The only moving parts are the hydraulic motor, stem, and packing cartridge. Using a 5000 psi piston-type, hollow shaft hydraulic motor, the swivel stem is driven directly by a massive lubricated spline.
The XK-150 packing cartridge is designed to have the big packing nut on top and non-rotating. This allows the non-rotating packing to be greased while drilling with an air-powered greasing system. This can extend packing life dramatically during difficult drilling situations.
Available lifting devices include elevator type bail or CobrahookTM link hooks,which allow wire line lubricator access to the gooseneck top connection for horizontal drilling work.
