EL Series new generation Metal Face Seals product by SAP Parts™ involves active sealing surface coated by High Velocity Oxygen Fuel (HVOF) coating of WC-CO-Cr ( 6-10- 4)that gives higher wear life. Also the sealing surface exposed to environment is coated with special Anti- Corrosion Cr3C2 + NiCr coating forming a hard layer.

3. Technical Data & Application Conditions. Page 3 Technical Data:  1.Field of application: Mining industry, open pit mines 2.Expected lifetime: 30.000 working hours 3.Ambient condition: Extremely dusty, ice, water, mud 4.Humidity (rel.) 0% to 100% 5.Temperature: -40°C / +50°C 6.Road conditions: Truck can sink in mud up to center of wheel hub. Snow, oil sands, wet gravel, dry gravel Dust suppression liquid may be other than neutral PH Other Considerations: The truck is commonly cleaned with high pressure steam cleaner. The water 0,15 mm peak to peak max. vibration. 1.Rotational speed: max. 90 1/min 2.Oil temperature: - 40°C / +90°C 3.Oil quality: DIN 51517-3 CLP-HC 320 4.Oil pressure: From inside, max. 0,3 bar Oil Sand Specifications: Clay Lens, Connate Water , Silica Sand, Fine Clay, Bitumen, Quartz, Slit, Water. A typical oil sands deposit contains about 10% bitumen, 5% water and 85% solids. However, the bitumen content can be as high as 20% in some sections. The solids contained in oil sands deposits are primarily quartz silica sand (usually over 80%), with a small fraction of potassium feldspar and fine clays. Clay minerals typically consist of kaolinite, illite, chlorite and smectite. Deposits that have a high fines content tend to have a lower bitumen content. © SAP PARTS PVT.LTD. 85,B.U.Bhandari Indl.Esatate, Sanaswadi, Pune 412208 INDIA – www.sapparts.com
