Packing Material Options for Flanged Gland Seals

Introduction

KWS Flanged Gland Seals utilize braided rope packing to create a positive seal around the drive and tail shafts of screw conveyors, drag conveyors, and bucket elevators. The packing material consists of ½-inch square braided rope that fits tightly in the outer housing and around the diameter of the shaft. The seal follower is tightened to compress the packing and create a seal between the shaft and housing. Rope packing is available in many different materials to help satisfy any condition.

Features

Multiple Rings of Packing – Individual packing rings serve as sequential sealing elements, with up to five rings can be used to achieve proper shaft sealing.

Variety of Braided Rope Packing Materials

Graphite Impregnated Packing – Commonly specified for many industrial sealing applications with thermal resistance up to 800-degrees F.
Teflon Packing – Demonstrates superior performance in chemically aggressive environments and is resistant to a broad spectrum of chemicals, acids, bases, and solvents. Well-suited for critical applications in chemical processing.
Ceramic Fiber Packing – Excels in extreme thermal conditions at temperatures reaching 2,300-degrees F. Preferred choice for high-temperature applications that exceed the operational limits of standard sealing materials.

Benefits

Ease of Maintenance – Braided rope packing can be replaced in minutes by sliding the follower back to allow access to the packing.

Cost Effective – Seal follower is adjusted to compensate for packing material wear without replacement.

Self-Lubricating – Rope packing materials have natural lubricating characteristics, minimizing maintenance requirements.

Low Leakage Rates – Braided rope packing provides excellent sealing with minimal leakage, helping meet environmental regulations and reducing bulk material loss.
