Custom Shaft Seals

If you suffer from painful shaft sealing problems like axial shaft motion, thermal growth, repetitive pressure-vacuum cycles, and harsh chemical environments, its time to call the MECO-DR. The MECO-DR is a patented driving mechanism, for use in Meco shaft seals. 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 (1/4 and more) runout/ misalignment tolerance No internal springs to corrode or break Economical, on-site rebuilds Developed for Moyno? progressing cavity pumps, the MECO-DR is now available for mixers, blenders, reactors, dryers and other process machinery. The seal is spring-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.Moyno? is a registered trademark of Robbins & Myers, Inc. Designed for Performance; Customized for Your Needs--------------------------------------------------------------------------------MECO-DR stuffing box insert seals for Moyno? pumps When Robbins & Myers Corporation asked MECO to deliver a mechanical seal that would last as long as their rotor/stator combination in abrasive slurry service, the MECO-DR was born. Three years of development and field testing produced a robust seal that outlasts two and more sets of pumping elements in extremely abrasive applications.Utilizing massive cross sections of high-tech wear material, the MECO-DR doggedly withstands determined assaults from kaolin paper coating, sheetrock mud, hazardous waste, and even white chocolate confectioner's frosting.The MECO-DR survives vacuum conditions and pressure spikes without complaint. Available in pneumatically-loaded or spring-loaded configurations, the seal constantly adjusts itself for sacrificial face wear, and recovers quickly from pressure surges which would devastate lesser seals.Often, mechanical seal installations seem like delicate surgical procedures. The MECO-DR is built to be installed and operated by ordinary human beings: installation is simple, and the sacrificial seal faces can be freely handled - even dropped - without damage. The seal's faces even withstand hammer blows during installation.Call your MECO distributor for more information on how you can extend your PC pump service life with the MECO
