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. 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. It has several unparalleled advantages compared with other types of mechanical seals. Firstly, it has a good sealing function, which means the sealing state is very stable, and the leakage is small even after a long working time. Secondly, it has the advantage of small consumption of friction power and the abrasion of the shaft or sleeve can be negligible.

We put customers the first and take customers' demand into serious consideration. Various types of materials are available for the product including carb, silicone, viton, NBR, and EPDM.
