Conical Spring Seals
Compact, Versatile Sealing with Conical Spring Mechanical Seals
At GSI – Globe Seal Industries, we design and manufacture robust conical spring seals that deliver dependable performance across a wide range of light to medium-duty pumping and rotary equipment applications. Their streamlined, versatile design makes them ideal for standard process fluids, water, and mild chemical services where simplicity, reliability, and cost-effectiveness are key.
Product Overview
Conical spring seals feature a unique open, conically wound single spring that ensures uniform axial face loading while effectively clearing solids and preventing clogging. This design is especially suited for services where the fluid may carry small suspended particles or where compact seal dimensions are essential.
These seals are available in multiple face, elastomer, and metal combinations, making them adaptable to various pump designs and process requirements.
Key Features
✔ Open Conical Single Spring: Ensures continuous self-cleaning action, preventing clogging by solids or slurry particles.
✔ Compact & Modular Design: Fits into small stuffing boxes and makes retrofitting to older equipment straightforward.
✔ Handles Minor Shaft Misalignments: Accommodates small axial and radial shaft movements without compromising sealing integrity.
✔ Easy Assembly & Disassembly: Simplified construction reduces downtime during maintenance or seal face replacement.
✔ Flexible Rotational Direction: Suitable for clockwise or counter-clockwise shaft rotations, reducing inventory requirements.
✔ Multiple Configurations Available: Offered in balanced or unbalanced variants depending on your pressure needs.
Materials of Construction
GSI conical spring seals are engineered using high-quality materials to suit diverse process environments, including:
Seal Faces: Carbon, Ceramic, Silicon Carbide, Tungsten Carbide
Secondary Seals: Nitrile (Buna-N), EPDM, Viton (FKM), or PTFE for optimal chemical compatibility
Metal Components: SS 304, SS 316, Alloy-20 for enhanced corrosion resistance
Spring: SS 316 or specialty alloys to handle aggressive media
We match materials precisely to your process fluids, temperature ranges, and mechanical demands.
