In the demanding world of fluid handling, finding the right balance between technical reliability and supply chain flexibility is critical. For maintenance teams and plant engineers currently utilizing AESSEAL® SISS-SMCC or CKDmodels, FBU Sealing Technology (Suzhou) offers precision-engineered alternatives: the KSC and KDC series.
Our stationary cartridge seals are designed for direct interchangeability, ensuring that your transition to FBU technology is seamless, cost-effective, and performance-driven.
Why Choose Stationary Cartridge Seals?
Both the FBU and AESSEAL® models mentioned here utilize stationary face compensation technology. Unlike traditional rotary seals, stationary seals keep the springs in a non-rotating position. This design is superior for:
High-speed applications: Eliminating centrifugal force on the springs.
Misalignment handling: Better accommodating shaft-to-bore perpendicularity issues.
Extended seal life: Reducing spring clogging and face distortion.
1. FBU KSC: The Direct Alternative to AESSEAL® SISS-SMCC
The FBU KSC is our standard stationary single seal solution, engineered specifically for high-efficiency OEM applications and ISO standard pumps.
Technical Comparison & Advantages
Feature | AESSEAL® SISS-SMCC | FBU KSC Alternative |
Design Type | Stationary Cartridge Single Seal | Stationary Cartridge Single Seal |
Size Range | 1.000” to 3.375” (24mm - 85mm) | 1.000” to 4.000” (24mm - 100mm) |
Pressure Limit | Standard Industrial Limits | Up to 25 bar |
Temp. Limits | Standard Application Range | Up to 220°C (High Speed) |
Standard Ports | Quench, Flush, and Drain | Quench, Flush, and Drain (Modular) |
Key Advantage of FBU KSC: The KSC features a solid seal structure that significantly reduces face deformation under extreme temperature fluctuations. Its ability to handle pressures up to 25 bar and temperatures up to 220°C makes it a robust choice for hazardous chemicals and high-energy sectors.
2. FBU KDC: The Reliable Replacement for AESSEAL® CKD
The AESSEAL® CKD is a staple in general industrial applications. The FBU KDC serves as its functional equivalent, mirroring the modularity and "plug-and-play" convenience of the CKD series.
Performance Highlights:
API Plan 62 Compatibility: Like the CKD, our KDC can be equipped with throttle bushings or oil seals to support API Plan 62 (external quench), maximizing seal life by controlling the environment around the seal faces.
Non-Shaft-Fretting: Our design utilizes a sleeve elastomer drive, ensuring no metal-to-metal contact that could damage the pump shaft or sleeve.
Hydraulic Balancing: All KDC seals use hydraulically balanced face technology, which reduces power consumption and heat generation at the contact point.
Applicable Industries and Chambers
Both the KSC and KDC are designed to fit ISO2858 standard chambers and other compact pump housings. They are ideal for:
Petrochemical & Chemical Processing: Handling volatile and hazardous fluids.
Pulp & Paper: Replacing traditional packing in demanding environments.
Water & Environmental Engineering: Reliable sealing for wastewater and treatment plants.
Food & Beverage: Using FDA-compliant materials for hygienic safety.
FAQ
1: Are FBU KSC and KDC seals direct "drop-in" replacements for AESSEAL® models?
Yes. Our seals are designed to match the envelope dimensions and bolt patterns of the SISS-SMCC and CKD series, requiring no modifications to your existing pump stuffing box or shaft.
2: Can FBU seals handle the same chemical media as the original models?
Absolutely. We offer a full range of metallurgy (316SS, Alloy 20, Hastelloy) and face materials (Silicon Carbide, Tungsten Carbide, Carbon) to match or exceed the chemical resistance of your current setup.
3: Do you provide support for API Plan 62 or 52/53?
Yes, our modular gland designs come standard with Quench, Flush, and Drain ports, allowing for easy integration with environmental control plans to extend seal MTBF (Mean Time Between Failure).
4: How does the lead time compare for FBU products?
As a manufacturer, FBU Sealing Technology maintains a robust inventory of modular components, often allowing us to offer shorter lead times than larger global distributors.
