M37G series mechanical seal model M37G 48 alloy nitrile rubber shaft sleeve outer diameter one point eight nine inch

Product Introduction Brand: MECAN Product Name: M37G Series Mechanical Seal Model: M37G-48 Material: Alloy-Alloy-Nitrile Rubber Shaft/Sleeve Outer Diameter: 1.89in (48mm) Quantity: 1 Set Application: Clean Water Pumps, Sewage Pumps, Submersible Pumps, Chemical Pumps Product Features Constructed from alloy and nitrile rubber, this mechanical seal provides superior resistance to wear, corrosion, and operates efficiently within a temperature range of -20~180°C, making it suitable for diverse operating conditions. With a precise 1.89in (48mm) shaft/sleeve outer diameter, it fits accurately into compatible equipment, guaranteeing optimal sealing performance. It is a large spring component seal of non-balanced type, complying with DIN24960 standards. The moving ring features a carbonized silicon structure, and the static ring is graphite with a conical spring, ensuring easy installation, wide application, and high reliability. With a maximum pressure tolerance of 1.0MPa, it maintains a reliable seal in relevant pressure processes, preventing fluid leakage and ensuring operational efficiency and safety. Its versatile design makes it ideal for a range of pumps including clean water pumps, sewage pumps, submersible pumps, and chemical pumps, providing flexibility across different applications. As a comprehensive set, it includes all components needed for a complete seal replacement, eliminating the need for separate part sourcing and ensuring compatibility. Usage Instructions Ensure the equipment is shut down and isolated from all power sources before starting the installation process. Remove the existing seal (if present) and thoroughly clean the shaft, sleeve, and seal cavity to remove any debris, residue, or old sealing material. Inspect the new MECAN M37G series mechanical seal set for any visible damage or defects. Verify that the shaft/sleeve outer diameter (1.89in/48mm) matches your equipment’s specifications. Install the seal according to the manufacturer’s guidelines, ensuring proper alignment and seating. Pay close attention to the correct orientation of all seal components, especially the conical spring and carbonized silicon moving ring, to maintain sealing integrity. Reassemble the equipment and conduct a leak test under low pressure initially. Gradually increase the pressure and monitor the seal for any signs of leakage or abnormal operation. Perform regular inspections during routine maintenance to check for wear, damage, or leakage. Replace the seal set promptly if any issues are detected to avoid equipment damage or operational failures.
