shaft dust seal
In addition to preventing oil leakage, cylinder oil seals also help to prevent contamination. Contaminants such as dirt, dust, and moisture can enter the cylinder and cause damage to the internal components. This can lead to reduced efficiency, increased maintenance costs, and a shorter lifespan for the machinery. By creating a tight seal around the cylinder shaft, oil seals help to keep contaminants out and protect the internal components from 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.
