The NM-2100 is a compact and robust Rubber Bellow Mechanical Seal, specifically engineered for applications with limited installation space. Its modular design features a single coil spring and an elastomeric bellow that adheres to the shaft, providing maximum durability and operational reliability.

This seal is designed to handle high pressure and temperature fluctuations, making it an excellent choice for centrifugal pumps handling water, oil, and weak chemicals.

Seal faces materials:

• Resin impregnated carbon (В)
• Antimony impregnated carbon (A)
• Spec. CrMo steel (Е)
• Tungsten carbide (U₃)
• Silicone carbide(Q₁, Q₂)
• Ceramic Al₂O₃ (V)

Elastomers:

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

Operation conditions:

• p = 16 bar
• t = -20 … 140°C
• v = 10 m/s
