Select from our engineering machinery and integrated high-pressure fluid systems for global deployment.
In modern structural geological exploration and deep foundation infrastructure, the seamless transfer of pressurized fluids (air, water, mud, or chemical slurry) from a stationary source into a continuously rotating drill string is a key mechanical challenge. The critical interface that makes this possible is the rotary swivel. Swivels must function under extreme physical conditions, balancing three primary forces: extreme rotational speed, high hydraulic or pneumatic pressures, and immense axial loads.
As a leading global heavy engineering designer and piling machinery specialist, SINOVO Group is at the forefront of providing custom ODM Swivel and complete drilling solutions. These components are vital for large-scale operations, including deep water wells, geothermal drilling, micro-piling, jet-grouting, and underground diaphragm wall construction. Standard components often fail under complex geological stresses; therefore, custom ODM designs that use special metallurgy, advanced face seal technologies, and high-tensile bearings are essential.
Global deep infrastructure requires higher flow rates and higher pressures. Customized swivels are essential for handling mud circulation and polymer additives without abrasive wear.
Using diamond-like carbon (DLC) coatings and double-acting polyurethane lip seals enables continuous rotation at up to 120 RPM under 400 Bar fluid pressure.
Every SINOVO heavy-duty swivel product undergoes rigorous testing for seal lifecycle, pressure containment, and anti-torque fatigue resistance.

| Axial Thrust Load Capacity | Under 50 kN | 50 - 200 kN | Over 600 kN (Self-lubricating roller bearings) |
We use a specialized dual-flow configuration that keeps high-pressure fluids separated from the lubrication chambers. This prevents mud contamination in the main bearings, reducing downtime.
The main spindle is forged from 42CrMo alloy steel, which is heat-treated to resist high torsional stresses and impact loads during tough drilling conditions.
The bolt-on design allows for easy maintenance of the packing seals and washpipes directly on the rig without removing the entire swivel assembly, reducing service times.
