Multi Spring Unbalanced Seals
Proven Multi Spring Unbalanced Sealing Solutions for General Industrial Applications
At GSI – Globe Seal Industries, we design and manufacture reliable multi spring unbalanced seals that offer consistent, economical sealing for a wide range of low to medium pressure applications. These seals combine the versatility of multi spring technology with the simplicity of an unbalanced design — making them the go-to choice for general process industries.
Product Overview
Multi spring unbalanced seals incorporate several small coil springs uniformly positioned around the seal, ensuring even axial loading on the seal faces. Unlike balanced seals, these are designed to handle lower hydraulic loads, making them highly cost-effective for moderate pressure and clean to lightly contaminated liquids.
Their compact and modular construction allows easy installation into standard stuffing boxes and ensures dependable sealing across diverse process conditions.
Key Features
✔ Multiple Springs for Even Face Loading: Provides uniform pressure around the seal faces, ensuring stable operation and predictable wear patterns.
✔ Unbalanced Design: Ideal for applications with low to moderate pressures, reducing overall seal complexity and costs.
✔ Compact Axial Footprint: Fits easily into standard pump stuffing boxes, simplifying retrofits and replacements.
✔ Flexible for Both Rotations: Suitable for shafts rotating clockwise or counter-clockwise, simplifying inventory.
✔ Available in Cartridge & Component Styles: To suit your specific installation and maintenance preferences.
✔ Replaceable Seal Faces & Elastomers: Facilitates quick maintenance and reduces long-term ownership costs.
