Cartridge type mechanical seal supplier 2023

Top rated cartridge type mechanical seal provider: Pressure Set: Presumably, the most well-known reason for O-ring disappointment is the pressure set. A compelling O-ring seal requires a consistent “seal line” between the fixed surfaces. The foundation of this “seal line” is an element of organ structure and seal cross-segment which decides the right measure of crush (pressure) on the O-ring to keep up seal trustworthiness without inordinate distortion of the seal component. There are various variables that can add to pressure set disappointment of an O-ring seal. Read even more info on

As a professional mechanical seal manufacturer, Lepu seal focus on mechanical seal manufacturing since 1998, viking mechanical seal is one of the main items which are popular in guangzhou local market. We provide new cartridge mechancial seal to replace the viking pump seal, and help our users to save lots of money, as everyone konw, original viking pump mechanical seal is very expensive, and the other problem is if you want to order that seal, sometimes you have to wait long time, but many factories can’t wait that long time. so chose lepuseal’s replacement is a good choice for many factories who using viking pump.

Lepu Seal provides Blackmer pump seal for its being used in the clean, non-corrosive industrial liquids and petroleum products. The typical applications include fuel oils, lube oils, jet fuels, gasoline, and edible oils industries. We carefully select high-quality SSIC as the raw material for stationing and rotating the seal face. According to scientific theory, the silicon carbide can stay stable under the high temperature of over 1400C and have excellent dimensional stability above 400 GPa. Under the chemical environment, silicon carbide helps the product resist the corrosion and erosion and improves its ability to withstand friction and wear. The product has a cartridge seal designed frame which allows it to be installed and maintained easily.

Mechanical seals are usually made by moving rings, stationary rings, compression elements and sealing elements. The operating principle is that the movable ring rotates together with the pump shaft, and the movable ring and the static ring are tightly bonded to form a sealing surface to avoid leakage of the medium. Considering the actual situation that mechanical seal running with other components of the pump together, Lepu Seal will perform strict tests for ensuring the function and technical requirements of the mechanical seals so that they can play an effective role in maximizing the value. They can be used in many applications. For example, our mechanical seals can be widely used in the field of chemistry, the oil and gas industry, the pulp and paper industry and the marine industry. What’s more, in the petrochemical and pharmaceutical industries, customers also can find the usage of our mechanical seals.

LEPU SEAL(China mechanical seal manufacturers) provides a wide range of Mechanical Seal for customers. Mechanical Seal is in line with stringent quality standards. The price is more favorable than other products in the industry and the cost performance is relatively high. LEPU SEAL insists on the principle to be honest, practical, and efficient. We continue to accumulate experience and improve service quality, so as to win praise from customers. We supply high-quality Mechanical seal, Grundfos mechanical seal, Burgmann mechanical seal, Cartridge Seal, Bellows Seal,etc.

For better satisfying the needs of customers, the product can be provided with different shaft sizes ranging from 24mm to 100mm. 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. Read more details on

The following aspects are going to affect the durability of your shaft seals. The aspect of the lubricant that is utilized. A lubricant in simple terms is a fluid that is supposed to soften a surface area that is rough. It is quite surprising to find out that it is one of the factors that will reduce the life span of your shaft seals. One fact that is known is that the interaction between the seal material and the lubricant is unavoidable; they must work together for good operations of the shaft seal. During the shaft seals operations, both the seal edge and the lubricant are highly visible to the unbearable thermal and mechanical conditions. The exposure is not quite good for your shaft seal since it makes them do more of the work than it is supposed to do. The exposure also allows for the clipping of the lubricating film and passing of oxygen which is otherwise not needed during operations.

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.
