High Pressure Cartridge Seals
Engineered High-Pressure Cartridge Seals for Demanding Industrial Environments
At GSI – Globe Seal Industries, we manufacture advanced high-pressure cartridge seals designed to withstand extreme process conditions involving elevated pressures, high speeds, and aggressive media. Built for reliability and safety, these seals ensure uninterrupted performance in critical operations where failure is not an option.
Product Overview
High pressure cartridge seals are heavy-duty mechanical seals engineered for services where standard seals may fail due to excessive pressure or mechanical stress. These pre-assembled seals simplify installation and are equipped to handle pressures up to 100 bar (1450 psi) or more, depending on configuration.
Designed with robust materials, multiple spring options, and precise face balancing, GSI high-pressure seals deliver leak-free, vibration-resistant operation in the most challenging applications.
Key Features
✔ Pressure Ratings up to 100 Bar or Higher: Specially designed to withstand extreme operating pressures without deformation or leakage.
✔ Hydraulic Face Balancing: Maintains optimal face loading, preventing distortion and reducing wear under variable pressures.
✔ Heavy-Duty Gland & Sleeve Construction: Reinforced components provide mechanical integrity under high loads and thermal stresses.
✔ Multiple Spring or Bellows Options: Axial springs or welded bellows designed to manage pressure spikes and shaft movement.
✔ Pre-Assembled & Factory Set: Easy, error-free installation with minimal setup time.
✔ Optional Quench, Flush & Drain Ports: For effective cooling, lubrication, and solid-handling support.
Materials of Construction
GSI high-pressure cartridge seals are manufactured using premium-grade materials tailored for safety, performance, and chemical compatibility:
Seal Faces: Tungsten Carbide, Silicon Carbide, Carbon, Ceramic
Secondary Seals: FKM (Viton), PTFE, Kalrez, EPDM, FFKM
Metal Parts: SS 316, Duplex & Super Duplex, Hastelloy, Inconel, or Alloy 20
Spring/Bellows: Inconel X-750, Hastelloy C, or other high-performance alloys
