In the demanding world of fluid handling, maintenance engineers and procurement specialists are constantly seeking the optimal balance between reliability, lead times, and cost-efficiency. While the EagleBurgmann CARTEX series has long been a staple in the industry, Fubu Sealing Technology (FBU) has developed the KSC and KDC series to provide a seamless, high-performance alternative that meets the exact same technical rigors.

Whether you are looking to replace an existing single seal (CARTEX-SN) or a dual seal (CARTEX-DN), FBU’s solutions offer a direct "drop-in" replacement without the need for equipment modification.

1. Single Seal Replacement: FBU KSC vs. EagleBurgmann CARTEX-SN

For applications requiring a standard stationary single seal, the FBU KSC is engineered to match the versatility and robustness of the CARTEX-SN.

Technical Comparison

Both seals utilize stationary face compensation technology, which is critical for maintaining seal integrity in high-speed applications where shaft misalignment or deflection might occur.

Why Choose FBU KSC? 

• No Seal Face Drop: Our high-speed limits ensure that even at 220°C, there is no displacement of the seal face.

• Easy Conversion: Designed to replace traditional packing or older seal models in ISO 2858 standard chambers.

• Modular Design: The containerized design allows for rapid installation, reducing downtime during maintenance turnarounds.

 

2. Double Seal Replacement: FBU KDC vs. EagleBurgmann CARTEX-DN

When handling hazardous, abrasive, or high-pressure media, double seals are non-negotiable. The FBU KDC is the direct equivalent to the EagleBurgmann CARTEX-DN, offering a dual-seal solution with integrated circulation technology.

Technical Comparison

The KDC series excels in environments where the CARTEX-DN is typically found, such as the chemical, petrochemical, and power generation sectors.

Why Choose FBU KDC?

• Superior Metallurgy: While standard seals often use basic stainless steel, FBU offers Duplex Steel, 904L, and Alloy 276 as standard options for the "wet parts," providing superior corrosion resistance in aggressive media.

• Optimized Cooling: The integrated pumping ring and bi-directional diversion ensure efficient barrier fluid circulation, significantly extending the seal's service life.

• Stable Performance: The solid seal structure is specifically designed to reduce deformation under extreme temperature fluctuations.

Industrial Applications

• Both the FBU KSC and KDC series are designed for universal application across a wide spectrum of industries:

• Chemical & Petrochemical: Handling volatile and corrosive fluids.

• Water & Wastewater: Ideal for standardizing pump fleets and replacing gland packing.

• Pharmaceutical & Food: Meeting clean-room standards with reliable, non-contaminating designs.

• Marine & Offshore: Robust enough for the harsh conditions of saltwater and high-vibration environments.

The FBU Advantage: Beyond the Specs

Choosing FBU Sealing Technology isn't just about finding a part number that fits. It’s about Efficiency and Reliability. Our seals are designed to be standardized solutions for OEM customers who require high efficiency without compromising on the technical features of premium global brands.

Key Takeaway: If your facility currently utilizes EagleBurgmann CARTEX-SN or DN models, FBU KSC and KDC offer a 100% compatible, high-performance alternative that can be integrated into your existing maintenance workflow immediately.

FAQ

1. Are FBU seals direct "drop-in" replacements for EagleBurgmann?

Yes. The FBU KSC and KDC series are designed to the same dimensional standards as the CARTEX-SN and DN series. They fit the same seal chambers (including ISO 2858) without any modification to your pumps or equipment.

2. Can I use FBU KSC/KDC for both metric and imperial shaft sizes?

Absolutely. We provide a full range of sizes from 24mm to 100mm (1.000" to 4.000"). Custom sizes outside this range are also available upon request to meet specific OEM requirements.

3. How does the temperature and pressure resistance compare?

FBU seals are engineered for high-performance environments. Our KSC and KDC models handle pressures up to 25 bar and temperatures up to 220°C, matching the operating window of the CARTEX series.

4. Do I need to change my piping plans when switching to FBU KDC?

No. The FBU KDC is compatible with standard piping plans (such as API Plan 52, 53A, etc.) and works seamlessly with existing barrier fluid systems or thermosiphon vessels.

5. What materials are available for aggressive chemical environments?

For highly corrosive applications, we offer wet parts in 904L, Duplex Steel, and Alloy 276, ensuring that the seal housing is as resilient as the seal faces themselves.
