Excellent flygt mechanical seal provider right now? 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.

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 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 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 more info on 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.
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.
