LAMPE Sewer Sealing Cushions with double cone - the original for over 40 years!
Already in the 70s we, the company LAMPE GmbH, invented our non-stretchable Sewer Sealing Cushions with double cone, which have established themselves as the safest and most economical pneumatic pipe stoppers and bladders. Until today, all of our Sewer Sealing Cushions have been manufactured 100% directly in Germany in our company.
In comparison to conventional stretchable pipe plugs or bladders, our non-stretchable Sewer Sealing Cushions with double cone offer some big advantages which make these devices much safer and more economical than pipe plugs or bladders.
- LAMPE Sewer Sealing Cushions require no additional bracing
- Our Sewer Sealing Cushions are suited for all types of pipe cross sections: e.g. ovoid, kite- shaped, rectangular, etc
- LAMPE Sewer Sealing Cushions can provide extremely long service life (Over 40 years proven!)
- One device can be used in various diameters
- LAMPE Sewer Sealing Cushions are repairable
- LAMPE Sewer Sealing Cushions feature very lightweight and compact design
- All sizes up to 2,200mm can be introduced into the sewer system through a normal sized manhole.
The advantages of our non-stretchable Sewer Sealing Cushions are absolute unqiue:
LAMPE Sewer Sealing Cushions require no additional bracing
As already mentioned, our Sewer Sealing Cushions don´t work with material strechting. Our Sewer Sealing Cushions are already fully applied to the pipe wall to be sealed when fully filled, far below the required working pressure of 1 bar. Therefore even a significant drop from the nominal working pressure will not impair the contact with the pipe wall and the cushion will not move in the pipe.
Therefore, our Sewer Sealing Cushions do not require an additional bracing, as there is always enough time to control a possible pressure loss and to regulate it if necessary. Stretchable pipe plugs, on the other hand, shrink very quickly even at low pressure losses and therefore lose contact with the pipe, so that the accumulated water sets such a pipe plugs in motion very quickly, which makes working with stretchable pipe plugs very dangerous. This is why it is absolutely necessary to brace stretchable pipe plugs to prevent a motion of this devices.

LAMPE Sewer Sealing Cushions can be used in various pipe diameters.
Although our Sewer Sealing Cushions do not work with material stretching, they can still be used in various pipe diameters. This works according to the principle that the Sewer Sealing Cushions are simply folded together in smaller diameters, whereby the conical shape of the Sewer Sealing Cushions plays an important role.

LAMPE Sewer Sealing Cushions made of CR provide extremely long service life.
Due to the fact that our Sewer Sealing Cushions are made of pure CR (neoprene), without any plasticicers, they are subject to practically no ageing, as they do not embrittle, like simple rubber pipe plugs or bladders. We can prove lifetimes of our Sewer Sealing Cushions of over 40 years!
Our Sewer Sealing Cushions are suited for all types of pipe cross sections.
Due to the non-stretching principle and the conical design, they can be used for any pipe cross-section. Whether oval profile, mouth profile, box profile, kite profile or special profile with dry weather drain: we have the right Sewer sealing Cushion for every pipe!
LAMPE Sewer Sealing Cushions are reparable.
This advantage is based on the fact that the Sewer Sealing Cushions do not work with stretching, which means that there is no danger of a repair being made. In addition, the devices are cold vulcanized, i.e. glued in a special "gluing process" in which a chemical process bonds the glued individual parts together as one part. This means that the repair process is similar to the manufacturing process of a new device. A stretchable pipe plug or bladder, on the other hand, cannot be repaired.
In addition, all LAMPE Sewer Sealing Cushions feature lightweight and compact design.
Even our large devices up to 2,8m can be folded so tightly that they can be introduced into the sewer system through a 600 standard manhole.

For the proper operation of our sewer sealing cushions it is absolutely necessary to use our original accessories: Safety fitting 1 bar Art. 71427, filling hose e.g. 10 m Art. 71525 as well as accessory for the primary pressure (e.g. pressure reducer). The use of any other foreign filling-equipment is forbidden, because of the different working-pressures of other pipe plugs and pipe stoppers!
