The NM-5 is a highly reliable Rubber Bellow Mechanical Seal, engineered for general to heavy-duty industrial applications. Its full-convolution elastomeric bellow design provides superior flexibility, allowing it to compensate for significant shaft end-play and run-out without compromising the seal.

Known for its robustness, the NM-5 utilizes a single coil spring and a drive band mechanism, making it an excellent solution for process pumps, mixers, and equipment handling water, oils, and industrial slurries.

Seal faces materials:

• Resin impregnated carbon (В)
• Silicone carbide (Q₁, Q₂)
• Ceramic Al₂O₃ (V)

Elastomers:

• Fluorcarbon rubber, FKM (V)
• Nitrile-butadiene-rubber (P)
• Ethylene propylene rubber, EPDM (E)
