Grundfos mechanical seal manufacturer and supplier 2022? 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.

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. Find extra information at mechanical seals supplier.

Lepu Seal’s Burgmann mechanical seal is balanced and can be arbitrarily twisted. It has PTFE bellows and its spring is protected by PTFE cover. Each part of the product is made according to the standard of German Burgmann. It is widely used for the seals on harsh conditions like high temperature, high pressure, and vacuum. Flygt mechanical seal is usually used in the Swedish ITT Flygt mixer and submersible sewage pumps. It is one of the essential mechanical seals for Flygt pumps. In Lepu Seal, we mainly supply Flygt replacement seals in strict accordance with the original size of the mold parts and original materials. The plug-in cartridge mechanical seal is one of the most popular products.

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.

We provide CAD drawings for customers so that they can see the inner parts and external design of the seals. Or if customers have their design concept or already get their product drawings, it is also practicable in Lepu Seal. Sample production and delivery: After getting confirmation from customers, Lepu Seal will make the exact sample based on the drawing. Having finished the sample, we will carry out strict QC procedure to test the sample and then deliver it. Discover extra information on mechanical seal factory.

For better satisfying the needs of customers, the product can be provided with different shaft sizes ranging from 24mm to 100mm. In Lepu Seal, Alfa Laval mechanical seal LPSRU3 is a professionally designed mechanical seal replacement for Alfa Laval pump SRU3. Super light screws are designed on the seal ring, which both guarantees the easy operation and strong structure. Each product is designed with precise dimension ranging from 20mm to 45mm, which can satisfy the different needs of customers.
