The spring seal produced by DMS SEALS is perfect for being applied to extremely high-speed, very low-speed equipment with micro piston strokes and other special operating conditions. It can be used with rotary seals and maintains good sealing performance in violent shake and vibration motion environments. At the same time, our seals are extremely adaptable to a wide range of working media. It is resistant to a wide range of chemicals except for soluble alkali metals, high-temperature fluorine and chlorine trifluoride. Therefore, it works well with liquids such as oils and water with high and low temperature.

DMS SEALS’ s bonded seal is ideal for being applied to threaded pipe fittings and plug sealing in Metric, British and BSP systems. The seal has no special requirements for the positioning and processing techniques of the seal groove, so it is an ideal accessory for fast and automatic installation that we highly recommend. The operating temperature range is -30°C ~ 100°C, and the working pressure is less than 39.2 MPa. It is commonly used in a hydraulic oil medium.

Our piston seals are designed to provide excellent leak control. We guarantee that it can perfectly meet the user’s requirements for low friction, compactness, precise configuration and simple installation. It is designed for fluid power applications. It is made of compound materials with high performance, which guarantees excellent wear resistance and excellent extrusion resistance for the seal. It is designed to be suitable for almost all fluid media and is highly resistant to oxidation and corrosion. It has excellent dynamic and static sealing performance and can even work under dusty industrial environments. Moreover, it has strong adaptability to various working conditions and can adapt to a fast, high-pressure working environment. At the same time, it has unparalleled performance in extreme temperature environments.

Diffusion leakage: Driven by the concentration difference, the medium leaks through the material transfer generated by the sealing gap or the capillary of the sealing material. Diffusion is the result of molecular motion and is not unidirectional. When the sealing pressure difference is extremely small or in a vacuum state, or when sealing permeable substances such as nitrogen and hydrogen, as well as highly toxic and radioactive substances, special attention should be paid to the leakage and diffusion.

Due to the volume and weight limitations of the system, it is impossible to install an ideal filtration and cooling system. High temperature, high pressure, and high speed cause the hydraulic oil to deteriorate easily, and the mechanical parts are also prone to erosion and stains. There are many stains and impurities in hydraulic oil, but it cannot be thoroughly filtered, which is the aspect of endogenous stains. All kinds of dust in the working environment may be very large, and it will inevitably enter the hydraulic system in multiple ways, causing oil pollution, which is an external stain. Therefore, the sealing system is required to be resistant to stains.

We own a number of invention patents and leading production process. The R&D teams have the ability to design and develop seals for various of complicated working condition of sealing system. We have already passed the certification of ISO 9001 and IATF 16949. We have the mature technical reserve for the solution of ultra-high temperature, ultra-high pressure, ultra-low temperature, highly corrosive and other special working condition.
