SEALLESS MAGNETIC DRIVE PUMPS - PFA LINED
Overview of FL Series Magnetic Drive Pumps - PFA Lined
Kweng Sealless Magnetic Drive Pumps – PFA Lined are engineered for superior chemical resistance, zero leakage and maintenance free operation. These sealless centrifugal pumps are ideal for handling corrosive, hazardous and toxic fluids in the most demanding industrial environments.
Key Features and Benefits
Corrosion-Resistant PFA Lining
High purity PFA lining ensures maximum compatibility with aggressive chemicals and acids, delivering long lasting performance.
Leak-Free Sealless Design
The magnetic drive eliminates the need for mechanicals seals, providing a 100% leak proof solution ideal for toxic and volatile liquids.
Rugged Construction for Demanding Environments
Built with non-metallic components and high grade engineering plastics, these pumps withstand extreme operating conditions.
Minimal Maintenance, Long Lifespan
Designed for lower wear operation, the FL series minimizes downtime and reduces lifetime ownership costs.
Compliance with ANSI B73.3 Standards
The FL Series complies with the ANSI B73.3 specification for sealless magnetic drive centrifugal pumps, ensuring standardized dimensions, performance and easy interchangeability with ANSI pumps in your facility.
Applications in Chemical and Hydrocarbon Industries
Acid Transfer Pumps
For safe and reliable sulfuric, hydrochloric and nitric acid handling.
Hydrocarbon Handling
Leak proof solution for flammable and volatile hydrocarbon fluids.
Hazardous Liquid Processing
For industries handling toxic or regulated materials zero emission risk.
Agrochemical and Fertilizer Industries
Designed for resistance against caustic and corrosive agrochemical formulations.
Technical Specifications
SEALLESS MAGNETIC DRIVE PUMPS – PFA LINED
- The ASME B73.3 standard guides the design of Kweng Sealless Magnetic Drive Pumps – PFA Lined.
- Kweng Sealless Magnetic Drive Pumps – PFA Lined are specifically designed for users who demand reliable and safe pumps for aggressive and corrosive chemical processing applications.
- All wetted parts are molded PFA components that can safely handle a wide range of corrosives, chemicals, and solvents up to 180°C without corrosion.
- Fully encapsulated inner magnet rotor & impeller are hermetically sealed with a PTFE + carbon fiber containment shell from the atmosphere and maintain magnet integrity for the life of the pump.
- A carbon fiber secondary containment shell delivers unprecedented reliability with zero eddy current loss.
- Kweng FL Series Sealless Magnetic Drive Pumps – PFA Lined are more efficient, safe and reliable pumps than conventional sealed pumps.
- The non-metallic containment doesn’t create any eddy currents, which means it doesn’t make any heat and saves money on energy costs.
- The secondary containment shell made of carbon fiber is very strong, so the pumps can handle high system pressures.
- As Kweng FL Series Sealless Magnetic Drive Pumps – PFA Lined do not have seals, there are no leaks, no emissions, and no costs related to seal maintenance
Kweng Sealless Magnetic Drive Pumps – PFA Lined are categorized as under:
- FL: The FL Series Kweng Sealless Magnetic Drive Pumps – PFA Lined are designed to cater to clean fluid services with no special requirements with generous fluid gaps..
Applications:
- The FL Series Kweng Sealless Magnetic Drive Pumps – PFA Lined can handle a broad range of process applications such as chemical processing, hydrocarbon processing, pharmaceutical chemicals, mining, battery manufacturing chemicals, etc.
The FL Series Kweng Sealless Magnetic Drive Pumps – PFA Lined has been designed to conform to ANSI B73.3 dimensional standards. The FL Series Kweng Sealless Magnetic Drive Pumps – PFA Lined are extremely rugged, which makes them ideal for rigorous duty in the chemical and hydrocarbon industries.
