Elastomer Bellow Mechanical Seal Basics

Elastomer bellows mechanical seal is identified by the use of a unique elastomer bellows or diaphragm for the secondary sealing part, which provides a high degree of axial flexibility to compensate for lack of concentration of the shaft & misalignment & wear due to thrust movement of the shaft.

 

Elastomer bellow seal is the most commonly and generally used rubber bellow seal, due to its compact design, easy installation, mass production and low cost.

 

Elastomer seal is non-directional, technically advantageous and extremely versatile. Elastomer bellow mechanical seal can be used regardless of the direction of the rotation since the driving torque is not transmitted through the single coil spring. The required driving torque is enhanced through the rubber bellow which fits on the shaft through the interference fit between the collar, rubber bellow, and shaft.

 

So as to meet the varying demands of our overseas customers, we are involved in manufacturing and supplying a collection of high-quality rubber bellow seals with competitive price, no minimum quantity.

 

Because of its excellent performance in various industries, as well as it’s compact design, cheap price and variety, rubber bellow mechanical seals are the most commonly used industrial seals.

 

Shaft runout is compensated by Elastomer bellow and spring due to its self-aligning capability. Elastomer Bellow protects Shaft/Sleeve from Fretting.

 

Elastomer Bellow Metric Mechanical Pump Seals Application

Elastomer bellow seals are widely used in the centrifugal pump, water pumps, circulation pump, submersible pumps, auto cooling pumps, general industrial pumps and other rotating equipment, high-temperature applications of various chemical, petroleum, refinery and polymer industry.

 

Highly recommended application

 

water transfer applications

 

Sewage applications

 

Waste water pumps

 

Fuel injection pumps

 

Sealcon China supplies a wide range of seal products for pump. Both standard and custom-designed sealing products are available. Top-quality mechanical seals for agitator are also in stock. The top-quality seals can be used for various applications including ISO, DIN, API, etc. 7x24h postpurchase service is promised.

Mechanical Seal Material

  According to statistics, about 80% to 95% of the leakage of mechanical seals is caused by sealing faces and friction pairs. Flygt pump seals has this problem. In addition to keeping the sealing surface parallel, it is mainly the material problem of the friction pairs. The design of most mechanical seals uses stiffer materials to make the revolving surface, so that it can rotate friction on the soft stationary surface. The rotating surface is now made of stainless steel or harder material, such as tungsten carbide or silicon carbide. Graphite or Teflon is used for stationary surfaces.   Material selection of mechanical seal friction pairs is a complex problem. In general, it should be selected according to the properties of the working medium, pressure, temperature and rotation speed, and the ability to withstand short time friction when the pair is started or the liquid film is destroyed. Taking into account the above factors, the material of the friction pair should have th...

Pump Wear Plate

Image
Pump Wear Plate For users, the maintenance of daily use is more important to prolong their life, so the following two points must be done: tighten the wear-resistant plate (ring) of the nut regularly. After the use of a period of time, there is a little wear on the wear-resisting layer due to the existence of abrasive wear in the braided concrete cylinder, so that a small amount of wear is made on the wear-resistant layer, and the loosening of the locking nut will appear. The thrust ring is not compressed without producing elastic force. There will be a certain gap between the wear plate and the wear-resisting ring. At this time, the fine particles in the concrete will enter the wear plate and the wear-resisting ring, forming a low-stress abrasion wear. As the speed of wear is accelerated, the gap between the wear plate and the wear-resistant ring will become larger, making the large particles of concrete into the room, quickening the wear and scratch of the wear-resistant...
