Besides that, being made of high-quality stainless steel and welded by the advanced machine, the product has no burr on its surface and gives people a strong feeling of smoothness. To ensure its superior performance, the product will be tested thousands of times for its high load resistance, good self-lubricating effect, good wear resistance, and good resistance to thermal cracking. Thanks to the small coefficient of liner expansion of the materials, the product can resist heat deformation and enjoy dimensional stability. It has high size precision, which perfectly matches the dimensions of the Nissin Pump.

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.

Increased high temperatures also lead to fast corrosion of the medium to be sealed and may also have a negative effect on the extracts that lead to unwanted reactions which cause damages to the seal materials point of contacts. For the metric shaft seals, the story is different because their materials are suitable for any temperature and are oil resistance. They have also been fitted with friction optimized seals that help reduce the heat produced during friction and curb the issue of over temperature in the seal lip. There are other factors that normally affect the lifespan of your shaft seal but the ones mentioned above are most vital and you should take a keen interest in them. You can also put your focus on the metric shaft seals that are well designed to curb the above factors and allow for a longer durability feature.
