Cartridge mechanical seal provider today


Excellent grundfos pump seal provider: Scraped area: Another somewhat basic sort of O-ring disappointment is the scraped area. This generally is discovered just in unique seals subject either to reacting to, wavering, or turning movement. Distinguishing proof of abrasion failure: O ring seal that has bombed because of wear through the scraped spot, as a rule, displays a level territory in favor of the seal that was in contact with the dynamic surface. As often as possible there will be wear lines on this level surface are parallel to the heading of movement. Find even more details 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.

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.

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.

We are mainly engaged in the production of the mechanical seal. LEPU SEAL’s mechanical seal series contains multiple sub-products. LEPU SEAL has great production capability and excellent technology. We also have comprehensive production and quality inspection equipment. Mechanical seal has fine workmanship, high quality, reasonable price, good appearance, and great practicality. The following are the cooperative partners we have. Company profile: It is a leading and professional pump factory in the south of China. Lepu Seal has been providing seals for its pump products since 2003.

Lepu Seal’s aes mechanical seal is a perfect replacement for AES cartridge seal convertor. We have perfect designers who keep improving themselves and they can ensure 100% the same design as the original AES cartridge seal convertor. As an important cartridge seal convertor, this kind of product is designed with perfectly precise dimensions, width, length, and so on. It is designed to replace two-part component seals and conventional packing arrangements. It is a cartridge seal type with short external length. Its cartridge seal frame adopts high-quality stainless steel and the seal face is made of high-density silicon. All these materials are characterized by stable chemical properties and endow the product with chemical resistance like acid resistance. Read more info on

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.

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.
