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.

LAMPE's KAS sewer shut-off system provides immediate, reliable sewer line closure as required in response to hazardous liquid accidents or to hold back fire-fighting water.

The KAS sewer shut-off system, a permanently installed "pneumatic gate valve", is expertly engineered to prevent accident-related environmental pollution by hazardous substances such as automotive fuel, heating oil, chemicals and used (i.e. potentially contaminated) fire-fighting water.

The KAS basic device is a wide, full-circumference double-tube system which is mounted in a close-fit position on the inner surface of the host sewer pipe. In the event of an alarm (for example when fire-fighting water must be held back) the double-tube system is inflated to the precise dimensions required to hermetically seal off the host pipe. The shut-off device is activated either manually from a pneumatics station located above ground or by automatic or remote control.

This system reliably shuts down wastewater or stormwater outlet sewer lines in response to hazardous liquid accidents or to hold back fire-fighting water. To ensure satisfaction of the customers' personalized requirements, each LAMPE sewer shut-off system is custom-designed and manufactured for the specific application at hand.

Delivery, installation, commissioning and instruction of the customer's operating personnel are carried out by our specialists, providing the basis for reliable operation of the system as well as flexible implementation in exact accordance with the customer's requirements.

The KAS sewer shut-off system provides a number of convincing advantages over gate valves:

  • Cost savings due to problem-free retrofit installation.
  • No additional earthworks required for installation.
  • Low costs for subsequent maintenance and servicing.
  • Entrained foreign materials such as stones, branches, etc. do not impair operation.
  • Easy to operate.
  • Long-term, trouble-free operation over many years' time, a significant advantage over mechanical gate valves.

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.

Operation:

  • Pneumatics station
    The pneumatics station containing the pneumatic controls and the compressed air supply is housed in a steel cabinet located at ground level, approx. 3 – 4 m (11 ft) from the access manhole.

  • Filling line
    The filling line conveys compressed air from the pneumatics station to the KAS basic device installed in the sewer line.

  • KAS basic device
    The basic device of the KAS  technology is a wide, full-circumference double-tube system which is inflated with defined pressure to securely seal off the host sewer pipe. It is made from a rot-proof, neoprene-coated material.
