Features& Advantages
1. Leak-proof capability: Static facial compensation technology effectively prevents the leakage of liquids or gases. Compared to traditional packing seals, our product has a lower leakage rate and provides more reliable sealing performance.
2. Wear resistance: The solid sealing structure reduces deformation under high and low temperature conditions and uses wear-resistant materials to extend the service life of the equipment.
3. Strong adaptability: High-speed limitation, up to 220 degrees. No sealing surface drop or displacement; pressure limitation, up to 25 bar.
4. Energy-saving and environmentally friendly: Reducing the risk of leakage, reducing energy waste, and minimizing environmental pollution.
5. Easy installation and maintenance: Only regular lubrication and replacement of seals are required. Suitable for API Plan 11/21/32/62 to reduce downtime and improve productivity. Easy to install and maintain.
