Pusher

Pusher Mechanical Seals

Pusher Mechanical Seals are designed for dynamic industrial applications where axial movement is required to maintain consistent face pressure. These seals use multiple secondary sealing elements that “push” against the sealing faces, allowing them to compensate for wear, pressure fluctuations, and shaft misalignment.

Pusher seals deliver stable, reliable performance in pumps and rotating equipment operating with varying temperatures, pressures, and process media.

Key Features

• Axial movement capability for automatic face adjustment

• High-pressure and high-temperature resistance

• Effective sealing for abrasive, corrosive, or contaminated fluids

• Reduced wear due to uniform face loading

• Available in single and double configurations

• Compatible with a wide range of elastomers and material combinations

Applications

• Chemical and petrochemical processing

• Oil & gas and refinery operations

• Water and wastewater treatment

• Power generation systems

• Food, pharma, and hygienic processing

• Industrial pumps, mixers, and compressors

Why Choose Pusher Mechanical Seals?
Pusher seals offer superior reliability in dynamic environments, delivering extended seal life, reduced leakage, and performance stability under demanding operating conditions. They are a versatile and cost-effective choice for modern pumping systems.
