Carbide mechanical seal ring for centrifugal pump

Entide has high-quality carbide sealing ring parts and carbide materials, which can effectively solve problems such as thermal cracks in mechanical sealing rings. It has the grinding equipment and capabilities for a series of smooth, frosted, concave and convex surfaces of sealing rings, which can better to serve our customers’ needs.

A centrifugal pump is a pump that uses centrifugal force generated when the impeller rotates to transport liquid. In order to prevent fluid or solid particles from leaking from between adjacent joint surfaces and to prevent external impurities such as dust and moisture from invading the internal parts of the machine and equipment. Carbide sealing rings are naturally indispensable. At the same time, the sealing ring, also called the mouth ring, can reduce the wear between the impeller and the pump casing and extend the life of the impeller and pump casing.

Generally, most of the seal leakage of centrifugal pumps is caused by seal end friction, so multiple considerations should be taken when selecting seal ring materials. It needs to have high temperature resistance, pressure resistance and pressure deformation resistance, dry wear resistance, high load resistance, good self-lubricating properties, strong corrosion resistance, and good air tightness. If the medium contains particles, carbide material should be selected. In this case, tungsten carbide mechanical sealing ring is a good partner of the centrifugal pump. Of course, various circumstances must be considered when selecting the material of the tungsten carbide. For example, if you need good corrosion resistance and can be used at high speeds, you can choose YG3. If you need high wear resistance and a certain impact toughness, it is often used as a dynamic and static ring material, you can choose YG6.
