In 1999, our XK-90 power swivel launched with the simplicity of no gears.
By 2008, with its high tonnage and torque rating, it had become preferred by well servicers around the world.
Constant Improvement & Innovation
By 2015, it had evolved to become the current XK-100 with 7000 ft-lbs torque and a 100-ton load rating. Many other unique features include power tilt, 10,000 psi washpipe seal assembly, powered 4-hose reel which handles hydraulic hoses, and optional brake. It also includes our patented safety valve which prevents downtime from blown shaft seals if someone forgets to hook up the drain hose.
20 years in the field - Now in 3rd generation design, but same small size
Variable speed simplicity - 2 speeds not required
7,000 ft-lbs torque - Higher than 2-7/8" IF thread rating
100-ton static load rating - 99 tons rotating load rating
Patented 10,000 psi Washpipe Seal Assembly, auto-lubricated - Much superior to any pressure energized seal design
Patented Power Tilt - Tilt angle quickly preset by driller - repeats throughout job. Automatically holds vertical when tilt not in use. Local control valve for safe loading/unloading is on power unit beside transport rack.
Patented Safety Valve - Prevents downtime if someone forgets to hook up the drain hose.
Four total hydraulic hoses on one powered hose reel
Optional Brake - Higher torque capacity than swivel output
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 7,500 psi for 1,000 hours. Lab testing is not field testing, and after two years in the field, reports are at 500 hours seal life. Later generation parts are already in the field, and two more improvements are about ready. When life data is available, we expect more than 1,000 hours of life before seal replacement.
The XK power swivels include our patented power tilt function. Our customers are very pleased with the safety benefits and time savings. The driller presets the max tilt angle to match the V-door angle at rigup, then the tilt always stops at the same angle during operation. When tilt is not required, the power swivel is hydraulically held in the vertical position without rope or chain. Only four hydraulic hoses are required, all on one hose reel.

XK-100 Power Units
Trailer Power Units
Two-axle trailers are arranged with rugged fender tanks for best road balance and serviceability. Units have electric brakes on both axles. gooseneck or bumper hitches are optional, and spare tire is included. Hydraulic-powered 4-hose reel is standard with 100 foot hydraulic hoses, and reel will accept 200 feet if required. The unit also includes a variable displacement piston-type hydraulic pump to allow any swivel speed desired. Caterpillar engines are standard, others are available.
Skid Power Units
Rugged oilfield skids are designed for truck winching and are fully floored. Heavy-duty dual tank design uses minimum floor space, and all equipment is arranged to allow easiest access for service. Hydraulic-powered 4-hose reel is standard with 100 foot hydraulic hoses, and reel will accept 200 feet if required. The unit also includes a variable displacement piston-type hydraulic pump to allow any swivel speed desired. Overhead lifting frames are available for offshore crane lifting. Caterpillar engines are standard, others are available.
Air Remote Controls
Air remote controls are connected by a 50-foot control hose umbilical. Controls feature stainless liquid-filled torque gauge, single handle control for direction/speed, auto engine throttle, and power tilt. Also included are engine kill (fuel shutoff), emergency engine kill (air shutoff), plus fool-proof torque release control which allows controllable unwind of the drill string before picking up. Emergency engine kill may also be locally operated at the engine.
A control box for setting maximum torque is mounted on each unit near the pump. Torque setting instructions are permanently marked on front panel of the box.
