| Parameter | Value/Description | Unit/Note | |
|---|---|---|---|
| Model | QT-GEA | Single/double mechanical seal for GEA pump series (e.g., Nutsche, Tetra Pak) | |
| Seal Type | - Hygienic Single Seal (for clean media) - Double Mechanical Seal with Barrier Fluid (for containment) |
Meets 3-A Sanitary and EHEDG standards | |
| Face Materials | - Primary: Silicon Carbide (SiC) - Secondary: Carbon Graphite with PTFE Impregnation |
SiC for durability; graphite for low friction in sanitary processes | |
| Housing Material | Stainless Steel 316L (Electropolished) | Surface roughness: Ra ≤0.5 μm, FDA-compliant | |
| Pressure Range | - Single: 0 - 1.4 - Double: 0 - 2.2 |
MPa | Double seal supports higher differential pressure for sterile environments |
| Shaft Diameter Range | 20 mm - 90 mm | Matches GEA pump shaft dimensions (verify model compatibility) | |
| Maximum Rotational Speed | 5500 | RPM | High-speed stability for centrifugal pumps in dairy/chemical industries |
| Temperature Range | -20°C ~ 160°C (Standard) - Up to 200°C (with FFKM elastomers) |
EPDM elastomers (standard) for food-grade use; FFKM for steam sterilization (SIP) | |
| Leakage Rate | ≤0.2 ml/h (Single) ≤0.03 ml/h (Double) |
Exceeds ISO 21049 and FDA 21 CFR Part 177 requirements | |
| Installation Type | Cartridge-Mounted (Clamp-Fit Design) | Tool-free installation for hygienic pipelines (compatible with GEA's QuickClean systems) | |
| Elastomer Material | EPDM (FDA-compliant, standard) - FFKM (optional) |
EPDM: pH 3-11 compatibility; FFKM: Resistant to pH 0-14 (aggressive chemicals) |
|
| Standards Compliance | 3-A Sanitary Standard 6040-2018, EHEDG, ASME BPE, CE | Certified for hygienic and sterile processes | |
| Key Features | - Mixproof Design (for double seals to prevent cross-contamination) - Self-Draining Geometry - Steam Sterilizable (up to 180°C) |
Critical for allergen-free production and pharmaceutical aseptic environments | |
| Application Notes | Ideal for GEA pumps in cheese production lines, pharmaceutical filling machines, and bioreactors. Double seals with sterile barrier fluid are essential for high-risk applications. |
Maintain regular inspection during CIP cycles and replace elastomers every 6 months in high-temperature environments. |
