Z9500(Z9501+Z9502) Mechanical Seal for Polypropylene Loop Reactor Axial Flow Pump

Operating Parameters
● Pressure: ≤6MPa ● Temperature: -40~260℃ ● Shaft Diameter: 30~160mm ● Speed: ≤3000r/min ● Linear Velocity: ≤25m/s The above limit application parameters are not met simultaneously, customized design for particular applications.
Product Description
● It is used in axial circulation pumps for loop reactors in polypropylene and polyethylene plant.
Structure Features
● The special arrangement of the three-face seal structure is safe, stable and highly reliable. ● Front-mounted combined throttling device design can ensure the external flushing effect. ● Seal with bearings, it can withstand equipment radial loads. ● The special groove and runner design of the main spiral sleeve ensures the heat exchange effect of the  isolation fluid circulation. ● Bi-directional balanced design for the first stage seal, it can accommodate abnormal differential  pressure fluctuations. ● High-pressure resistant structural design for the second stage, seal faces are specially treated, it can  keep zero deformation with optimal lubrication. ● Optimized design of the integral pumping ring for the third stage, it can circulate heat efficiently.
Recommended Applications
● Refining and Petrochemical Industry
Piping Plans
● API682 PLAN32,53C,52
