The Huhnseal BC-series is a new type of seal designed for various heavy duty applications where durability is key. This is a robust, reliable and cost effective seal suitable for standardization in larger process industries but also for customers with more limited amounts of equipment. During the development of the BC-series the main focus has been on adaptability to different pressure and speed conditions, reliability and ease of installation. The BC is a double balanced seal that handles pressure drops on either product or barrier/buffer sides and effectively minimizes heat generation at the seal faces. Designed to fit most standard equipment / Suitable for standardizing / Robust and durable design / Ability to handle pressure fluctuations / Easy to install.
The seal can move ± 2,0 mm independent of the compression of springs. The seal follows the movement of the shaft without influencing the compression of springs. This feature is essential when sealing equipment with flexible bearing units.
The springs are located in the area circulation and the exchange of barrier fluid is the greatest. This eliminates the risk for clogged-up springs, which is one of the most common causes for seal failure.
Four different ways to connect the flushing media to the flange. Axially, horizontally or a mix of both. This feature facilitates the installation of the seal in confined spaces and allows for obstructing equipment to be bypassed.
The flange configuration with inboard cover. This reduces the cost of the seal by lowering the amount of expensive material potentially in contact with abrasive or corrosive media.
The seal is double balanced using a “floating” o-ring design. This enables the seal to handle sudden pressure variations. This also makes it possible to reduce heat generation.
The seal faces used on the product side can also be used on the atmospheric side. This allows for all internal parts to be used on both sides for high standardization purposes.
