This mechanical seal is specially designed for mud pump applications under high-abrasion and high-solid-content working conditions. It is available in two structural types—external cooling (ZGJ) and internal flushing (ZHJ)—to meet different sealing requirements in drilling and slurry transportation systems. The design ensures stable performance, reliable operation, and long service life in harsh industrial environments.
Structural Features
- ZGJ external cooling mechanical seal, where flushing water does not contact the process medium, operating under atmospheric pressure conditions
- ZHJ internal flushing mechanical seal, suitable for media in contact with flushing water, with flushing pressure at least 0.1 MPa higher than medium pressure
- Flexible selection of sealing structure according to operating conditions
- Stable sealing performance under high abrasion and complex working environments
