DS - Model BL-R Series -Pipe Sealing Systems

• DS BL-R is in accordance with the requirements of DIN EN 681-1 / DIN 4060 [88] (seals made from elastomers) and the FBS quality guideline
• DS BL-R pipe connections fulfill the criteria of DIN EN 1916, method 1-4.
• DS BL-R can be easily connected with the pipe. It is mounted on the base ring and is anchored during manufacture of the pipe in the pipe socket. After removal of the base ring the DS BL-R socket is ready for installation
• DS BL-R can be used for all pipe production machines with core vibration and radial pressure roller head.
• DS BL-R requires special base rings, which determine, by their shape, the seat of the seal.
• DS BL-R can be supplied for pipes DN 150 to DN 2600 in 6 specific cross sections.
• DS BL-R lines the inner wall of the socket up to the socket face. Lining the entire socket space prevents deposits of dirt and water (ice formation) behind the seal. Removal of a protective strip is not required.
• DS BL-R pipe connections resist high shearing forces.

• forms an integrated unit together with the pipe, which enables a quick and safe laying.
• the wedge shape of the seal body eases the pipe centering.
• thanks to the fully lined sleeve, the pipe connection offers an optimum sealing unit.

DS BL-R is produced from styrene-butadiene rubber (SBR), hardness 50 ± 5 IHRD. The material resists the usual stresses caused by sewage.
