The water treatment process begins when raw water enters the media filter vessel. As the water flows through the predetermined layers of filter media, larger particles are captured at the top layer, while finer particles are trapped deeper within the media. This multi-layer filtration method ensures a higher degree of efficiency in removing contaminants. Over time, however, the media can become clogged with trapped particles, necessitating routine backwashing—a process in which water is pumped in the reverse direction to clean the media and restore its filtering capacity.

Sometimes, two different kinds of fluids leak from one chamber to another and gets mixed up. Here, this type comes as a boon. This is a metal inserted duplex type oil seal recommended on such assembly where mix-up of two different fluids is to be prevented.

For many bearings, a good bearing seal is essential. Bearing seals perform a dual function by keeping lubricants from leaking out while preventing impurities from entering your parts. Both procedures can help your bearings last longer, but choosing the proper seals for your components is critical. Different types of bearing seals include:
