Features:
Grundfos mechanical seal GRF-E is a pump seal which fit for
grundfos pump model CRK2/CR4/CRK8/CRK16, CRK2/4 AUUV, CRK8/16 AUUV,
CRK2/4
This grundfos seal is a unbalance seal with oring component, Robust
O-ring seal featuring a rigid torque transmission design required
for hard material pairings (WC/WC or SiC/SiC), even where
lubrication is poor. The dynamic secondary seal is an O-ring. This
involves a risk of wear on the shaft under the O-ring and of seal
hang-up (blocking of axial movement of the rotating seal ring).
Users can choose carbon, silicon, and tungsten carbide for this
mechanical seal as seal face, if for high temerperature, we suggest
to choose rubber seal for the rubber parts.
Operating Limited:
| Shaft diameter | 12 and 16mm |
| Pressure | up to 3Mpa |
| Temperature | -20~180°C |
| Slidingvelocity | 15m/s |
Material:
| Rotary Ring | Car / SIC/TC/Cer |
| O-Ring | , EPDM, NBR, AFLAS, Kalrez,PTFE |
| Spring and Metal Parts | SUS304, SUS316, HAST C |
| Stationary Ring | Car / SIC /TC/Cer |
Advantages:
• Spring unit averted from the product so no sticking and clogging
of the springs
• Safe operation (no fractures) because of seal face locking by
square pin
• Suitable for pressure reversals
• Operation in vacuum without additional seat locking possible
• No damage of the shaft by a dynamically loaded O-Ring
• Small installation sizes
• Best suitable for conversions, no adaptations of the pump
• Insensitive to solid containing and abrasive media
• Advantages of a balanced seal even with plain shafts
• Insensitive to shaft movements because of the stationary design
Application:
• Water and waste water technology
• Chemical industry
• Refining technology
• Dirty, abrasive and solid containing media
• Fugitive hydrocarbons (no API seal!)
• Sticky and stringy media
• Chemical standard pumps
• Sewage pumps
