Application
The circular LKDC stainless steel manhole cover is used on top of tanks or containers, especially in the dairy industry, where a hygienic closeable mean of access to the interior of the tank is required.
Working principle
The LKDC cover is supplied with a unique replaceable, self-sealing double lip seal to prevent fluids from spraying out, e.g. during CIP cleaning and similar processes or during travel on mobile tanks or road tankers. The seals are produced in compliance with 3A recommendations.
