Grundfos mechanical seal provider 2022? When you are under pressure your concentration will be affected and most of the time the results will not be pleasing. The higher the pressure the lower the results of whatever works you are supposed to do. The same rule applies even to the shaft seals; when the fluid that is to be sealed is pumped with the pressure the seal lip will be directly affected. The expected high pressure in the seal lip will lead to a reduction of the rotational speed and the velocity in the circumference. The reduced speed means that the friction might be too high that can cause wear and tear to the shaft seal. Metric shaft seals will integrate the shortened seal lip that will reduce both the pressure and flexibility in the contact zones. The reduction of the rotational speed caused by these high pressures also leads to over temperature, and as a result, the seal experiences lack lubrication that is needed for its operations.

Lepu Seal grundfos mechanical seal manufacturers takes customers’ needs and real conditions into the serious consideration. Different types of materials including carbon, SIC, ceramic, high-density silicone are well chosen for manufacturing the sealing face. Before delivering, the product will be tested for several times and is guaranteed to have a long lifespan. Grundfos mechanical seal is one of the hottest products in Lepu Seal. We adopt the parts from Grundfos, the world’s largest pump manufacturer to ensure the quality of the seals. Find extra info on mechanical seals supplier.

The flygt pump seal is designed with the upper seal and lower seal. By using the Tunsten carbide, Tungsten carbide, and viton, the upper and the lower of the seal can be fitted smoothly, which ensures low leakage rates. When being operated in a controlled environment, the upper seal offers very high resistance. As for the lower seal, it features sturdy design and should be able to cope with fibrous clogging matter, hard abrasive particles, and chemically aggressive media, etc. The product is designed to accommodate short shaft overhang. Torque locks and drivers are independent of the shaft rotation and pump pressure acts as a closing force on the seal. What’s more, the frame of this Flygt mechanical seal is made of aluminum shell instead of old plastic frame, making the seal stronger and helping to against rusty problem.

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. Find extra details on China mechanical seals.

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.
