Take the mechanical seals - the most commonly used and popular products now - as the example:
It is also known as a face seal, which is a rotary machine shaft seal device that can avoid the leakage of the fluid. It is widely used for the rotation of the shaft seal, for pumps, kettle, compressor, and other similar equipment. There are a lot of materials for manufacturing the mechanical seals, including rubber, stainless steel, PTFE, carbon, ceramic, Sic and TC.
Mechanical seals are usually made by moving rings, stationary rings, compression elements and sealing elements. The operating principle is that the movable ring rotates together with the pump shaft, and the movable ring and the static ring are tightly bonded to form a sealing surface to avoid leakage of the medium. Considering the actual situation that mechanical seal running with other components of the pump together, Lepu Seal will perform strict tests for ensuring the function and technical requirements of the mechanical seals so that they can play an effective role in maximizing the value. They can be used in many applications. For example, our mechanical seals can be widely used in the field of chemistry, the oil and gas industry, the pulp and paper industry and the marine industry.
