CSBT-4555 - Double Canister Studs with Debris Catcher, Pumping Ring, Inboard R-Bush, Ball Bearing & Single Row Setscrew Drive
The CSBT-4555 is a Double Cartridge Mechanical Seal, with ball bearing, pumping ring and single row setscrew clamp ring (for light-medium duty applications). The seal is specifically for mixers, agitators, and reactors operating in critical process environments.
Engineered for reliability and efficiency, this innovative rotary seal with resilient stationary faces, features monolithic and hydraulically balanced rotary seal faces, ensuring superior performance under varying pressures and speeds.
Designed for API Plan 52, 53 and 54 systems, the CSBT-4550 delivers enhanced operational performance, with many innovative design features and benefits as shown below.
Key Features:
- Double Seal – Provides optimal sealing for high-end, critical process applications and demanding process conditions.
- Integral Ball Bearing - Supplied with ball bearing, ideal for low-medium shaft load support. Can be supplied without bearing or with heavy duty shaft load carrying bearing.
- Hydraulically Balanced Seal Faces – Minimizes wear and enhances seal longevity, reducing maintenance and downtime.
- API Plan 53/54 Compatibility – Ideal for pressurized barrier fluid systems, ensuring zero process leakage and enhanced safety. Can also be employed in unpressurised Plan 52 barrier systems
- Debris Well - Catches any seal face wear/particles preventing entry into the process. Particles are removed from the seal via applying vacuum through the Debris Out (DO) orifice.
- Inboard Restriction Bush - Resilient / floating bush Controls flush media flow rate into equipment. Ideal for Clean in Place (CIP) and Steam in Place (SIP). Bush can be supplied in Carbon or PTFE/GFT material to suit the application.
- Stainless Steel Wetted Parts – Corrosion-resistant components for long-lasting durability in aggressive chemical and industrial applications.
- Cartridge Construction – The cartridge design provides easy installation and replacement, reducing assembly time and maintenance complexity.
- Resilient Mounted Stationary Faces – Provides a modicum of self-aligning to improve seal longevity.
- Integral Double Lip Seal - Prevents dust and debris collecting around outboard seal faces in top entry applications. Supplied with Drain connection orifice for leak face leakage detection.
- Single row Setscrew Shaft Clamping - Light duty shaft shafting.
- Monolithic Seal Faces - Monolithic (one piece) seal faces are the face of choice for high temperature applications over shrink fitted seal faces with differential thermal expansions of the bi-materials.
- Pumping Ring - Even at slow shaft speeds, the integral pumping ring helps to assist the natural thermspyhon effect, promoting heat removal at the seal faces. Cooler seal faces increase seal longevity and performance.
Upgrade your mixers, agitators, and reactors with the CSBT-4555 – where precision engineering meets modularity.
Applications:
- Chemical & Petrochemical Processing – Seals critical fluids in reactors and mixing equipment.
- Pharmaceutical & Biotechnology – Ensures contamination-free sealing in sterile processes.
- Food & Beverage Processing – Meets stringent hygiene and safety standards for product integrity.
- Oil & Gas Industry – Handles high-pressure and high-temperature environments.
- Specialty Coatings & Adhesives – Prevents leaks in mixing and blending applications.
Safe Operating Limits:
This seal incorporates best practice features and innovation as detailed in our technical blogs and white papers.
** Apply "industry standard" Pressure, Speed and Temperature de-rating factors, by shaft size and application. The safe seal performance characteristics are typical characteristics for each variable in isolation. The individual upper limit values of each variable should NOT be used in multiple combinations of Speed, Pressure and Temperature. Contact our Technical Sales Department for further details.
