Applications mechanical seal 4ksbm6t & D
PI 682 applications in the chemical and petrochemical industries
Design mechanical seal 4ksbm6t & D
- Double cartridge seal
Technical Data mechanical seal 4ksbm6t & D
- Pressure: Up to 42 bar
- Temperature: -10 to 176 °C
Benefits mechanical seal 4ksbm6t & D
The double cartridge seal can be connected to all common API Plans, such as 01, 02, 11, 31, 32 + 52, 53 (A, B, C) and 23 + 52, 53 (A, B, C). The seals are available for all of KSB’s API pumps.
The space between the two mechanical seals is flushed with a buffer or barrier fluid, depending on the application. This completely absorbs any leakage of the fluid pumped. In addition, the heat is transported away from this area. The double pressure balanced mechanical seal can be operated with pressurised barrier fluid or unpressurised buffer fluid.
Configurable flange connections
For API Plans 11, 12, 21, 22, 23, 31, 32, 41, +53 (A, B, C), +54, +61 (62).
Fixed throttling bush
Optionally floating.
Three strong torque transmitting elements
For transmitting the rotation and for vibration damping.
Seal face material
Combination of hard and soft materials, e.g. silicon carbide (versus carbon graphite), highly resistant to blistering.
Multi-spring arrangement
Made of C276 alloy
Rotating flexible elements
With O-ring as secondary seal.
Optional cooled gland packing chamber
(Plan 02) and connections for Plan 23 with high-efficiency pumping ring
