XK-100 Power Swivel
In 1999, we launched our first power swivel - the XK-90 with NO GEARS.
By 2008, with its high tonnage and torque ratings, it had become the preferred power swivel by well servicers around the world.
By 2015, the design had evolved to the current XK-100 with 7000 ft-lbs torque and a 100-ton load rating.
Along the way, we developed many other unique and patented features including power tilt, 10,000 psi washpipe seal assembly, a total of only 4 hydraulic hoses, a powered 4-hose reel, and an optional air brake. Our patented safety valve is also included to prevent downtime from blown shaft seals if someone forgets to hook up the drain hose.
XK-150 Power Swivel
The XK-150 was launched in 2000, also with the simplicity of no gears. With 12,000 ft-lbs torque and 150 tons capacity, the XK-150 is just right for deep service jobs.
Not only used for heavy well servicing, the XK-150 has also been used for low cost drilling. For 15 years one customer drilled vertical wells to 7,500 feet, then horizontal out to 7,000 feet. Although normally top drive work, he has been very successful using this low cost approach without a torque track or pipe handling functions.
Like the XK-100, along the way we developed many other unique and patented features including power tilt, 10,000 psi washpipe seal assembly, a total of only 4 hydraulic hoses, a powered 4-hose reel, and an optional air brake. Our patented safety valve is also included to prevent downtime from blown shaft seals if someone forgets to hook up the drain hose.
XK power swivels include our patented power tilt function. Our customers are very pleased with the safety benefits and time savings.
Here's how it works. At rigup, the driller tilts the swivel to match the catwalk pipe angle. He then adjusts and locks the stop bolt to set that angle. Then each time the valve handle is moved to its detent position, the swivel tilts to that angle. The driller does not have to hold on to the valve handle, he just moves it to the detented position and lets go.
When tilt is not in use, the power swivel is hydraulically held in the vertical position without rope or chain.
Only four hydraulic hoses are required for all swivel operations, all on one hose reel.
High Pressure Seal Assembly
Our patented seal assembly is rated at 10,000 psi. It is automatically pressure-lubricated and requires no manual greasing. Uniquely different than any other sealing concept, this is a highly engineered and patented approach.
Our seal assembly has been lab-tested at 7500 psi for 1000 hours, but we all know that lab testing is not field testing. After two years in the field, we are excited that reports are already at 500 hours seal life. We continue to improve the design, and when field data can be collected, we expect more than 1000 hours of seal life before replacement.
