PTFE Slide Seals Oil Pumps Sliding Elements
The slide seals used in oil pumps for vehicles, bus, tractor, etc, play a key role in preventing fluid leakage, maintaining pump chamber pressure, and improving volumetric
efficiency. By precisely fitting between the rotating shaft and housing, they create a dynamic sealing interface through medium pressure and sliding contact. It is usually made by carbon or PTFE sliding seals provide low friction and reliable zero-leakage performance under high pressure differentials, making them suitable for wide temperature ranges and high-speed rotating applications.
