Power Swivels
The only moving parts are the motor, stem, and packing cartridge. All models use one high torque, hollow shaft hydraulic motor which drives the swivel stem directly through a massive lubricated spline.
No gears are used, so motor speed is swivel speed - very low by hydraulic standards, and very good for long life. This also means service is easy, allowing the entire hydraulic drive including swivel shaft bearings and seals to be removed by simply unbolting and pulling it off the stem.
The XK Power Swivels also have unique lubrication and sealing features. Shaft bearings and seals are either pressure-lubricated with hydraulic oil or are pressure-greased, and all seals run on wear bushings to prevent stem wear and corrosion. The XK's also include our special safety valve which prevents downtime from blown shaft seals in the event the drain hose is disconnected or blocked. Our swivel with this valve was awarded U.S. Patent 6,659,127.
