Once the larger particles are removed, the water undergoes sedimentation, where it is allowed to sit in large basins. During this time, heavier particles settle to the bottom, forming sludge that can be removed. The next step is often filtration, which can involve layers of sand, gravel, and activated carbon to further eliminate finer particles and chemical contaminants.

Custom-made rubber oil seal

The basic principle of an oil seal is fairly straightforward. It is installed adjacent to the bearing, with the flexible lip against the rotating shaft and the casing pressed into the housing to hold the seal in place. It’s important that the sealing lip is lubricated to prevent it from overheating as a result of any generated friction. It’s also crucial to understand which type of seal is appropriate for your particular machinery. Before selecting your seal, consider the environment, temperature, pressure and shaft speed of your machine, as well as the type of medium the seal will come into contact with during operation. These considerations will all determine the size, colour, and type of lip material or sealing element to choose, and whether it can be sealed in or sealed out.
