Flygt pump seals manufacturer and supplier by lepuseal.com? Here in Lepu john crane mechanical seal suppliers and john crane mechanical seals distributors, we are available in the widest array of materials options including high-performance silicone carbides. Until now, we have several types of products including type 1, 2, 21, and 502. Each of them plays a unique role in different industries. For example, John Crane type 1 is normally used by the pulp, paper making, petrochemical, food processing, waste water treatment, and chemical processing industries. John crane type 502 is popular in the industries of pump, mixer, blender, agitator, air compressor, blower, fan, and other rotary shaft equipment. See even more info at flygt mechanical seals.
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.
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.

We adopt stainless steel as the raw materials to manufacture the frame and face of the seal, which makes the product be of rust protection, high impact resistance, and long service life. With strong technology – computational Fluid Dynamics (CFD), we establish exact geometry and make sure the whole production process conforms to the original production standard of the Alfa Laval. The working principle of this product is to form the thin liquid film between rotating ring and shaft, so that it can efficiently prevent leakage of medium and make the end face lubricated, which help achieve the sealing effect.
The temperature always has a part in everything you do, for instance, a change in temperature can make you change your plans anytime anywhere. The same changes in temperature are somehow unavoidable in shaft seals, whether it is hot or cold; there is an influence to the shaft seals that can later be related to its lifespan. When the temperatures are very high the seal materials will experience negative changes in its mechanical features that would, in turn, affect the durability of the seals. Extreme temperatures can lead to the unexpected malfunction of the seal while at the same time the seal lip will be harder than normal and cracks will also be noticed in the point of contact. The high temperatures can be as a result of environmental factors and friction that is normally caused by the seal lip during its operations. The resultant of high temperature caused by friction is normally known as the ‘over temperature’ since the seal gap temperature is higher than the oil bath temperature.
