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.
It can maintain stable performance after prolonged exposure to various corrosive compounds. Due to its lack of polarity, low unsaturation, and high chemical stability, our gasket has high resistance to various polar chemicals such as alcohols, acids (acetic acid, hydrochloric acid, etc.), strong base (sodium hydroxide, oxidant, hydrogen peroxide), detergents, animal and vegetable oils, ketones and certain esters. It is designed to have excellent aging resistance and excellent resistance to compression set and compression stress relaxation. Therefore, our gasket has significant advantages over other conventional gaskets. Its excellent materials and manufacturing process enables it to achieve effective sealing when exposed to corrosive chemicals, friction, high temperatures or very low temperatures. At the same time, it is easy to install and has industry-leading creep resistance, which saves users a lot of time and cost and increases productivity.
The rod seals can be operated with or without lubrication. We guarantee strong dimensional stability and a low coefficient of friction. Changes in temperature do not affect its performance. It is easy to install and can be used with piston rods with the larger diameter and heavy-duty hydraulic rod sealing systems to provide a tight and excellent seal. DMS Seals with 12+ years of experience for manufacturing rod seals, we are confident to provide top quality & satisfying product. There are hydraulic rod seals, piston rod seals, etc for selection, welcome to contact us for further details.
The selection principle of the gasket: according to the working pressure, working temperature, the corrosiveness of the sealing medium and the form of the sealing surface. Temperature influence: In normal temperature and low pressure, use non-metallic soft honey gasket; in medium pressure and high temperature, choose metal and non-metal combination gasket or metal gasket; when temperature and pressure fluctuate greatly, choose good elasticity or self-tightening type Gaskets; in low temperature, corrosive media or vacuum conditions, gaskets with special properties should be considered.
Good sealing performance: Because the system works outdoors, there is no leakage oil recovery system, and the working medium will directly pollute the environment after leakage, so external leakage requirements are strict. At the same time, for the requirements of hydraulic oil heating control, pressure maintaining or maintaining position, the internal leakage requirements are also very strict. High pressure: The working pressure of the hydraulic system is high, usually above 20MPa, and the highest is about 40Mpa, which is higher than the general industrial hydraulic system pressure, so the sealing pressure resistance requirements are high.
