Type 1
The Type 1 is a full convolution industrial-duty elastomer bellows seal, known for its exceptional performance across a wide range of service conditions. Ideal for pumps, mixers, compressors, and other rotary shaft equipment, it’s trusted by industries like pulp and paper, petrochemical, food processing, and more.
| Product Information | Details |
|---|---|
| Drive Band and Notches | Absorbs both breakout and running torque, preventing overstressing of bellows |
| Slippage Elimination | Protects the shaft and sleeve from wear and scoring |
| Automatic Adjustment | Compensates for abnormal shaft-end play, run-out, primary ring wear, and equipment tolerances; Uniform spring pressure compensates for axial and radial shaft movement |
| Special Balancing | Accommodates higher-pressure applications, greater operating speeds, and lower wear |
| Spring Design | Non-clogging, single-coil spring offers greater dependability and will not foul due to fluid contact |
| Low Drive Torque | Improves performance and reliability |
| Temperature Limits | -40°F to 400°F / -40°C to 205°C (depending on materials used) |
| Pressure Limits (Type 1) | 425 psi(g) / 29 bar(g) |
| Pressure Limits (Type 1B) | 1200 psi(g) / 82 bar(g) |
