Lampe 'KAS' Sewer Pipe Sealing System
Reliable Environmental Protection
The Lampe KAS sewer pipe 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 contaminated fire fighting water.
The Lampe KAS sewer shut-off system provides immediate, reliable sewer line closure as required in response to hazardous liquid accidents or to hold back contaminated 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.
How It Works
The Lampe KAS sewer shut-off system can be installed in existing or new stormwater or mixed-water sewer pipes.
In the event of a retrofit installation in existing sewer pipes, costly and time-consuming groundwork 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 incident, 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 pneumatic station, by remote control or automatically by installed 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 system. As a result, long service life is assured and maintenance costs are extremely low. Offering a unique combination of reliability, efficiency and high durability, the KAS sewer pipe sealing system is the only one of its kind worldwide.
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 incident (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 pneumatic station located above ground, automatic detection or by remote control.
This system reliably closes off wastewater or stormwater sewer lines in response to hazardous liquid accidents or to hold back potentially contaminated fire fighting water. To ensure the installation fits the exact needs of the customer, each Lampe KAS sewer line shut off system is custom designed and manufactured for the specific application at hand.
Delivery, installation, commissioning and training of the customer's operating personnel are carried out by our specialists. This provides the basis for reliable operation of the system in exact accordance with the customer's needs.
The KAS sewer line shut off system provides a number of convincing advantages over other gate valves:
- Cost savings due to problem free retrofit installation.
- No additional groundwork 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.
