Type 270A, 301A, 323A

Types 270A, 301A, and 323A are cartridge seals that have been specially developed for the large seal chambers („big bore“) of the ANSI | ASME B73.1 M… standard. What is particularly positive about this standard is that a clear distinction is made between the installation of packings and mechanical seals. The size of the packing chambers corresponds to the traditional dimensions, however, the mechanical seal chamber was recommended to be larger in accordance with the requirements of the mechanical seal, in some cases even with conical chambers. This development of the industrial standards and recommendations is to be welcomed, as the lifetime of mechanical seals can thus be significantly prolonged.
