Mechanical Seal

Topbon Mechanical seals are engineered for most pumps, mixer and agitator applications in maintenance.Our mechanical seals can replace for John crane's, NSO'S,Burgman's and Pacific's seals.In many cases the designs have been proven to be workhorse over years of use.In others seals must be designed for evolving industrial demands.

Mechanical Seals-Face Materials

Tungsten Carbide-Tungsten carbide is widely used as seal faces with resistant-wearing, high fractural strength, high thermal conductivity, small heat expansion co-efficient. It is the best material to resist heat and fracture in all hard face materials. Carbon –Graphite has the good property of good resistant-corrosion, high thermal conductivity and lower friction, good self-lubrication, the smaller expansion. They can be made into the seal faces, bearing and so on. It is ideal to choose it as the frictional mating rings. Silicon Carbide-Silicon Carbide Seal Face have the property of excellent resistant-corrosion, high mechanical strength, high thermal conductivity,good self-lubrication, used as seal faces, bearings and tubes in spacecraft, machinery, metallurgy, printing and dyeing, foodstuff, auto industry, pharmaceutical and so on. Ni-resist-Is a form of Stainless steel which has had nickel added to it to lower the friction generated by the rotating face. It is an inexpensive seal face and ideal for fresh water applications. Ceramic-Ceramic seal faces have the property of the resistant-high-temperature, resistant-corrosion, resistant-wearing and good sealing and are widely used in spacecraft, machinery, metallurgy, printing and dyeing, foodstuff, pharmaceutical, auto industry and so on.

Customization Stock Management:

According to customer requirements , we can prepare the spare parts of mechanical seal's stocks for our customer , so that can shorten the delivery times , most importantly can reduction the financial pressure for our customer !
