Top mechanical seal manufacturer right now? 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.
We 100% follow original and exquisite seal design concept to make sure the perfect performance applied in the machines. Our grundfos pump seals have passed various certifications like ISO, SGS, and CE. Precise and advanced machines are purchased for ensuring the width, height, thickness, and diameters of each part, or it may cause mechanical breakdown to a certain extent. Stainless steel is the main material adopted for the sealing frame, sealing joints, and so on, which is for the rust resistance and corrosion resistance of the product. The product can be easily installed in the machines and offers high resistance when working. Besides that, it has the excellent performance of high and low temperature resistance, so it can stay stable under the working temperature from -30C to 200C.

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.
Lepu Seal always puts quality the first. During the production process, we are detail-oriented to each step. Advanced production technology is utilized and carried out for the manufacturing of the product, which makes it perfectly prevent the fluid and solid particles from leaking into the machine. In addition, exquisite workmanship guarantees the high quality. It is characterized by its durability, reliability, and ageing resistance.
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 additional details at China mechanical seals.
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.
