Screw Conveyor Rotary Shaft Seals
Rotary shaft seals in screw conveyors are essential for preventing material leakage and protecting internal components from external contaminants such as dust, moisture, and chemicals.
Product Description
BL-DJ 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 partial structures, which are easy to maintain and replace. It is also used for on-site demolishing-free upgrades and replacement of equipment filler seals, skeleton oil seals and mechanical seals. The shell is a double-end heat runner.
Rotary shaft seals in screw conveyors are essential for preventing material leakage and protecting internal components from external contaminants such as dust, moisture, and chemicals. These seals are installed at the points where the rotating screw shaft exits the conveyor housing, ensuring a tight seal that maintains process integrity and supports efficient, continuous operation.
Screw conveyors often handle abrasive, corrosive, or high-temperature materials, requiring seals made from durable and chemically resistant materials like PTFE, Viton, nitrile rubber, or stainless steel. These seals must also withstand constant motion and pressure differentials without degrading performance.
Effective rotary shaft sealing helps minimize downtime, reduce maintenance frequency, and extend equipment life. Choosing the right seal design and material is crucial for ensuring reliable operation in demanding bulk handling and material processing environments.
