Gas (dry gas) Seal

Gas-lubricated mechanical seals are high-performance mechanical seals engineered specifically to prevent gas leakage between rotating and stationary components in critical equipment such as compressors, turbines, and high-speed pumps. Unlike conventional liquid-lubricated seals, gas seals operate on a non-contacting principle using a thin film of gas—typically air, nitrogen, or process gas—as the sealing medium.

This gas film creates a stable and controlled gap between the seal faces, minimizing friction, virtually eliminating wear, and significantly reducing energy consumption. Their design is ideally suited for high-speed, high-pressure, and hazardous gas environments where leakage control, equipment reliability, and efficiency are paramount. Gas seals also contribute to extended equipment life, lower operating costs, and reduced emissions, making them a preferred choice in modern rotating machinery across the oil & gas, petrochemical, and power generation industries.

Key Features;

  • Leakage Control: Effectively minimizes gas leakage, improving system reliability.
  • High Efficiency: Reduces power loss and eliminates the need for liquid lubrication.
  • Factory Assembled & Tested: Ensures reliability and performance before installation.
  • Multiple Spring Type: Ensures uniform face loading for consistent sealing performance.
  • Cartridge Construction: Pre-assembled unit for simplified installation and maintenance.
  • Hydraulically Balanced Type: Reduces face load and minimizes wear, extending seal life.
  • Metric and Inch Sizes Available: Compatible with a wide range of equipment specifications.
  • Independent of Unidirectional Rotation: Functions effectively regardless of shaft rotation direction.
  • Rotary & Stationary Spring: Designed for flexibility in various installation and operational conditions.
  • Quick Install & Easy Removal: Streamlined design allows for fast maintenance and reduced downtime.
  • Supplied with Buffer Gas Supply System: Ensures optimal sealing performance and prevents contamination.
  • Single & Double Seal: Available in both configurations to suit different pressure and containment requirements.
  • Application in High-Speed Machinery: Ideal for turbo compressors, centrifugal compressors, and other rotating equipment.
  • Non-contacting Design: Utilizes aerodynamic or hydrostatic forces to maintain a gap between the sealing surfaces, minimizing friction and wear.
  • Material Compatibility: Made from high-performance materials such as carbon, ceramics, and specialized metals to withstand harsh operating conditions.

Specification;

Application Gas-lubricated mechanical seals are designed for demanding services in the chemical and petrochemical industries, refineries, and gas processing plants, where both gases and low‑viscosity liquids must be sealed with minimal emissions. Typical equipment includes centrifugal and screw compressors, blowers, gas boosters, and low‑viscosity process pumps handling high‑purity, toxic, flammable or environmentally hazardous media. These seals are ideal wherever leak-free operation, product purity, and compliance with stringent environmental and safety regulations (such as API 692 guidelines for seal gas systems) are critical requirements.
