Mechanical Seals

A mechanical seal is a device made to seal the passage point between two parts and join them together. Mechanical seals are essential for rotating equipment like pumps, compressors, and other rotating shafts.

It is essential to have proper maintenance of equipment and its seals. If the seals are poorly maintained, it can lead to leakage that can cause significant breakdown and downtime and injure the employees.

So here are some of the tips for maintenance and extending the lifetime of your Mechanical Seals:

Top 4 Tips for Maintenance of Mechanical Seals

  1. Lubrication of Seals is Perfect

Lubrication is an essential requirement of mechanical seals to function well with the rotating shafts and pumps. If there is no fluid layer between seal faces to reduce the friction and cool them down, then the heat will build-up, resulting in dry runs that will result in high friction, increased temperature, and extra wear and tear of the seal.

To ensure that your Mechanical seals won’t run dry, you can install Dry Run Monitor that provides the alarm settings, which will alert or notify the employees or person in charge when there is insufficient lubrication. This scenario will keep your mechanical seals fully operational efficiently.

  1. Check for Excessive Vibration

Excessive vibration is an indication of the pump not operating within its BEP(Best Efficiency Point); this can cause recirculation and cavitation, which leads to vibration transferring from the impeller to shafts and then to the mechanical seals. This vibration can lead to higher friction and degradation of the Mechanical seal face.Check for the misalignment of couplings or suctions.

  1. Proper Installation

Following proper installation procedures like plate and shaft alignment, number and location of the fastener, its torque level, adequate venting and port connection, etc., can improve the lifespan of the Mechanical seal and the whole system. The wrong installation can lead to excessive wear and tear of the seal and machinery during operation. Therefore, it’s necessary to have seals appropriately installed, well-aligned, and 100% geometric.

  1. Lookout for Pump specifications

Suppose the pumps are not operating according to the manufacturer’s specification and its alignment, torque level, or other essential factors are not matched. In that case, the mechanical seal will be the part that absorbs extra force, which reduces the seal’s lifespan immensely.

Key Takeaways

So, it is crucial to have precise equipment maintenance and sustenance of its seals. We hope these recommendations for maintenance and extending the lifetime of your Mechanical Seals will be helpful to you.
