Dual Cartridge Type John Crane Type 5620 Mechanical Seal For Pump Use 24 mm to 140 mm
Dual cartridge type John Crane Type 5620 Mechanical Seal For Pump use
Suggested Operation Limits:
The type seal can replace with Johncrane type 5620D cartridge seal
1,Provides the safety of dual seal without an external lubrication system
2,Optimized primary ring for low emission performance
3,Set-screwless outboard seal drive
4,Register fit enlarged-bore gland plate
5,Reversible seal head for rotating and stationary operation
Double end, multiple springs, balanced, independent rotary direction, still structure, clamp transmission and cartridge seal. The compensation components are assembled into the flange and the elastomers protects the springs from the mediums to make sure the springs will not be jammed. Multiple springs make the loads on the seal faces balanced. The second end seal at the sealant side accomplish the second sealing and prevent the leakage of the mediums and sealants. The sleeve are supported by the elastomers on the shaft and there is no axial movement and no damage to the shaft. The seal faces are close to the rotor and have high cooling and lubrication efficiency. The special design of this seal can work with counter pressure and there are diversion trenches inside the flange so that the cooling effects are evenly distributed. This seal has to work with flush system and the sealant pressure should be 0.1 - 0.3 MPa and flow rate should be 3 - 8 L per minute.
