This is specially designed double mechanical seal having dry running faces and the success lies in selecting proper face materials and applying optimized seal closing loads on the faces. Secondly all surfaces which are coming in contact with fermentation media are buffed with mirror finish, offering an additional layer of protection against fluid leakage so that the surfaces undulations don't act as bacteria trap. To take care of any dislodged carbon particle which should not fall in the media, baffle arrangement is provided in the gland. Steam jacket is provided in the housing to keep seal area hot. Cold water also can be circulated so as to keep the sterility 100%. Suitable connections are provided in the gland and housing for steam sterilizing cleaning. The inboard is self-closing reverse balance seal series DD910.

A double dry mechanical seal, also known as a dual mechanical seal, is an advanced sealing mechanism designed to provide an enhanced level of sealing performance and reliability in industrial applications. It consists of two sets of seal faces and associated components, offering an additional layer of protection against fluid leakage.

Double dry seal is designed for fermenter & hygienic process vessels. The design does not allow entry of any external air to entry in the vessel even in case of leakage of inboard seal. Nitrogen gas is used as barrier / buffer fluid between the two seals. Seal Gland & Housing is specially designed for cold water circulation for remove of heat. Seal warranty is for 2 years continuous working.

It's worth noting that the design and configuration of double dry mechanical seals can vary depending on the specific application requirements. Factors such as fluid characteristics, operating conditions, and industry standards need to be considered when selecting and implementing these seals. Consulting with experts or manufacturers is recommended to ensure the proper design and installation of double dry mechanical seals for a particular application.
