SHAFT SEALS
- Hybri-Seal® is the sealing mechanism containing a standalone cartridge assembled in each cover plate. Depending on the application of airlock, customer can choose from different types of cartridges (shown in figures below) that provides a combination of packing seals and high strength U-cup lip seals with an option for air purge to enhance sealing performance of airlock. Numbers of seals arranged in cartridge is almost twice as many as provided in other airlocks along with polished shaft helps achieve increased life for seals.

VALVE DIMENSIONS
VALVE SELECTION GUIDELINE
The valve capacity for any given valve size listed in following table is based on assumption of 80% pocket fillage. In practice, this can vary based on the material to be processed (product characteristics), pressure differential at valve, RPM of the valve and feeding method as all of them affect the valve throughput efficiency.
Example:
Customer requirements: 10 Tons/Hr.
Product density: 50 Lbs/Cubic Feet
Volume capacity required: (10 x 2000 Lbs./Hr.) / (50 Lbs./Cubic Feet) = 400 Cubic Feet/Hr.
From the Valve capacity chart below, customer can choose 10 inch valve size with 15 RPM yielding 418 Cubic Feet/Hr. Customer can also choose higher capacity valve with lower RPM depending upon customers’ other requirements.
To ensure proper selection of the airlock size, speed and other configurations, please fill out the data application sheet or talk to our application engineer.
