Flexible tank covers for hygienic applications

13 January 2020

Alfa Laval tank covers provide a visual inspection or entry solution for tanks. For hygienic processes, the company offers a range of 3A approved inspection and personnel entry ports with a variety of surface finishes and seal materials. 

The tank covers securely fit the openings of high, low or non-pressure tanks, both above and below the liquid level. For hygienic processes, there are two models. The oval-shaped LKD stainless steel tank cover is used on tanks or containers in hygienic applications. For inspection purposes the cover can then be turned into the tank. For personnel entry, the cover can either be removed at the double hinge or swung out of the tank. The seal is hygienically positioned and is not affected by positive or negative pressure in the tank.

The circular LKDC stainless steel tank cover is used on top of tanks or containers. It is supplied with a replaceable, self-sealing double lip seal to prevent fluids from spraying out, for example, during CIP cleaning and similar processes.

The small and mid-sized LKD and LKDC inspection ports and the larger personnel entry ports are now approved in compliance with the American 3-A Sanitary Standard and the U.S. Food and Drug Administration (FDA) Declaration of Conformity. 3.1 Material Certification in accordance with EN 10204 is supplied with the covers.
