The mechanical seal is one of the most critical components in a hygienic rotary lobe pump. It prevents product leakage while maintaining reliable and hygienic operation. Like any wear component, the mechanical seal should be inspected regularly and replaced when necessary to ensure optimal pump performance.

Why Replace a Mechanical Seal?

Mechanical seals may require replacement due to:

• -Normal wear after long-term operation
• -Product leakage around the shaft
• -Seal face damage
• -Preventive maintenance during scheduled service

Timely replacement helps reduce unexpected downtime and extends the service life of the pump.

Basic Replacement Procedure

The general replacement process includes:

1. -Remove the pump cover and rotors.
2. -Carefully disassemble the existing mechanical seal.
3. -Clean the seal housing and shaft thoroughly.
4. -Install the new mechanical seal according to the manufacturer's specifications.
5. -Reassemble the pump and verify the rotor clearance.
6. -Perform a leak test before returning the pump to operation.

Important Notes

• -Handle seal faces carefully to avoid scratches or impact damage.
• -Ensure all sealing surfaces are clean before assembly.
• -Replace O-rings if signs of wear or deformation are found.
• -Verify the correct installation direction of all seal components.
• -Always perform a functional and leak test after maintenance.
