Advanced Torque Anchor from Evolution Oil Tools

The Evolution Advanced Torque Anchor (ATA) is a simple and reliable solution for preventing tubing back-off when using progressing cavity (PC) pumps. The ATA transfers PC pump torque to the casing walls. The bypass capability of the ATA is second to none. In most configurations, the ATA offers greater than 95% of the potential bypass available past a similarly sized EUE coupling. - See more at: http://eotools.com/index.php/component/virtuemart/276/1/artificial-lift/ata-advanced-torque-anchor-detail.html#sthash.BUmmnOAG.dpuf
