Applications mechanical seal 4ksbm6s
API 682 applications in the chemical and petrochemical industries
Design mechanical seal 4ksbm6s
- Single cartridge seal
Technical Data mechanical seal 4ksbm6s
- Pressure: Up to 42 bar
- Temperature: -10 to 176 °C
Benefits mechanical seal 4ksbm6s
The single cartridge seal can be connected to all common API Plans, such as 01, 02, 11, 31, 32 + 51, 61 (62) and 23 + 51, 61 (62). The seals are available for all of KSB’s API pumps.
The throttling bush enables connection to a gas, steam or liquid quench, depending on the seal variant. This prevents outboard incrustations at the seal.
The API Plan combination 02 + 23 with high-efficiency pumping ring is perfectly matched to applications with hot fluids.
Configurable flange connections
For API Plans 11, 12, 21, 22, 31, 32, 41 + 61 (62) and 23 + 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 and carbon graphite, which is 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
