Tungsten carbide sealing rings are divided into static and dynamic rings, which cooperate with each other to form a stable sealing structure. Tungsten carbide static ring can provide a strong and smooth contact surface.


Tungsten carbide static ring is a high-performance mechanical sealing element, which is mainly used in various pumps, compressors and mixing equipment, and is suitable for harsh working environments.


Langsun Carbide offers tungsten carbide sealing rings with the following characteristics:

Hardness and wear resistance

Tungsten carbide sealing rings have very high hardness (typically above HV1200) and can effectively resist wear.

Corrosion resistance

Strong corrosion resistance, able to maintain good performance in acidic, alkaline and other corrosive media.

Thermal stability

Tungsten carbide static ring can still maintain stable performance under high temperature environment, without thermal deformation or expansion, so as to ensure the sealing effect.

Mechanical strength

Tungsten carbide static ring has excellent mechanical strength, can withstand high pressure and high stress conditions, not easy to fracture or deformation.


Product application

Tungsten carbide static rings are widely used in the following fields:

  • Pump equipment: including centrifugal pumps, gear pumps, screw pumps, etc., used in petrochemical, pharmaceutical, food processing and other industries.

  • Compressor: applicable to various industrial compressors to ensure the sealing performance under high pressure conditions.

  • Mixing equipment: used for mixing equipment in chemical, pharmaceutical and other industries, to ensure the sealing effect of the equipment in complex media.


What are the advantages of choosing our products?

  • Long service life: due to its high hardness and wear resistance, the service life of tungsten carbide sealing ring is more than several times that of traditional materials.

  • Low Maintenance Costs: Reduced replacement frequency and maintenance time reduces the overall operating costs of the equipment.

  • High performance: In high temperature, high pressure and highly corrosive environments, it can still maintain good working performance, which improves the operating efficiency of the equipment.


We provide various specifications and sizes of tungsten carbide static rings, which can be manufactured with dynamic rings and can be customized according to customers' special needs. All products undergo strict quality testing to ensure that each product meets the high standard requirements. Please contact our sales team for more information and quotation.
