What are the two basic types of pump shaft seals?

The two basic types of pump shaft seals are compression packing and mechanical packing. Compression packing consists of a series of rings or strands of material that are installed around the shaft and compressed to create a seal. This type of seal can often be adjusted by tightening the packing gland, allowing for maintenance and longer service life.

Mechanical packing, on the other hand, is a more sophisticated form of sealing that typically utilizes a combination of a stationary and a rotating component which create a sealing interface. The design of mechanical seals allows them to effectively handle higher pressures and temperatures compared to compression packing. They can also reduce leakage significantly, making them more efficient for specialized applications.

Understanding these types of seals is crucial for an Ice Facility Operator because they play a key role in maintaining system integrity and efficiency, helping to prevent leaks, reduce maintenance requirements, and extend the lifespan of equipment.
