The above limit application parameters are not met simultaneously, customized design for particular applications.
Product Description
● It is often used at the end of extrusion pelletizer screws in polyethylene and polypropylene plants.
● It is a double dry seal for sealing solid material powders by introducing an external air source,no
leakage of medium into the atmosphere.
● Seal structure and material has applied for a number of patents, it has a large number of successful
applications in polypropylene plants.
Structure Features
● Simple structure, compact size, easy to install.
● The main part is designed as a fully sectionalized structure, replacement of seals without dismantling
the unit.
● External spring, it will not be clogged with material.
● The specially designed rubber rectangular ring can be adapted to the poor smoothness and low speed
of the equipment.
● The friction pair is made of the company's patented material and treated with special process, resulting
in a long service life and resistance to dry friction.
● Adjustment of sealing performance can be achieved by adjusting the pressure of an external air source
or an external spring. It is time-saving, convenient maintenance, and low running costs.
Recommended Applications
● Refining and Petrochemical Industry
● Coal Chemical Industry
