BurgSeal® Aramid Family
BurgSeal® G503
Construction:
Made from high-quality, smooth synthetic aramid endless fibers (Kevlar) with PTFE impregnation and lubricant additives. The high stability of aramid fibers requires shafts and protective sleeves to have a surface hardness of 40-60 HRC to prevent contact surface wear.
Applications:
• Pumps, valves, and mixers in high-pressure systems
• Equipment exposed to aggressive chemicals and abrasives
BurgSeal® 503 II
Construction:
Constructed from smooth synthetic aramid endless fibers (Kevlar) with double PTFE impregnation. This design ensures gentle packing on the shaft sleeve, thanks to the special braiding construction by BurgSeal. Suitable for applications with lower abrasives and higher pressure and speed.
Applications:
• High-speed pumps and mixers
• Equipment handling less abrasive media
BurgSeal® W503
Construction:
Manufactured from Meta-aramid fibers, this product is impregnated with PTFE and is silicon oil-free. Its design retains the strength of Kevlar while being gentler on shafts, making it ideal for higher-speed applications without compromising durability.
Applications:
• High-speed rotating equipment
• Applications requiring gentle packing on sensitive shaft surfaces
BurgSeal® 506
Construction:
Made from smooth synthetic aramid endless fibers (Kevlar) with double graphite impregnation, this product is designed for high-temperature environments. It ensures temperature resistance along with high pressure and speed performance.
Applications:
• High-temperature pumps and valves
• High-pressure equipment in industrial processes
BurgSeal® W503 (Second Version)
Construction:
This special braid construction is made from PTFE and Kevlar yarns for corner reinforcement, designed to avoid extortion in plungers. The combination of both materials provides the benefits of pure PTFE and Kevlar with PTFE impregnation. Released by FMPA Stuttgart for use in the foodstuffs industries.
Applications:
• Food processing equipment
• Plunger pumps and high-speed systems
BurgSeal® 540
Construction:
A special braid construction combining PTFE with incorporated graphite compound and lubricant (GFO) with Kevlar staple yarns for corner reinforcement. This blend avoids extortion in plungers while combining the properties of pure PTFE and Kevlar for high-performance sealing.
Applications:
• Plunger pumps and high-pressure equipment
• Industrial processes requiring both chemical resistance and strength
BurgSeal® Z540
Construction:
Similar to type 540, Z540 uses PTFE with incorporated graphite compound and lubricant (GFO), combined with Kevlar staple yarns for reinforcement. This construction is ideal for demanding environments, providing the sealing strength of Kevlar and the chemical resistance of PTFE with graphite.
Applications:
• Abrasive media pumps
• High-temperature and high-pressure systems
