MECHANICAL SEALS FOR PUMP

• 

Mechanical seal for pump is a kind of dynamic seal assembly, which is widely used on the rotating shaft. It is also known as the end seal. Consisting of at least a pair of end faces which are perpendicular to the rotating shaft, mechanical seal acts on the end surface through fluid pressure and compensation mechanism (elastic force or magnetic force). In addition, auxiliary seal makes the joint surface stick and keep relative sliding, so as to prevent fluid leakage.

Different Types of Water Pump Seal

Elastomer Rubber Bellow Mechanical Seals

Developed with rubber bellow, this type of seal is widely used for water, oil and other light duties applications. Both standard and OEM elastomer bellows seals are available.Most of our rubber bellow seals can easily replace your pump seal.

Metal Bellow Mechanical Seals

Compared with common pusher seals, metal bellow seals have more advantages. The structure eliminates seal hang-up and has a long service life. It is widely used in high temperature application. Browse the page to see more about our products.

Double Cartridge Mechanical Seals

The working principle of mechanical seal for pump 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. Mechanical seals are often used in rotating machinery, such as pumps, compressors, and reaction stirred kettle.

Mechanical Seal Function in Pump

There are 2 common sealing methods of the pump: mechanical seal and soft packing seal. Each of them has different characteristics and they are also suitable for different occasions. The correct selection of mechanical seals is beneficial to reducing the cost and improving the working efficiency.

Compared with the soft packing seal, the mechanical seal for pump has the following advantages:

Mechanical seals for pump have complex structure, higher requirements and cost. And the operators needs to have a certain level of technology, such as the basic knowledge of fitter and the characteristics of the mechanical seal.
