Mechanical seal model 109 20 alloy fluororubber shaft diameter zero point seven nine inch outer diameter one point three eight inch

Product Introduction Brand: JIMING Product Name: 109 Series Mechanical Seal Model: 109-20 Alloy-Fluororubber Shaft Diameter: 0.79in (20mm) Shaft/Sleeve Outer Diameter: 1.38in (35mm) Quantity: 1 Piece Application: Pumps, Compressors, Reactors in Chemical, Petroleum, Paper, Food Industries Product Features Constructed from alloy and fluororubber, this mechanical seal offers excellent resistance to wear, corrosion, and chemical exposure, making it suitable for harsh industrial environments involving diverse fluids and chemicals. It operates efficiently within a temperature range of -30~200°C, enabling use in both low-temperature and high-temperature applications, such as cryogenic processing or hot fluid handling. With a maximum pressure tolerance of 1.2MPa, it maintains a reliable seal in medium-pressure industrial processes, preventing fluid leakage and ensuring operational safety and efficiency. The precise shaft diameter (0.79in/20mm) and shaft/sleeve outer diameter (1.38in/35mm) ensure accurate compatibility with a wide range of industrial pumps, compressors, and rotating equipment. Supporting a line speed of up to 10m/s, it is well-suited for standard rotating shafts commonly found in industrial machinery, providing stable performance without excessive wear. As a widely applied mechanical seal in industries like chemical, petroleum, paper, and food, it serves as a reliable solution for preventing fluid leakage in pumps, compressors, reactors, and other critical equipment. Usage Instructions Ensure the equipment is shut down and isolated from power sources before starting the installation process. Remove any existing seal and thoroughly clean the shaft, sleeve, and seal cavity to remove debris, residue, or old sealing material. Inspect the new JIMING 109 mechanical seal for any damage or defects. Verify that the shaft diameter (0.79in/20mm) and shaft/sleeve outer diameter (1.38in/35mm) match your equipment’s specifications. Install the seal according to the equipment manufacturer’s guidelines, ensuring proper alignment and seating to maintain sealing integrity. Pay attention to the correct orientation of the seal components. Reassemble the equipment and conduct a leak test under low pressure initially. Gradually increase the pressure and monitor for any signs of leakage or abnormal operation. Perform periodic inspections during routine maintenance to check for wear, damage, or leakage. Replace the seal promptly if any issues are detected to avoid equipment damage or operational failures.
