In addition to material, oil seals are also categorized based on their design and construction. The most common types include lip seals, mechanical seals, and hydraulic seals, each designed for specific applications and conditions. Lip seals are the most basic type and consist of a flexible lip that contacts the shaft to prevent leakage. Mechanical seals, on the other hand, utilize a rotary or stationary face to create a seal, while hydraulic seals are used in hydraulic systems to prevent fluid from leaking

Proper installation and maintenance of oil seals are crucial for ensuring their effectiveness and longevity. Seals should be installed with the correct orientation and alignment to prevent premature wear and leakage. Regular inspection and replacement of seals are also important to prevent costly downtime and damage to machinery.
However, when a hub axle seal fails, the consequences can be dire. Leaked lubricant can lead to bearing failure, increased friction, and ultimately, costly repairs. More subtly, a compromised seal can allow corrosion to take hold, silently eroding the integrity of the axle from within. Thus, the lowly hub axle seal not only ensures the efficient function of the drivetrain but also protects against potentially catastrophic damage Thus, the lowly hub axle seal not only ensures the efficient function of the drivetrain but also protects against potentially catastrophic damage

There are several types of impellers used in sewage pumps, each with distinct features catering to various types of sewage applications. The most common types include open, semi-open, and enclosed impellers. Open impellers have no front shroud, allowing for larger solids to pass through without clogging. This makes them ideal for handling raw sewage containing debris. Semi-open and enclosed impellers, on the other hand, are more suitable for cleaner liquids, offering better efficiency and pressure generation.
