Bypass Sewer Sealing Cushions – Our 2000 Series

Our 2000 Series, while providing virtually all benefits associated with our double-cone LAMPE sewer sealing cushions, also incorporates an integrated bypass pipe. This allowing water to be passed through the cushion without the need for pumps. The water flow is driven entirely by gravity – i.e. only by means of a downward slope – through the bypass pipe within the sewer sealing cushions. Depending on the size, the bypass cushions are suitable for bypass pipes with a diameter of 100mm to 500mm (3.9 " to 19.7"). This pump-free water transport saves you both time and money.

If the flow needs to be temporarily shut off completely, this can be easily achieved by inserting a smaller LAMPE sewer sealing cushion into the bypass pipe. This closure can be quickly reopened again at any time to let water flow through the bypass pipe, i.e. to allow the flow to pass through a jobsite while keeping it safe and dry. If required, the bypass line can be extended using additional pipe segments to accommodate very long jobsites.
