LAMPE GmbH: Your specialist for pipe sealing techniques (pipe plugs, Sewer Sealing Cushions and bladders)

You are looking for pipe plugs, Sewer Sealing Cushions or bladders for pipe sealings?

This is the right place for you! You can buy your pipe plugs, sealing cushions and bladders directly from the manufacturer and inventor of the conical Sewer Sealing Cushions.

For over 40 years we, LAMPE GmbH from Stadtoldendorf, have been developing and manufacturing shut-off products such as pipe plugs, bladders and Sewer Sealing Cushions. In addition to mobile shut-off technology, we also offer a fixed installed shut-off solution als an alternative to mechanical gate valves and pneumatic rescue equipment such as lifting bags.

We developed the most innovative and successful product from our company over 40 years ago:
Our conical LAMPE Sewer Sealing Cushions.

LAMPE Sewer Sealing Cushions: More economical, easier to handle and safer than conventional pipe plugs.

Compared to a conventional, stretching pipe plug and other rubber bladders, these devices offer some enormous advantages, which make their use much more economical, easier and above all safer:

LAMPE Sewer Sealing Cushions do not require an additional bracing.

This means that they do not have to be additionally braced against movement. A conventional pipe plug, on the other hand, must always be additionally braced.

LAMPE Sewer Sealing Cushions can be used in different pipe profiles.

Conventional pipe plugs can only be used in round pipes. Our Sewer Sealing Cushions can also be used in ovoid, rectangular, kite shape and any other special pipe profiles.

LAMPE Sewer Sealing Cushions have a very long lifetime.

Our conical Sewer Sealing Cushions, made of neoprene offer a much longer lifetime than conventional pipe plugs made of rubber.

LAMPE Sewer Sealing Cushions are repairable.

If, on the other hand, a conventional pipe plug is damaged, these devices almost always have to be purchased anew and cannot be used any more.

LAMPE Sewer Sealing Cushions feature very lightweight and compact design.

LAMPE Sewer Sealing Cushions fit through small manholes and allow an easy handling.

A larger conventional pipe plug usually does not fit through a normal standard manhole any more and can therefore only be introduced very difficulty into a sewage - or rain water - pipe. Our devices up to 2.200 fit through normal manholes.

A single Sewer Sealing Cushion can be used to close of various pipe diameters.

Each individual device can be used in many different diameters. Conventional pipe plugs normally have shorter diameter ranges.

Our performance and our service as manufacturer and inventor.

Aside from the pure product advantages of our Sewer Sealing Cushions we offer:

  • Individual products for special solutions
  • Fast delivery times
  • Extremely fast reaction times to your enquiries and demands
  • Product and handling trainings
  • Deliveries worldwide through our large network of distribution partners
