Cement Swivel

Where pumping cement through the top drive is to be avoided, the Volant CST Cement Swivel provides a means to introduce cement below the top drive and provides the option to rotate the casing string during cementing if desired. The Volant CST allows cement to be pumped in through one, or both, of its dual side-entry ports and offers a 10,000 psi pressure rating. With no welded joints and a robust seal design, the Volant CST offers a long wear life and reduced maintenance requirements due in part to its self-cleaning internal geometry.

  • Compatible with both Volant’s CRTi® and CRTe® casing running tools and Plug Launcher for increased cementing efficiency.
  • Circumvents need to pump cement through top drive eliminating risk of cement setting in the top drive components.
  • Rotation and reciprocation of casing string improves integrity of cement job.
  • Able to pump cement through one or both inlets if high pressure is not required.
  • Robust seal design offers a long wear life and reduced maintenance requirement.
