Compressor Mechanical Seal Manufacturer
Sakowit designs and manufactures high-performance mechanical seals for industrial compressors. Our seals deliver leak-free performance, high efficiency, and long-term reliability across gas, oil, and process industries.
Understanding Compressor Mechanical Seals and Their Function
The mechanical seal of the compressor is a crucial component designed to prevent the leakage of gases or liquids. It is installed at the end of the rotating shaft of the compressor, forming a highly precise sealing interface between the moving ring and the stationary ring. As the shaft rotates, there is only a thin liquid film of 1–3 micrometers between the sealing end faces. This extremely thin lubricating film not only reduces friction but also prevents the leakage of process gases.
Compared with traditional packing seals or lip seals, mechanical seals can achieve a higher level of sealing. In industrial gas compression systems, their leakage rate can be controlled below 10⁻³ mbar·L/s, meeting the international sealing standards of API 682 e ISO 21049. This sealing method significantly enhances the operating efficiency, safety and service life of the compressor.
Why Reliable Mechanical Seals Are Critical for Compressors
The compressor operates under high pressure and high speed conditions. Any minor leakage could lead to loss of gas, decrease in efficiency or safety hazards. The mechanical seal achieves this through high-precision end face alignment, forming a very thin gas or liquid film between the moving and stationary rings, effectively preventing the medium from leaking along the shaft.
Compared to traditional packing seals, mechanical seals can achieve a more stable sealing effect. In industrial compression systems, their leakage can be reduced by more than 90%, the operating efficiency can be increased by approximately 5-10%, and the maintenance intervals of the equipment can be significantly extended (on average, by 40-60%).
Mechanical seals can also maintain the purity of the process gas, preventing cross-contamination between lubricating oil and gas, and ensuring the product quality and system safety in the chemical, petrochemical and pharmaceutical industries.

Sakowitz Engineering Solutions for High-Performance Compressor Mechanical Seals
Sakowitz specializes in the design of compressor seals under high-pressure, complex media, and high-speed rotating conditions. Our mechanical seals have undergone rigorous engineering calculations and on-site verification, and can maintain stable sealing performance under working pressures up to 80 bar and rotational speeds up to 60 m/s.
The sealing structure supports single-end, double-end e dry gas seal configurations. The moving and stationary rings are made of silicon carbide (SiC), carbon ou tungsten carbide, which can effectively resist wear, cavitation and thermal deformation, ensuring the stability of the end face under high-pressure gas compression and high-speed friction conditions.
The metal components are made of corrosion-resistant alloys such as Hastelloy®, Inconel®, SS316, etc. They can maintain strength and corrosion resistance even in harsh media containing hydrogen sulfide, chloride, or fluoride. All products comply with international standards such as API 682, ISO 21049, ASME, and have passed leak, pressure resistance and thermal cycling tests.
Sakowitz seal is widely applicable to centrifugal, screw and reciprocating compressors. It demonstrates outstanding stability and reliability in the petrochemical, natural gas, hydrogen, air separation and refrigeration industries.
