从China供应商批发进口22451-1 Mechanical Seal — FOB条款

22451-1 Mechanical Seal is a pump seal supplied for Mission Magnum pump sizes 3x2x13, 4x3x13, 5x4x14, 6x5x11, 6x5x14, 8x6x11, 8x6x14 and 10x8x14. The source description identifies it as a Type 1-2 seal and lists equivalence to Mission pump seal NOV numbers 22451-1 and 648414308. The same range also references 22451-2, 648414340, 22451-3, 648414357 and 22451-9A for alternative face combinations. Listed dimensions are 3.5 inch, 2.5 inch, 1.875 inch and 1.5 inch.

The stated construction includes tungsten carbide, Viton and SS316 machining parts, with the 22451-1 version specified with tungsten carbide faces. Other variants in the same family are given as ceramic to carbon, silicon to tungsten, and silicon carbide face arrangements. In slurry pump service, these face combinations are typically selected according to abrasion level, fluid chemistry and running conditions, with tungsten carbide and silicon carbide commonly used where wear resistance matters. A mechanical seal set is stated to include the mechanical seal, 3 pieces of packing and a pin.

This item is relevant to buyers maintaining drilling, solids control and slurry handling pumps that need a direct replacement by part number and pump size. Before ordering from Hebei Tobee Pump Co., Limited, the buyer should match the exact P/N, seal face combination and nominal size against the installed pump, because several closely related variants are listed together. The source does not state MOQ, lead time, pressure rating or Incoterms, so those trade terms need to be confirmed with the supplier before purchase.

Hebei Tobee Pump Co., Limited is the named supplier for this seal, and the profile address places it in Shijiazhuang, 050000, China. The listing ties the company directly to pump spare parts for Mission Magnum equipment by giving multiple compatible pump sizes and several related seal part numbers in the same family. That level of part-number detail is useful for maintenance buyers comparing replacement options by installed pump model rather than by a generic seal description.

The supplier profile also shows a harbor trust tier. At the same time, the profile currently shows a 0.00 response rate and 0 average response hours, so contact-performance data is either not established or not reflected in the listing and should be verified directly with the supplier. The listing does not state factory capacity, certifications, export markets, lead times or minimum order quantity, so those points remain open items for buyer confirmation.
