3B Mechanical Seals & 3B-1 Mechanical Seals
3B & 3B-1 mechanical seals are multiple-spring designed, available in both balanced and unbalanced configurations. You can get a basic 3B and 3B-1 seal for single, dual, or tandem conditions.
3000 Series mechanical seals can be custom engineered to accommodate various operating conditions as well as a wide variety of different types of equipment.
FEATURES:
- Normally cartridge mounted for ease of installation and equipment accommodation
- Can be used as either a rotating spring design or as a flexible stator design depending on operating parameters
- Required seal face designs and balance ratios can be calculated to ensure optimum performance
- Can be furnished with pumping ring or circulating shroud for API Plan 23 or 53 operation
TYPICAL APPLICATIONS WOULD INCLUDE:
- Refinery & Petrochemical Light Hydrocarbon Services
- High Pressure Multistage Pumps
- Circulating Water and Cooling Water Services
- Boiler Feed Pump Applications
- Specialty Equipment Applications
