The MECO AH Type-2 model is the best choice for fitting a split seal in limited space on small to large shaft diameters. The configuration is a double mechanical seal using an elastomer drive to rotate bearing-grade synthetic seal faces against fixed, stainless steel seal faces. The AH Type-2 uses a barrier fluid to pneumatically load the seal faces and isolate the process from the atmosphere. The AH Type-2 is suited for MRO and OEM equipment.
When Are AH Seals The Best Option?
The MECO AH Type-2 seal model is the answer to the question, "How can we fit a split or unsplit face seal in the existing space?" The seal model is used on horizontal, inclined and vertical shafts. The seal design is applicable when an inert barrier fluid is required to isolate the process from the atmosphere. They are used on blenders, bucket elevators, some polymer extruders, and both ends of a screw conveyor. Two unique configurations following the core principles are available. The seal may be designed to fit between the gear reducer and trough end of a screw conveyor, as shown below.
