Oil seals are generally constructed from materials that can withstand the specific chemical properties of the lubricant they are sealing. Common materials include rubber, silicone, and various elastomers. The design of an oil seal often incorporates a lip that rolls against a shaft or surface, creating a dynamic seal that can accommodate movement while maintaining its sealing capabilities.

hub seal. This is crucial for maintaining the efficiency and reliability of machines, as excessive friction can lead to overheating, increased energy consumption, and premature wear. By effectively sealing the interface between two surfaces, hub seals enable smooth operation and optimal performance.
The design of the volute is crucial for the efficiency of the pump. A well-designed volute minimizes flow separation and turbulence, ensuring a smooth transition of the fluid from the impeller to the discharge pipe. The volute shape is typically spiral, which facilitates a uniform flow distribution. If the volute is improperly designed, it can lead to inefficiencies such as cavitation, vibrations, and noise, significantly affecting the pump's overall performance.
