VIKING gear pump It is a commonly used industrial pump, widely used in chemical, petroleum, food, pharmaceutical and other industries. Using VIKING Gear pump The choice of sealing material is very important. The quality of the sealing material directly affects the performance and service life of the pump. Therefore, it is critical to select the sealing material correctly. In this article, we will introduce the choice of sealing materials for VIKING gear pump.

First, we need to understand the sealing method of VIKING gear pump.

There are two main sealing methods for VIKING gear pump: mechanical seal and packing seal. Mechanical seal is realized by mechanical structure. Packing seal is realized by packing material. Both sealing methods have their own advantages and disadvantages. Mechanical seal is widely used and has good sealing effect, but its service life is relatively short; The service life of packing seal is relatively long, but the sealing effect is not as good as that of mechanical seal.

next, Viking We will introduce the types and characteristics of sealing materials commonly used in VIKING gear pumps.

Rubber sealing material

Rubber sealing material is the most widely used sealing material at present. Common rubber sealing materials include NBR, fluororubber, silicone rubber, etc. Rubber material has good corrosion resistance, wear resistance, high temperature resistance and other advantages, but it is not oil resistant. It is generally suitable for water and gas pumps.

Polytetrafluoroethylene (PTFE)

Polytetrafluoroethylene (PTFE) is a kind of polymer composite material. PTFE sealing material has the advantages of high corrosion resistance, good wear resistance, low temperature resistance, high mechanical properties and chemical stability. PTFE sealing materials are generally suitable for pumps with strong corrosive media and high-temperature media.

Graphite sealing material

Graphite sealing material is a porous material. Graphite sealing materials have good corrosion resistance, high temperature resistance, wear resistance and other advantages, as well as high mechanical properties and chemical stability. Graphite sealing material is suitable for pumps with high temperature, high pressure and strong corrosive media. IMO

Ceramic sealing material

Ceramic sealing material is a new type of sealing material, which has good wear resistance, corrosion resistance, high temperature performance and high pressure performance. Ceramic sealing materials have a long service life and good sealing effect. Ceramic materials are generally suitable for pumps with strong corrosive media and high-temperature media.

In a word, the selection of sealing materials for VIKING gear pump should be based on the characteristics of the medium, the temperature and pressure of the medium, the working conditions of the pump and other factors. Appropriate sealing materials can greatly improve the service life and performance of the pump.
