BPI-MDJ-Low-Pressure Double End-face Unbalanced Containerized Mechanical Seal

Application Scope:

• Media: Alumina slurry, gypsum slurry, coal washing slurry, tailings slurry.
• Temperature: <120°C.
• Pressure: <0.9 MPa.
• Linear velocity: <10 m/s.
• Shaft diameter: Φ35-Φ175mm.

Structural Features:

• The mechanical seal structure is a double end-face unbalanced type, containerized, with no steps on the sleeve. When installing in the pump chamber, the axial movement of the mechanical seal is not restricted by the sleeve.
• The sealing device is equipped with a pressure gauge, facilitating the measurement of the sealing water pressure to prevent premature failure due to insufficient sealing water.
• The sealing water can be recycled without entering the medium flow, ensuring no impact on the process.
• For specific material selection, please consult Beta Prime Industry.

Instructions for Use:

1. During installation, lubricate the inner hole of the sleeve and the O-ring seal with lubricating oil (ethyl propylene rubber should not be coated with petroleum-based lubricants) for easy installation.
2. Connect the end with the pressure gauge to the sealing water outlet through a tee, and the other end to the sealing water inlet through a valve.
3. The sealing water pressure should be higher than the pressure in the sealing chamber by 0.1-0.2 MPa.
4. Before starting the pump, open the sealing water 5 minutes in advance and close it 5 minutes after stopping the pump.
5. The sealing water must maintain stable and continuous pressure during pump operation.
