Features
Dual Metal Bellows Architecture: Features two sets of edge-welded metal bellows (one on each seal face) that provide both spring force and dynamic sealing, eliminating all dynamically loaded elastomers. This design eliminates elastomer fatigue, wear, and degradation at extreme temperatures.
Cartridge-Mounted Design: Pre-assembled and factory-set to the correct compression, the X-200 simplifies installation and eliminates human error during setup. No manual adjustment of seal face gap or compression is required.
Balanced Seal Faces: Hydraulically balanced seal faces reduce face loading, enabling stable operation at high pressures and speeds while minimizing friction and wear.
Rotation-Independent Operation: Functions reliably regardless of shaft rotation direction, making it ideal for reversible pump applications.
Self-Cleaning Bellows Geometry: The rotating bellows module creates a self-cleaning effect that minimizes buildup of solids, sludge, or contaminants on seal faces, preventing face hang-up and extending service life.
Modular Construction: Available in single and dual (tandem/back-to-back) configurations, with options for flush ports, venting, and drain connections to support API 682 Plan 52, 53, or 54 support systems.
Shaft Protection Sleeve: Optional full-length shaft sleeve prevents shaft wear, corrosion, and fretting, extending pump shaft life.
Advantages
Extreme Temperature Resistance: Elastomer-free design enables reliable operation at cryogenic to ultra-high temperatures without seal degradation.
Superior Reliability: Dual metal bellows and self-cleaning geometry minimize wear and prevent clogging, reducing unplanned downtime.
Simplified Installation: Cartridge design eliminates alignment errors and reduces installation time by up to 50% compared to component seals.
Versatility: Compatible with a wide range of aggressive media, including acids, solvents, hydrocarbons, and high-temperature heat transfer fluids.
Compliance: Meets stringent industry standards for safety and environmental protection in critical process applications.
Applications
Oil & Gas Refining: Crude oil pumps, vacuum distillation units, fluid catalytic cracking (FCC) pumps, and aromatic processing.
Chemical Processing: High-temperature reactors, solvent recovery systems, and corrosive acid transfer pumps.
Power Generation: Boiler feed pumps, thermal fluid pumps, and waste heat recovery systems.
Petrochemical: Ethylene and propylene production, polymer processing, and high-pressure pipeline pumps.
