General characteristics
Single seal, balanced, multi-spring, cartridge design – easy assembly and disassembly of the seal, heat removal from the gland space – cooling system acc. to API 610 Plan 23, vibration resistant – elastic support of the stationary ring, solid slide rings – resistant to thermal deformations, acceptable shaft axial displacement ±3 mm (in special embodiments ±6 mm), period of trouble-free service > 40,000 hours.
Range of sizes available
- Shaft diameter: d = 25 ... 140 mm
Operating parameters
- Pressure: < 6.0 MPa
- Temperature: < 200 °C
- Velocity: v < 25 m/s ; pv = 120 MPa m/s
Applications
BC seals are designed for operating with hot water. They are used in boiler water main and preliminary feed pumps. Developed construction solutions cover the whole range of pumps used in Polish power and heat generating plants.
We also offer the version BC2 seal with integrated internal cooler. The same rule of cooling effect forced by the rotating movement is kept, and all components and the method of mounting on the shaft are standard – the cooling system, however, has been optimised and designed in a specific way.
