Product Overview
Multi spring balanced seals use multiple small coil springs arranged evenly around the seal to apply uniform axial force on the seal faces. This balanced design reduces the hydraulic closing force acting on the faces, making the seal ideal for high-pressure applications.
Their compact, modular construction ensures uniform face wear, excellent performance under varying pressures, and the flexibility to handle both clean and slightly contaminated liquids.
Key Features
✔ Multi Spring Arrangement: Distributes face load evenly, ensuring consistent sealing and reduced distortion under pressure.
✔ Balanced Design: Minimizes face loading from process pressure, extending seal and equipment life in high-pressure services.
✔ Handles Higher Speeds & Pressures: Suitable for applications with elevated pressures and shaft speeds, reducing operational risks.
✔ Compact Axial Length: Fits into standard stuffing boxes, making installation and retrofitting straightforward.
✔ Available in Cartridge & Non-Cartridge Versions: Meets different installation and maintenance preferences.
✔ Field-Replaceable Faces & Secondary Seals: Simplifies servicing and prolongs seal lifecycle.
Materials of Construction
GSI multi spring balanced seals are manufactured from high-grade materials to withstand aggressive process conditions, including:
Seal Faces: Silicon Carbide, Tungsten Carbide, Carbon, Ceramic — selected to match your fluid and operational conditions
Secondary Seals: FKM (Viton), EPDM, PTFE, Kalrez or FFKM for extreme chemical and thermal resistance
Metal Parts: SS 316, Duplex Stainless Steel, Hastelloy, Alloy 20 for corrosion and pressure resistance
Springs: SS 316, Inconel, or Hastelloy for superior fatigue and corrosion performance
Our wide range of material options ensures compatibility with your specific media, pressure, and temperature requirements.
