, this range of stainless-steel nozzles offers centric front jet and three or four rear jets (30°). The front jet penetrates completely clogged pipes and frozen pipelines, while the rear jets flush away the waste material.
- Chain flail heads: These nozzles are used to clear calcareous layers, concrete residues and larger roots.
- Bulldozer nozzles: Used to clear heavy blockages of sand, rags, plastic bags, containers and rocks. It has a front nozzle to clear its way.
- Impact cutter heads: A radical innovation for milling of deposits in pipes, these nozzles have carbide-tipped teeth to remove most stubborn deposits, such as thick roots, calcareous layers and injection cement. They can also be equipped for use in plastic pipes.
- Spinning nozzles: Used in drains and sewer lines to blast blockages such as fat, calcareous deposits and smaller roots. This nozzle can also be set to 1000-bar for boiler tube cleaning and removal of hard scale.
- Cross-jet nozzles: Used in the cleaning of boiler tubes and heat exchanges, as well as completely blocked pipes. This tool is able to cut hard scale from within these tubes.
