Developed by Forever Seals, the HSPGL series seals reduce leakage risks for light hydrocarbon/volatile media pumps, ensuring stable operation in demanding scenarios. Their dual-sealing design boosts safety and cuts maintenance, meeting industrial pumping systems’ long-term efficiency needs. With a 2-3 year service life, they also offer a cost-effective, low-fuss sealing option.
Forever Seals offers top - notch mechanical seals, including the HSPMR series. These seals, with multi - spring design, ensure reliable sealing performance across various industrial applications. They meet strict standards and are suitable for diverse media in sectors like chemical and petrochemical industries.
Forever Seals' HSPGD series double - end face dry gas seal ensures "zero leakage" or "zero overflow" of process media. It has a power consumption of less than 10% of contact seals and a service life of over 3 years, suitable for pumps transporting toxic and liquefied gas media.
The HSPCT series mechanical seal is a series - connected contact seal. It is ideal for flammable, explosive and toxic chemical fluids, featuring a multi - spring, lug drive and balanced structure. With a lifespan of 2 - 3 years, it requires a buffer fluid auxiliary system during use.
The HSPBT series mechanical seals are series - type bellows seals. They are suitable for the PLAN55 system, allowing a small amount of buffer fluid to enter the process medium. With features like non - contact operation, low power consumption, and long service life, they can be used for sealing pumps handling high - temperature and multiphase media.
The HSPBS - 1 Bellows Mechanical Seal is a high - performance sealing device from Forever Seals. It adheres to API 682 and JB 8723 standards, featuring configurations like single/double - end face sealing and cartridge/non - cartridge types. Capable of withstanding a broad range of pressures, speeds, and temperatures, and suitable for various media, this seal ensures efficient and leak - free operation in numerous industrial applications.
The HSPBS Series Bellows Mechanical Seals from HISCIEN meet API682 and JB8723 standards. They offer single/double - end face sealing, cartridge/non - cartridge options, and are suitable for a wide range of pressures (0 - 6.9 MPa), linear speeds (≤50 m/s), temperatures (-75 ~ 425 °C), and media like hydrocarbons and high - temperature viscous substances. These seals ensure reliable performance in diverse industrial applications.
These high - performance transmission oil rings are essential sealing components. They effectively prevent transmission oil leakage, ensuring that all internal parts of the transmission operate smoothly in a proper oil environment. With their reliable performance, they play a crucial role in enhancing the transmission system's efficiency and extending its service life.
SPGA seals are high - quality and durable sealing solutions. They are specifically designed for hydraulic cylinder applications, ensuring reliable sealing performance in various working conditions. With excellent sealing ability, they help enhance the efficiency and longevity of hydraulic systems.
This rubber diaphragm, crafted from premium materials like nitrile rubber or fluororubber, serves as a vital sealing and pressure - transmitting component. It ensures reliable sealing, efficient pressure transfer, and effective medium isolation in hydraulic, pneumatic, and automotive systems.
These are butterfly valve sealing rings, designed for food and sanitary pipeline systems. They ensure excellent sealing performance at the butterfly valve connections, preventing fluid leakage and maintaining the tightness of the pipeline during medium transportation.
These high - quality valve rubber seals are premium sealing components for petroleum equipment. Made of durable polyurethane, they offer excellent oil resistance, corrosion resistance, and wear resistance, ensuring reliable performance in various oilfield operations.
