Rotary Shaft Seals Screw Conveyor

BL-D complies with Meiwei FDA certification. The static ring and movable ring of the shaft seal are made of high-performance modified PTFE material, PEEK1000 and special metal processes. The shaft seal installation base, 0-ring, static ring, movable ring, and end cover can be made into a partial structure, which is easy to maintain and replace. It can also be used for on-site demolishing-free upgrades and replacement of equipment filler seals, skeleton oil seals and mechanical seals.

Rotary shaft seals in screw conveyors play a vital role in ensuring the containment of bulk materials and preventing the ingress of contaminants at the interface between the rotating shaft and stationary housing. These seals are especially important in industries such as agriculture, food processing, mining, and chemicals, where screw conveyors handle abrasive, dusty, or corrosive materials. Effective sealing solutions must accommodate shaft misalignment, vibration, and varying temperature conditions, while resisting wear and chemical degradation.

Materials commonly used include high-performance elastomers, PTFE, and composite materials designed for durability and minimal maintenance. A properly selected rotary shaft seal improves system efficiency, reduces product loss, and extends the service life of both the conveyor and surrounding equipment. This paper examines the key design considerations, material choices, and performance requirements for rotary shaft seals in screw conveyor applications. Emphasis is placed on sealing reliability under continuous operation and harsh environmental conditions, offering insights into optimizing seal performance to support safe, clean, and efficient material transport.
