We use carbon and SIC as the raw materials for manufacturing the rotary and stationary seal parts. Due to the characteristics of the SIC, the product is endowed with the performance of stable chemical properties, low thermal expansion coefficient and good wear resistance. Besides that, the product is equipped with strong cast iron which gives it long service life. As for the secondary seal, we use EPDM to help the product gain the advantages of weather resistance, ozone resistance, heat resistance, acid and alkali resistance.
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.
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 information at https://www.lepuseal.com/.
John Crane mechanical seal is one of the most popular in the seals industry. Designed with a drive band and drive notches, this type of mechanical seal has a strong ability to absorb the force of the running torque. Its bi-directional and robust force of the seal face helps eliminate the pressure on the bellow. Its innovative bellows design is pressure-supported and will not crease or fold under high pressure. Besides that, the full convolution elastomeric bellows seal is designed to fit into confined spaces. Equipped with the function of automatic adjustment, it can be tolerant of the abnormal shaft-end play and run-out. There will be no clogging when this product is used and the single-coil spring keeps seal faces closed and properly tracking during all phases of operation. Under upset conditions, the positive drive through interlocking tangs will not go wrong.
