• Torque Transmission: The conical spring grips the shaft to transmit torque, eliminating the need for drive pins or set screws that can slip or damage the shaft.

• Self-Aligning: The flexible design allows the rotary face to adjust automatically to shaft end-play and minor misalignment.

• Optimized Spring Rate: The spring design is tuned to provide adequate face loading in a shorter compressed length, ensuring a tight seal without excessive face wear.

• Shaft Protection: The interference fit of the spring and rubber bellows protects the shaft area under the seal from corrosion.

• Balanced Design: The stepped face geometry allows the seal to handle higher pressures (up to 25 bar) without face separation or excessive heat generation.

• Torque Drive: Features robust drive pins or lugs to transmit high torque, essential when pumping viscous fluids like oil or resin.

• Self-Cleaning: The open conical spring allows solids and fibers to be spun out, preventing the spring from becoming blocked in dirty water.

• Positive Drive: The spring grips the shaft to drive the seal face, ensuring reliable rotation even in heavy slurry.

• Low Friction: The dry-running carbon formulation generates minimal heat, preventing face damage in gas-phase operation.

• FDA Compliance: Available with FDA-approved dry-run materials for use in food and pharmaceutical mixers.

• Protected Spring: The wave spring is often shielded or located outside the fluid path, preventing it from fouling with product.

• Torque Drive: Uses robust drive pins to transmit torque, ensuring the seal face rotates positively even in thick fluids.

• Loose Face Fit: The seal face is loosely inserted into the driver, allowing it to self-align and reducing the risk of heat distortion transfer from the shaft.

• High-Pressure Capability: Capable of handling pressures up to 25 bar (or higher in special designs) due to its balanced nature and strong drive mechanism.

The dry gas mechanical seals designed as direct replacements for EagleBurgmann seals in monoblock pumps. Engineered for reliability and efficiency, our seals ensure zero leakage, reduced energy consumption, and extended equipment lifespan in demanding industrial applications.

• Bellow Protection: The elastomer bellow covers the shaft, protecting it from corrosion and wear, while transmitting torque through friction grip.

• Dry Face Technology: Utilizing specific Carbon grades that can operate without a continuous liquid film, ideal for top-entry mixers or pumps that may run dry briefly.

• Unbalanced Flexibility: The flexible bellow design accommodates significant shaft misalignment and end-play, making it forgiving in worn or older equipment.

• No Shaft Fretting: The bellow grips the shaft tightly, ensuring no dynamic parts slide on the shaft to cause wear.
