CL99PR

CarLife^® 99PR is a high-flow circulation pump seal designed specifically for high-temperature processes exceeding 80℃. When equipped with a dedicated heat exchanger (WCHE) and a throat bushing on the process side, and utilizing the API Piping Plan23, it provides superior heat dissipation. 

CarLife^® 99PR is the ideal sealing solution for boiler feed water pumps (BFW Pump) and is commonly employed in high-temperature or volatile processes such as hot water, thermal oil, and chemical solvents, including applications in power plants.

• The patented cartridge design features innovative drop-proof springs, thereby speeding installation and maintenance.
• Our jumbo coil springs have better wear resistance than many other brands.
• Balanced design for both pressure directions, promoting a higher level of sealing stability.
• Flexible piping plans with a barrier/buffer fluid pressurized or unpressurized, depending on the application.
• Robust construction with large runout capability.
• Self-aligning compensates for shaft runout up to ±0.8 mm, increasing operational reliability.
• Micro-polished outer surfaces of O-rings for anti-stick mounting.
• Natural circulation heat exchanging design delivers bidirectional cooling flows at high flow rates, greatly extending MTBF (Mean Time Between Failures) because ofless heat.
• Monolithic sealing faces with precise dimensions and excellent resistance to wear.
• Low emissions design effectively contains VOC emissions.
• Interchangeable inboard and outboard sealing faces.
• Maximum interchangeability of parts among the CarLife^® family.

• Ability to tolerate short intermittent dry running in batch charging and discharging equipment.
• Prevent hazardous emissions of acidic, caustic, corrosive, volatile and toxic media.
• Withstand dry running involved with frequent starts and stops.
• Suitable for a wide range of rotating equipment, such as chemical process pumps, vertical pumps, centrifugal pumps, vacuum pumps and eccentric screw pumps.
• Widely used in the alcohol (e.g. methanol and ethanol), bio-diesel and corn processing industries.
• Suited for a variety of industrial applications, including refining, petrochemical, chemical, food and beverage, pharmaceutical, pipeline transportation, power generation, steel, semiconductor, electronics, biotechnology, water resource, and wastewater treatment.
