The mechanical seal is a device used to prevent fluid leakage. The high temperature and high pressure mechanical seal produced by our company can be used to seal oil, water, weak base, weak acid, flammable, explosive, and toxic gases, propylene, toluene, potassium metal, acid, alkali, polymer suspension, etc. The working temperature is between -40℃ and 180℃, and the rotational speed is less than 2m/s.
Made of materials resisting high temperature and pressure, our product has excellent stiffness, strength and impact resistance. It has a small coefficient of friction and good self-lubricating properties. Even if a short period of interfacial friction occurs, the seal face will not be damaged. When using this product, a pressure balancing device is required. This can effectively ensure the safety and stability of the product.
As a specialized high temperature & high pressure mechanical seal manufacturer in China, Miyou Group provides a wide array of products, including bottom agitating mechanical seal, metallic nanometer powder, jet mill system, Air Classifier System, and more.
