Professional O-ring Mechanical Seal LP-250
Product Introduction
The LP-250 mechanical seal represents cutting-edge sealing technology specifically engineered for demanding applications in pulp screening and chemical processing systems. This single balanced seal features an innovative bellows design that maintains reliable performance under extreme conditions where conventional seals typically fail, particularly when handling abrasive media containing solid particles.
Material selection is optimized for superior durability: The stationary ring options include antimony-impregnated carbon graphite for general service and reaction-bonded silicon carbide (RB-SiC) for highly corrosive environments. The rotary ring utilizes fine-grained silicon carbide with micro-hardness exceeding Hv2800, complemented by specialized hydrodynamic grooves that maintain stable lubrication films at velocities up to 15m/s. Premium-grade fluoroelastomer secondary seals offer 40% wider temperature tolerance than standard NBR, retaining elasticity at 180℃. All metallic components are crafted from passivated 316L stainless steel, with heat-treated springs guaranteeing long-term corrosion resistance.
● Lepu Seal mechanical seal manufacturer & supplier can provide OEM service.
● We are a mechanical seal manufacturer with 25 years of production experience since 1998 in China.
Mechanical Seal Application
Designed to match major pressure screen models including ANDRITZ and Voith, the LP-250 simplifies installation with its patented alignment tool that ensures face parallelism within 0.0003 inches. Maintenance protocols recommend 2000-hour inspections of rotary ring wear and secondary seal monitoring through observation ports.
Proven in multiple Chinese pulp production lines, the LP-250 delivers over 8000 hours of continuous service in media with pH 3-11 and <15% solids content. Compared to OEM parts, it reduces maintenance costs by 30% while matching original performance standards. Our comprehensive technical support covers selection consulting, installation guidance, and troubleshooting to deliver optimal sealing solutions.
