LAMPE KAS Sewer Sealing Systems – "The Better Gate Valve" for Hazardous Liquid Control and Fire-Fighting Water Retention
The pneumatic alternative to mechanical slide valves, gate valves and butterfly valves for environmental protection and retention of fire-fighting water.
The LAMPE KAS sewer shut-off system, also known as the "pneumatic gate valve", provides a cost-efficient and highly effective solution to one of the toughest environmental problems facing industrial manufacturers today - quick-response shutoff of wastewater and stormwater sewer pipes in the event of hazardous liquid accidents or for retention of fire fighting water.
A number of big-name manufacturers including Audi, BASF and Volkswagen have decided to go with this advanced technology and the advantages it provides over conventional gate valves in hazardous liquid containment and retention of fire-fighting water. More and more companies are deciding to go with this technology as shown by the ever-growing number of users listed in the "References" section of this website.
The LAMPE KAS Sewer Shut-Off System / How It Works
KAS – simple, extremely fast pipe sealing
The LAMPE KAS sewer shut-off system can be installed in existing or new stormwater or mixed-water sewer pipes.
In the event of retrofit installation in existing sewer pipes, costly and time-consuming earthwork is not required since the KAS basic device can be installed in the sewer line by accessing from the nearest manhole shaft.
It is firmly mounted in a close-fit position on the inner surface of the host sewer line, reducing the pipe diameter only by approx. 7 mm (0.3 in) and therefore not restricting water flow when not inflated. Entrained foreign materials such as stones, branches, etc. do not impair operation as the KAS sealing cushion, when inflated, expands around these objects and still closes off the line very securely.
In the event of an alarm, the KAS basic device is rapidly and reliably inflated to a pressure of < 1 bar (< 14.5 psi), therefore closing off the host line. The device is actuated either manually from a pneumatics station, by remote control or automatically by means of sensors or fire detectors.
The system has no components which are fragile or subject to mechanical wear and utilizes rot-proof neoprene as the material of construction for the KAS sealing cushion. As a result, long service life is assured. Maintenance costs, on the other hand, are extremely low. Offering a unique combination of reliability, efficiency and high durability, KAS is the only system of its kind worldwide.
