GLS, GSS, and GSG Seal Brochure

Product catalog summary

Overview: The document discusses the design and features of seals for integrally geared API pumps and compressors, focusing on the GLS, GSS, and GSG models. These seals are engineered for high reliability in high head, low flow equipment.

GLS & GSS Sealing Innovation: The seals are constructed with corrosion-resistant stainless steel and Alloy C-276 springs. The rotating face is made of silicon carbide, designed to reduce face distortion. The seals feature common cartridge and rotating assemblies suitable for both liquid and gas applications, with two carbon face designs for different liquid types.

GSS Gas Seal Features: These seals operate non-contacting up to 1250 psi, with low gas leakage and emissions. They incorporate a patented laser-machined wavy face design, enhancing reliability by reducing face distortion.

GLS Liquid Seal Features: These seals operate successfully up to 1250 psi in flashing hydrocarbons, with no measurable face wear. They are designed to minimize emissions.

GSG Sealing Innovation: The GSG design utilizes HST technology with a non-contacting wavy face to create a near-zero leakage seal, requiring no equipment modifications for replacement.

Operating Parameters: The seals can handle pressures from 0 to 1250 psi and temperatures from -80°F to 400°F. The GSS and GSG models can operate up to 36,000 rpm, while the GLS model operates up to 26,000 rpm.

Typical Configurations: The document outlines various configurations for pump and compressor applications, including single and dual non-pressurized and pressurized setups.
