Overview
The NPS 200 shaft seals are precision-engineered mechanical sealing components used in industrial pumps, motors, and rotating equipment. These seals are designed to prevent fluid leakage around rotating shafts while maintaining pressure and temperature integrity in demanding applications. The NPS 200 model serves industries including water treatment, HVAC, process industries, and general industrial maintenance where reliable shaft sealing is critical.
Key Features
- Mechanical end-face seal design for dependable fluid containment
- Compact, unitized construction for streamlined installation
- Rated for general industrial duty in centrifugal and rotary pump applications
- Elastomer bellows provide flexibility to compensate for shaft movement and wear
- Factory-assembled single-piece design enables rapid changeover
Technical Specifications
Verify exact specifications with NPS documentation before ordering, as the NPS 200 model may support various shaft diameters and seal heights depending on application variant:
- Seal Type: Mechanical face seal, single-spring design
- Construction: Elastomer bellows, molded faces
- Standard Pressure Rating: Up to 75 PSI (typical for this class)
- Temperature Range: -40°F to +400°F (standard range for elastomer seals)
- Material Faces: Carbon and ceramic (typical for industrial duty)
- Elastomer Material: Buna-N or equivalent (fluid-resistant)
Typical Applications
- Centrifugal water pumps (industrial and municipal)
- Deep well and shallow well jet pumps
- HVAC circulating pumps
- Wastewater and sewage pump systems
- General industrial rotating equipment requiring shaft sealing
