Drive mechanism increases seal integrity
Meco engineers have developed a new, patented drive mechanism, which augments the sealing capabilities of Meco seals.
Meco engineers have developed a new, patented drive mechanism, which augments the sealing capabilities of Meco seals Used in place of a driving elastomer, the enhanced mechanical drive system allows the EAS seal to accommodate demanding conditions such as thermal growth, variations in process pressure, highly viscous materials, hostile process chemistries and severe abrasives

Shaft seals for bulk and powder processes
Meco AH-series custom seals are designed to simplify installation, routine cleaning and maintenance.
The Meco-DR allows the rotating seal faces to compensate instantly for axial shaft motion, without affecting seal face loading.
And the Meco-DR retains all of the superior characteristics of original Meco elastomer-drive seals: fully-split designs, high (6mm and more) runout/misalignment tolerance, no internal springs to corrode or break and economical, on-site rebuilds.
Originally developed for Moyno progressing cavity pumps, the Meco-DR is now also available for mixers, extractors, reactors, and other process machinery.
The seal is either spring or pneumatically loaded from the outside, so that seal face pressures are constantly adjusted to compensate for wear of the sacrificial seal faces.
The Meco-DR can withstand punishing abrasives and keep on running, long after conventional seals have failed.
The Meco-DR is available as a design feature in new Meco seals, and also as a retrofit for some existing EAS, Meco-Pac OR Ex-Pac seals. Request a free brochure from Meco Shaft Seals ...
