MECO-Pac Series Seals - The MECO-Pac is an elastomer-driven, MECO seal designed to replace packing in stuffing boxes.
- It is used primarily in airlocks and rotary valves, where no installation clearance exists for an externally
mounted seal.
- The MECO-Pac seals on a plane perpendicular to the shaft, eliminating abrasive damage to the shaft caused by packing
or lip seals.
- The MECO-Pac has proven effective in maintaining pressure differential across airlocks, without the frequent adjustments
required by packings.
- Available in several materials for service in a wide variety of products including: food and pharmaceutical
products, abrasives, and hazardous and toxic materials.
- The MECO-Pac requires a minimum 3/8" packing section, a minimum bore depth of 1.313", and an air or gas purge of
approximately 1/2 CFM at 3-5 psig.
- MECO-Pac seals should only be used in applications where there is no possibility of installing an external seal.
