Double Cartridge Mechanical Seals for pumps
Mechanical Seals - Double Cartridge A double cartridge type mechanical seal is a pre-asseled package of seal components (including 4 seal faces) making installation much easier with fewer points for potential installation errors to occur. Why Double Cartridge
NTST General Information: NTST has developed the capability to fabrie B4C coatings using thermal spray technology. This material is extremely difficult to deposit using the air plasma spray process (APS), and this capability is unique to NTST. NTST has developed both pure B4C coatings and B4C cermets (B4C+TI, B4C+Ni). The pure B4C coatings were designed for use in the food processingNew page

Seal Reliability | Choose the right seal ring material …
17/1/2003· Tungsten carbide, another common seal ring material, is made by heating tungsten carbide powder and a metallic binder to 2,700 F (1,500 C) to melt and fuse the binder. This produces an extremely tough, hard ceramic-metal (cer-met), which has good abrasion resistance and is more dense than other seal ring materials (see Figure 4).
