Elastomer Bellow Mechanical Seal Basics

Elastomer bellows mechanical sealis identified by the use of a unique elastomer bellowsor 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. Metric mechanical pump sealscan 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 China rubber bellowswhich 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 sealis 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 Mechanical 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.
