Mechanical seals including tungsten carbide seals and silicon carbide seals are used increasingly on fluid pump to replace packed gland and lip seal. Pump with mechanical seals perform more efficiently and generally perform more reliably for extended periods of time.

Because tungsten carbide seals are of good wearable resistance, great anti-bend strength, high thermal conductivity, small co-efficient of expansion, they have a very wide range of applications. Tungsten carbide seals also have the highest co-efficient of heat shock among all the hard surface material.

Tungsten carbide seals are extremely tough and stiff and have very good abrasion resistance. Tungsten carbide seals have versatile seal faces like Silicon Carbide. Tungsten carbide seals are very hard like silicon carbide seals; however they are very heavy to the touch, making them easy to distinguish from silicon carbide.

Tungsten carbide is widely used as seal faces with resistant-wearing,high fractural strength,high thermal conductivity,small heat expansion coefficient.It is the best material to resist heat and fracture in all hard face materials.

We design and fabricate wide array of tungsten carbide seals that are manufactured from qualitative raw material. These seals find wide application in various industries and are known for their strength and long service life. Our tungsten carbide seals are available in different diameters as specified by our clients. They can withstand wide ranges of temperature and pressure.
