Import 22451-1 Seal, Mechanical — Buy in wholesale FOB from Supplier in China

The 22451-1 Seal, Mechanical is a tungsten carbide faced mechanical seal engineered for Mission Magnum type centrifugal pumps, interchangeable with NOV part number 648414308. This seal measures 3.5 inches in its largest variant, with additional sizes at 2.5 inch, 1.875 inch and 1.5 inch to suit different pump configurations. The seal assembly incorporates tungsten carbide faces, Viton elastomers and SS316 machined components, delivering abrasion resistance in abrasive slurry service.

Tungsten carbide faces provide exceptional hardness and wear resistance, typically achieving hardness values between 1600-1800 HV30, which suits high solids content applications. Viton (FKM) secondary seals tolerate temperatures from -26°C to 204°C and resist petroleum-based fluids and many chemicals. SS316 housings and springs withstand corrosive environments better than 304 stainless steel. The supplier also lists ceramic-to-carbon, silicon-to-tungsten and silicon carbide face variants under related part numbers, broadening chemical compatibility options.

Mission Magnum pump seals see primary use in oilfield drilling mud circuits, mining slurry transfer and industrial wastewater handling. Buyers include pump rebuilders, oilfield service companies and mining maintenance departments. Each seal set ships with three packing rings and a retention pin. The packing shaft lantern rings are offered in graphite, King brand, Teflon and Kevlar materials for different thermal and chemical demands. Confirm exact seal size, face material and elastomer grade with the supplier before ordering, as application fluid chemistry and temperature dictate optimal material selection.
