Hebei Hankai motor seal kit


This particular oil seal is designed to accommodate a shaft diameter of 50mm while sealing against a housing with an outer diameter of 90mm, ensuring tight closure and effective sealing. The 10mm width is optimal for creating a sufficient sealing surface to prevent leakage while maintaining a low profile in installations.

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.

Wet parts in a pump, including the impeller, casing, and liners, are continuously exposed to the fluid being pumped, making them prone to wear. Monitoring the condition of these wet parts is crucial for maintaining pump performance. Regular checks and the use of wear indicators can help you determine when a pump wet end replacement is necessary. By establishing a monitoring routine and setting clear wear thresholds, you can replace these components before they fail, thus avoiding unscheduled downtime and extending the overall lifespan of the pump.
