Top rated mechanical seal manufacturer and supplier 2022? 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. See more details at mechanical seal manufacturer.
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.
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’ve absorbed plenty of experienced technicians, which guarantees that there is no sticking or clogging, making the design rugged and reliable. The seal is independent of direction of rotation, which provides more convenience for the movement of the product. It also has precise operating parameters including less than 0.5MPa operating pressure and wide temperature ranging from -20? to 120?. Compared with other series of seals, it has reliable sealing performance, small leakage, long service life, and low maintenance frequency. Thanks to its stable chemical performance, the product can stay perfect for more than one and a half years or even longer in the oil and water, or all kinds of corrosive acid, alkali, salt. Besides that, the shaft or bushing won’t get worn easily. One thing that needs to be mentioned is that this kind of products has good vibration resistance and will not be easily affected by the vibration and yaw of the rotating shaft.
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. Read extra details on lepuseal.com.
