Product Description:
Designed in accordance with API 682 for boiler feed pumps and other rotating equipment. It is rated for a pressure of up to 5.0 MPa. It includes shaft sleeve, rotating ring, stationary ring, auxiliary seals, compensation components, seal gland，and drive mechanism.
Technical Features:
1.High-strength seal materials for optimal performance.
2.Balanced design with precisely calculated face pressure ratio to reduce face load and minimize heat generation.
3.Stationary multi-spring design provides excellent followability, reduces centrifugal effects on springs, and maintains stable spring and sealing performance.
4.Large-cross-section sealing rings maintain floatability while enhancing sealing performance.
5.The sleeve can be driven by a key and secured with axial threads or splines, effectively resisting high-pressure thrust.
Solution Selection:
Optional Plan 02 front jacketed cooling (depending on conditions). Forced circulation seals apply to Plan 23.
