SEWER SEALING CUSHIONS Variable use for sewage - and rainwater pipes in case of: repair works, sewer inspections, relining and pressure tests
Unique advantages and benefits
Quality and Safety - tested and certified.
SIMPLE . SAVE . TIGHT LAMPE sewer sealing cushions are self-fixing in a normal clean pipe In the publication BGI 802 (Procedural Instruction for the work with provisory Exactly these criteria are fulfilled by LAMPE sewer sealing cushions! Differently from traditional, expanding pipe plugs, our devices join already at a very low pressure (0,01 bar) - which lies far below the prescribed working pressure of 1 bar - completely to the surface of the sewer. In case of an eventual pressure loss, our devices will not contract, but they will continue to join to the sewer wall and keep the accumulated water head. So, only the cushion would become softer and the accumulated water on the bottom of the sewer -under the not moving cushion- may drain off. Traditional, expanding pipe plugs however work on the principle, that they will expand when they are inflated. Only after the devices have expanded under pressure they will join to the sewer wall. In case of a not foreseeable pressure loss of these devices the contrary would
High resistance against ageing and good resistance against chemicals LAMPE sewer sealing cushions are cold vulcanized out of a 100% pure CR (Neoprene) coated material, that means, the devices are glued by applying a special procedure. This manufacturing process needs no admixtions of foreign substances like softeners or sulphur! Therefore LAMPE sewer sealing cushions never spread! Our devices reach a lifetime of more than 30 years! That you cannot await from traditional pipe plugs. Traditional plugs are always made of hot-vulcanized synthetic rubbers like e.g. SBR, i.e. the materials are pressed in shape by adding heat and pressure. The hot vulcanization however requires the addition of foreign substances to the original material like softeners or sulphur. These foreign substances escape out of the original material after a certain time (5-10 years, depending on its frequency of use and storage). So, such a normal pipe plug will become one day air-permeable and it will spread (rubber effect). Once this has happened, the device must be replaced. SEWER SEALING CUSHIONS All LAMPE sewer sealing cushions are repairable A great advantage of all LAMPE sewer sealing cushions! Because our cushions are not working with expansion it is quite easy to repair them cost-effectively with patches out of the same material. No expansion has to be considered when repairing the cushions. Traditional pipe plugs cannot be repaired with a patch, because these plugs are working on the expansion principle and the repaired spot had to show the same expansion capacity like the basic body. As this is not possible there would arise there a very dangerous weak spot.
One device shuts many different diameters Although our sewer sealing cushions are working without expansion they can be used for a lot of various pipe diameters. Why? Let us take for example the type 1-1400: This device has a utility range of 500 up to 1400mm. if you blow this cushion up outside the sewer wall, then you will receive already the maximum diameter of 1400mm. If you prefer to use this device in a smaller sewer, e.g. DN 500 or 600 you only have to make a fold on the left and right side of the cushion and make sure, that here the material overlaps. Now you have a smaller "package“ which can be pushed into the smaller pipe. The cushion now disposes over more material than what is needed to shut the canal. If you are now inflating the cushion, the remaining material will close these folds again. That’s the trick why LAMPE sewer sealing cushions can be used in a lot of various diameters. Traditional sewer plugs never offer such large ranges of coverage! One LAMPE sewer sealing cushion for all profiles Our devices may be used in all imaginable profiles, for example for egg, mouth or rectangular profiles. This is the result of our special construction which enables the material always to adjust itself entirely to the sewer wall. Normal sealing plugs can only be used for round pipes. For other profiles special devices are necessary. All devices can tightly be folded and are low of weight. The device 1-1400 which can be used for up to 1400mm, weighs e.g. only 25 kg! Therefore it can be handled very easily and fast! Traditional pipe plugs of similar sizes weigh significantly more! But also the possibility to fold the cushion r'epresents an enormous advantage. Even cushions of the type 1-2200 (1000 up to 2200mm) may thus be pushed through any common manhole (620 up to 630mm)! WORLDWIDE MARKET LEADER Patented, fixed special sealing allows absolutely air and gas-tight sealings for pressure tests The operating principle of the LAMPE sewer sealing cushions bases on a special folding of these devices. When developing the devices more than 30 years ago, we were confronted with the problem, that the builded folds were not 100% air-tight. Thus the normal devices were absolutely not suited for pressure tests. Then we developed a special sealing of foam rubber which always seals the developing folds absolutely tight due to its special compressibility. Many years of experience in the area production and in handling sewer sealing cushions proved, that only devices with fixed special sealing rings may seal a canal herme-tically against air and gas, what is absolutely necessary when performing a pressure test with pressure or vacuum.
LAMPE sewer sealing cushions Series 2000 These special devices with pipe bypass maintained most of the advantages of our devices with double cone, but offer additionally the possibility of the geodetic water transport through the cushion. Water can be directed automatically through the cushion by using a PVC-pipe which is located in the middle of the cushion and that without having to use a pump. In case of need the inner pipe may also be extended in order to direct the water also over a longer route through the construction site. If you wish to shut the canal entirely, you can of course also shut the inner pipe with a traditional sewer sealing cushion. The advantages are obvious: Time saving by simple handling, cost reduction because no pumps are necessary (a head will do), more flexibility e.g. in the open excavation site with pipe extensions.
