1. Removing the Old Mechanical Seal

When replacing a mission pump’s mechanical seal, first remove the old seal. Before removing, ensure the mission pump is powered off and disconnected from the main power supply to ensure safe operation. Next, follow the steps below to disassemble:

1. Remove the pump body end cover screws symmetrically and gently remove the pump cover. Be careful not to damage the pump cover and screws during removal.

2. Completely remove the motor and impeller. For larger mission pumps, if the impeller is difficult to remove, use the screw holes in the pump cover to push it out. Be careful to avoid bumping or knocking the motor and impeller when removing them.

3. After removing the impeller, the dynamic and static rings of the mechanical seal will be visible. Use specialized tools to gently remove the dynamic and static rings. Be careful not to damage the sealing surfaces of the dynamic and static rings during removal.

4. Clean the removed mechanical seal components and inspect for damage or severe wear. Replace any components as needed.

2. Installing a New Mechanical Seal

After removing the old mechanical seal, you need to install a new one. Before installation, ensure the new mechanical seal components are ready and inspected for damage. Follow the steps below for installation:

1. Clean the pump shaft and stationary ring groove, ensuring they are clean and free of debris. Apply a generous amount of grease to the pump shaft and stationary ring groove to ensure smooth installation.

2. Install the new stationary ring into the stationary ring groove, ensuring it is flat and not tilted. Ensure the sealing surface of the stationary ring faces upward.

3. Apply grease to the inner ring and end face of the rotating ring, then secure it against the end face of the stationary ring. During this process, ensure that the rotating ring can extend and retract freely without any binding.

4. Slide the impeller onto the pump shaft, using a small wooden block to cushion the impeller. Gently tap with a hammer to secure the impeller in place. Then, tighten the impeller retaining screws to ensure they are secure and not loose.

5. Insert the motor and impeller into the pump body, taking care to avoid any bumps or friction during insertion. Adjust the impeller position to ensure smooth rotation without obstruction. Then, evenly tighten the end cap screws to complete the installation.

6. Start the mission pump for a test run to check that the new mechanical seal is correctly installed and leak-free. If any abnormalities are detected, immediately stop the machine for inspection and make adjustments.

With these steps, you can successfully complete the replacement of the garniture mécanique de la pompe à mission. During operation, please ensure that the environment is clean and tidy to prevent debris and dust from entering the seal area, which could affect the sealing effect. Regular inspection and maintenance of the mechanical seal is also important to ensure proper operation and extend its service life.
