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
