Model |
QT-WB2 |
External-mounted, single-face, balanced PTFE bellows mechanical seal |
|
Seal Type |
Single-End Face, Balanced, PTFE Bellows Drive |
Independent rotation direction, driven via bellows |
|
Rotating Face Materials |
Carbon Fiber, 99% Alumina Ceramic, Silicon Carbide (SiC), Filled PTFE |
Carbon fiber for low friction; SiC for high wear resistance |
|
Stationary Face Materials |
Ceramic, Silicon Carbide (SiC) |
Ceramic for general corrosion resistance |
|
Metal Components |
Spring, Retaining Ring - SUS304/SUS316L Stainless Steel |
SUS316L for higher corrosion resistance |
|
Pressure Range |
≤0.8 |
MPa |
Suitable for low-to-medium pressure applications |
Temperature Range |
-30°C ~ 150°C |
PTFE bellows maintain elasticity in wide thermal range |
|
Maximum Rotational Speed |
3000 |
RPM |
Limited by PTFE bellows dynamic performance |
Axial Movement Compensation |
±0.5 |
mm |
Bellows compensate for shaft axial runout |
Key Features |
- Chemically Inert Wetted Parts
- Metal Components Isolated from Process Liquid
- High Corrosion Resistance (pH 0-14) |
Ideal for aggressive chemicals like concentrated acids, alkalis, and oxidizing agents |
|
Installation Type |
External Mount (Non-intrusive to pump housing) |
Simplifies replacement without disassembling pump |
|
Applications |
Paper manufacturing, salt production, fertilizer/pesticide processing, chemical pumps (fluoroplastic-lined, acid/alkali pumps) |
Compatible with fluorinated plastic pumps and lined equipment |
|
Media Compatibility |
Concentrated sulfuric/nitric acid, sodium hydroxide, salt solutions, oxidizing agents |
Avoid abrasive slurries (risk of face wear) |
